TW Tech Glossary - Misplaced your bible? Well here it is! This truly took a while to complete and should be

used by all from beginners to advance techies. Look into it, you won't be sorry. (Very Resourceful)

N-Tier Application Architecture - N-tier application architecture provides a model for developers to create a

flexible and reusable application. By breaking up an application into tiers, developers only have to modify or

add a specific layer, rather than have to rewrite the entire application over, if they decide to change

technologies or scale up.

Parallel Computing- Parallelism has sometimes been viewed as a rare and exotic sub area of computing,

interesting but of little relevance to the average programmer. A study of trends in applications, computer

architecture, and networking shows that this view is no longer tenable. Parallelism is becoming ubiquitous, and

parallel programming is becoming central to the programming enterprise

Types of CPU's (Processors)- Upgradation is not something new to the field of computers. The computer has

come a long way from being just a calculating machine to a device that has become a necessity everywhere.

There is no industry or business that can't benefit from the usage of computers. Whether it's a managed

serverused fordedicated server hosting, personal desktop computers, or just your student

friendly notebook computers. The number of ways we can benefit from computers are numerous. The main

component of a computer has seen great changes in the past. First generation computers made use

of magnetic core memory whereas second generation saw the advent oftransistors. It was in the third

generation which began in the 1960s that gave rise to microprocessors.

Motherboards and Their Components - The motherboard represents the logical foundation of the computer. In

other words, everything that makes a computer a computer must be attached to the motherboard. From the

CPU to storage devices, from RAM to printer ports, the motherboard provides the connections that help them

work together.

227 Categorized CompTIA A Plus Q and A - CompTIA A+ Certification is widely recognized as the

firstcertificationyou should receive in an information technology(IT) career. Whether you are planning to

specialize in PC hardware, Windows operating system management, or network management, theCompTIA

A+ Certificationexams measure the baseline skills you need to master in order to begin your journey toward

greater responsibilities and achievements in information technology.

CompTIA A+ Certification is designed to be a "vendor-neutral" exam that measures your knowledge of

industry-standard technology.

The number one goal of this Q and A tutorial is a simple one: to help you pass the 2009 version of theCompTIA

A+ Certification Essentials Exam (number220-701) and the Practical Application Exam (number220-702), and

thereby earn yourCompTIA A+ Certification.

How Does a Motherboard Work?- In the event of taking an existing computer in for repairs only to be told that

a new motherboard is needed, it may sound like it is very expensive to buy. The good news is that

motherboards come by very cheap compared to purchasing a new PC. Many online retailers specializing in

computer parts sell motherboards for under $100 for a board that meets the requirements of building a high-

end computer for a lot more, although there are boards that cost more for what a builder needs for the ultimate

custom PC.

3 Best Motherboards of 2011 - The tech-savvy should be well aware of the benefits of building their own

personal computers. The relatively easy process of assembling various components can not only save you a

boatload of money, but also supply you with the perfect rig for your individual needs. Whether you are updating

a current machine or building a new one from scratch, the most important part you buy will probably be

the motherboard. Involved in almost every major computing process, a motherboard can make or break your

personal computer. However, technology is changing so rapidly that it's sometimes hard to know what's cutting

edge and what's outdated. But, no matter what you're looking for, we've got you covered. Below are the three

bestmotherboardsof 2011, as determined by price, performance and durability. Sincemotherboards tend to

be divided between Intel and AMD processors, a comparable board for the other processor is included in each

category.

What is a Motherboard?

The motherboard is the main circuit board inside your PC. Every components at some point communicates

through the motherboard, either by directly plugging into it or by communicating through one of the

motherboards ports. The motherboard is one big communication highway. Its purpose inside your PC is to

provide a platform for all the other components and peripherals to talk to each other.

Types of Motherboards

The type of motherboards depends

on the CPU it was designed for. You

can therefore categories

motherboards by which socket type

they have. e.g. Socket A, Socket 478

etc. The Type of motherboard you

buy is very important, as it will need

to house your CPU, and they are notinterchangeable. When buying a

motherboard, it will always tell you

what socket type it has.

3/25

As everything you have on the PC at some point needs the motherboard, you need to consider these

components when buying a motherboard. Foe example, if you have a lot of devices with a PCI interface that

you wish to use, there is little point buying a motherboard that only offers you 3 PCI slots. Like wise with

memory, you have to make sure that there are enough slots for the amount of memory you have or wish to

have.

The motherboard also needs the correct type of interface for your Memory, Graphics card, Hard disks and

other items as well. You will find that most motherboards offer everything you need however it needs checking

on when buying. Its especially important to pay detail to your motherboard if you want to use older components,

which a new motherboard may or may not support.

The major difference between motherboards that support the same CPU is the model of the chipset (more on

the chipset later). Different chipsets offer different performance and different features in terms of memory

support, AGP port speed, Multiplier numbers, Bus speeds and much more.

Speed of a Motherboard

Motherboards have got to be one of

the hardest components to measure

the speed of. Performance can really

only be measured by benchmarking

using the same components in

several motherboards of the same

type. You often find that

motherboards with the same chipset

have roughly the same performance

in real world tests. The minor

differences that do occur are down to

the quality of the materials used and

the quality of the manufacturing.

The Motherboards speeds that are

quoted on the box are maximum

supported speeds for other

components. For example motherboards will quote the maximum FSB (Front Side Bus) speed. Howeverwithout a CPU that also supports this speed, it will never be reached. Likewise when it quotes the maximum

memory speed. The memory of this speed has to be present.

What is a Motherboard Chipset?


4/25

A motherboard chipset controls all the data that flows through the data channels (buses) of the motherboard.

The primary function of the motherboard chipset is to direct this data to the correct area's of the motherboard,

and therefore the correct components.

Components of a Motherboard

The motherboard contains many connections for all type of components. Motherboards contain expansion slots

such as the ISA, PCI, AGP and DIMM sockets. It also contains external connections for your onboard sound

card, USB ports, Serial and Parallel ports, PS/2 ports for your keyboard and mouse as well as network and

Firewire connections.

So the motherboard has a massive part to play in the workings of your PC. Components that you buy all rely on

the motherboard to have the correct connections are available and working. Its best to buy a decent

motherboard especially if you plan on buying extra's in the future.

Tips

Scams

On-line auctions are now the number one location where thefts and scams will occur. If at all possible look at

the sellers history or profile. Always remember if it sounds to be good to true, it probably is.

Piracy

With the advances in technology it is now possible for anyone to make their own CDs it is possible that you

may be buying copied software which is illegal. Ensure that the software you are buying is a authentic copy,

documentation is included with the software, and the the CD does not appear to be burned. Generally burned

CDs will have a unusual color such as green or gold tint. However it is still possible for someone to make CDs

which can look like an ordinary CD. Another way of possibly determining if Illegal copy is the price. If for

example you see a Adobe Photoshop 5.0 for $20-$70 dollars its more then likely not a authentic copy. If it

sounds to be good to be true it probably is.

On-line Auctions

Companies such as E-bay or Yahoo may provide auctions which other people have the capability of listing

products that they are selling. We recommend that if you purchase through an an auction that you only pay by

check to prevent possible credit card fraud. If you need to user your credit card consider such options as

PayPal.


5/25

Return Policy

Ensure that the you verify what the resellers return policy may be incase the device is not functioning or is not

compatible with your computer.

Extra Note: Generally software cannot be returned to the place of purchase to help prevent software piracy.

Warranty

Verify the warranty on the product insuring that it is either provided by the manufacture of the product or the

place of purchase.

CPU Compatible

There are a wide variety of different types of CPU Sockets and Slots. When looking at purchasing a

motherboard ensure it is compatible with the CPU you have or that it will be compatible with the CPU you plan

on purchasing.

Upgrade

Upgrading a motherboard on the computer allows for new improved hardware to be added into the computer.

Upgrade

Upgrading a motherboard on the computer will speed up the overall performance of the computer. May not be

noticeable.

P4 System Optimization During Installation

When you install OS (other than WinXP) on an Intel 845 or 850 chipset based Pentium4 system, you need to

install the chipset driver before any other drivers, such as video card and sound card. Here's the installation

order.

1. OS (Win2000, 9x, Me)

2. Service Pack (if necessary)

3. Chipset Driver (usually in the CD that comes with your motherboard)

4. Drivers for Other Devices

It makes difference in performance, especially for video.

ASUS P4T + 1GB RDRAM + Win9X/Me = Not Good


6/25

Currently, ASUS P4T motherboards with 1GB of populated RDRAM will not work within a Windows 9X/Me

environment. This is not much of a tragedy since there is no particular reason to have 1GB of RAM on a

Win9X/Me system -- they only offer performance gains up to 512MB. However, this may cause problems for

people intending to do dual-boot systems, so be aware.

General P4 Guidelines

P4 systems currently require RDRAM memory (Rambus, RIMM..). The P4 platform will supposedly support

SDRAM by the end of 2001.


Boxed CPUs come with 2 x 64MB (total of 128MB) RIMM. These are not ECC. Intel may begin packaging 2 x

128MB RIMMs in the future.


RDRAM can be PC600, 700 or 800. The modules that come with the CPU are PC800, the fastest type.


Memory has to be installed as a pair. That's why the CPU comes with 2 x 64MB, instead of 1 x 128MB. The

pair of the memory has to be the same size, type (ECC or non-ECC) and speed (PC600 or PC800).


The case has to have 4 specific holes to support a big heatsink. An Antec case (#A58) and a mid tower case

(#A51) have the holes. The new aluminum cases do as well.


P4 motherboards have a new 12V connection. In order to use P4 with a regular power supply (without the 12V

connector), you need to use a PC Power&Cooling 12VATX adapter. This will convert the regular power

connection to 12VATX connection. Or, you can replace the power supply with one that already has the 12VATX

connection.

Microsoft Windows 2000 Patch for AGP Applications on AMD Athlon andAMD Duron Processors

AMD says, "An issue has been identified that could result in the corruption of video data shared between AGP

graphics adapters and AMD Athlon or AMD Duron processors when running Microsoft Windows 2000. This

issue is independent of system chipset and has been observed when running Ziff-Davis 3D Winbench 2000


7/25

and Mad Onion 3DMark 2000 in benchmarking mode. AMD and Microsoft have worked together to identify a

patch that involves adding a key to the registry. To add the key run the registry key installation file below or add

the registry key as detailed in Microsoft KnowledgeBase article Q270715. AMD recommends that AMD Athlon

and AMD Duron users with AGP graphics adapters running Windows 2000 install this patch.

Did You Know?

Most computer dealers say they build

their computers. If they carry a 3 year

warranty they are built by someone

else or the warranty is out of their back

pocket. Very few parts outside of

monitors carry anything pass one year,a few motherboards and even less

hardrives carry a 3 year warranty.

Integrated Motherboard: A motherboard where some or all of the internal input or output

devices are soldered into it.

Motherboard was the original name of the what is now called "main board." The difference is that

motherboards had "daughter boards" plugged into them. These "daughter boards" later became

simply "cards." Most brands of "main boards" have no cards, some don't even have plug-in slots

for such.

Integrated motherboards cause problems when wanting to upgrade your computer, also, LOTS

more money. EXAMPLE: Most Compaq /HPs, Dells, Gateways, IBMs have only three pieces

usable in an upgrade: the CD ROM ($25 new), hard drive (usually too small to be used, $65-$95

new) and the 3.5" drive ($10 new).

The motherboard is the main board in a computer that supports the processor (CPU) and all

internal input and output devices. Input and output devices are the video, modem, sound card,

hard drive and floppy controllers, memory (RAM), network cards. All modern PCI motherboards,

thanks to Intel, contain integrated floppy and IDE hard drive controllers. Again thanks to Intel &

Via almost all motherboard now have integrated sound also. Luckily we can disable the on-board

sound and put in a real Sound Blaster sound card.

Compaq/HP, Gateway, Acer, IBM, Pionex, Dell, NEC, Sony and Packard Bell computers make

good landfill after crushing. That is if they have biodegradable motherboards. A case of

Samsung and most Maxtor hard drives make fair boat anchors.

You can place an ISA card in a EISA slot. - True

Microsoft recently dared hackers to break into their server with the latest beta of Windows 2000 and its

firewall. Before anyone could, the server crashed by itself!

There was $8 billion in computer theft in 1996. Computer theft is one of the the fastest growing crimes

in America and the UK. In 1996 the theft of portable computers accounted for $650 million in losses in

the US. In the US, 30% of all reported thefts are computer related.

Every program has at least one bug and can be shortened by at least one instruction--from which, by

induction, one can reason that every program can be reduced to one instruction which doesn't work.





Circle Jerks! We have all been to them with their never ending pages that are impossible to get rid of.

It is called 'spanking the surfer' for not buying something and it is terrible web etiquette.

According to American Programmer, 31.1% of computer software projects get canceled before they

are completed, and 52.7% will overrun their initial cost estimates by 189%. 94% of project start-ups

are restarts of previously failed projects.

Things you learn about computers from the

movies: Powerful computers beep whenever

keys are pressed or the screen changes. They

also slow down the output on the screen so that it

doesn't go any faster than the audience can read

it. The *really* advanced ones emulate the sound

of a dot-matrix printer as the characters come

across the screen.



Basic Networking Tutorial- A network is any collection of independent computers that communicate with one

another over a shared network medium.A computer network is a collection of two or more connected

computers. When these computers are joined in a network, people can share files and peripherals such as

modems, printers, tape backup drives, or CD-ROM drives. When networks at multiple locations are connected

using services available from phone companies, people can send e-mail, share links to the global Internet, or

conduct video conferences in real time with other remote users. As companies rely on applications like

electronic mail and database management for core business operations, computer networking becomes

increasingly more important.

Remote Desktop Technology of Windows XP - Some people thought that the whole notion of terminal services

is a bit to technical for them to understand. Well, MicroSoft and our good friends that work for Bill Boy Gates

have come out with terminal services, changed the name and made it a whole lot easier to understand. Find out

how!

Using the Computer...Away From the Computer- You get to work on a Monday morning, and realise that you've

left the document you were presenting today back at home on your computer. How do you get it? Or maybe you

have a friend that has problems with their computer, and you know how to fix it, but only if you can see it. There

could be many more situations where you need to use a particular computer and you're not there. Enter the

range of programs known as VNC.

DNS Resolver Cache - To help speed up Web browsing, Windows XP comes with a local cache containing any

DNS addresses that have been looked up recently. Once an URL has been resolved by an Internet name

server into a numerical IP, the information is stored locally. Anytime your browser requests an URL, Windows

XP first looks in the local cache to see if it is there before querying the external name server used by your ISP. If

it finds the resolved URL locally it uses that IP. This is supposed to save time and cut down on Web traffic.

Kindness Online - So I thought this morning I would try to be the optimist, and give reason to hope for the future

of the Internet by drawing upon its present.

Now, it may seem like there is less hope today than there was before. People are less kind. There is less trust

around. I don't know. As a simple example, we could run a test here. How many people have ever hitchhiked? I

know. How many people have hitchhiked within the past 10 years? Right. So what has changed? It's not better

public transportation. So that's one reason to think that we might be declensionists, going in the wrong direction.

Networking Terms and Topics, Simplified! - This very much to the point guide highlights some important

networking terms and topics and simplifies them to us, the mere mortals.

How to Connect Two Laptops Using Bluetooth - Do you need to copy a heavy file from another laptop without

using pen drive or connecting cables? Of course, this can be done by using electronic transfer methods like ftp

or online data storage systems. However, these methods are not only time consuming, they often lead to

increased data transfer costs. Moreover, what if there is no internet connectivity available in the immediate

vicinity? Under such circumstances, you can connect two laptops through Bluetooth and exchange files

seamlessly.

Network Topologies- Ever wonder... how are all of these file, print, fax, and computer resources connected so

as to allow the typical desktop computer to access them? Network topologyrefers to the waynetworked

computers and network resources are connected. The three most widely used topologies are bus, ring,

and star. Note that the following network topology diagrams are logical views of the topologies they represent

and dont necessarily match the physical (electrical) interconnections on the networks.

History of TCP/IP -Internetworkingwith TCP/IPhas been around for many years-almost as many years

asUnixhas been available. TCP/IP, orTransmission Control Protocol/Internet Protocol, grew out of the

connectivity between the majorcomputing sites in government, educational, and research laboratories.

IP Spoofing and Sniffing - Sniffing and spoofingare security threats that target the lower layers of thenetworking

infrastructure supporting applications that use the Internet. Users do not interact directly with these lower layers

and are typically completely unaware that they exist. Without a deliberate consideration of these threats, it is

impossible to build effective security into the higher levels. Sniffing is a passive security attackin which a

machine separate from the intended destination reads data on a network. The term "sniffing" comes from the

notion of"sniffing the ether" in anEthernet networkand is a bad pun on the two meanings of the

word "ether." Passivesecurity attack are those that do not alter the normal flow of data on a communication

link or inject data into the link.

WikiLeaks, The Technical Aspect- Wikileaks has been in the news for quite some time now as it has rocked

many nations, embroiling itself in controversy over the fact that it has been releasing classified documents

which have been termed as potentially harmful for national security as well as international diplomacy. Amidst

all the confusion related to it's ethical and moral standards, people around the world have also speculated how

the site functions technically, as a site which has been so controversial, might be technologically sound as well

because various steps have already been taken in order to shut the Website down but none of them have

availed any results.

Brief History of Wi-Fi - Wi-Fi would certainly not exist without a decision taken in 1985 by the Federal

Communications Commission (FCC), America's telecoms regulator, to open several bands of wireless

spectrum, allowing them to be used without the need for a government license. This was an unheard-of move at

the time; other than the ham radio channels, there was very little unlicensed spectrum. But the FCC, prompted

by a visionary engineer on its staff, Michael Marcus, took three chunks of spectrum from the industrial, scientific

and medical bands and opened them up to communications entrepreneurs.

Implement Chat Systems on an Intranet - It used to be that businesses had a major influence on what types of

products and services were available to the general public. In the early days of the Internet,networking LAN

technologies and needs were the driving force behind the creation of many software applications and tools that

users accessed. The growing popularity of the World Wide Web with casual computer users led to a paradigm

shift in how to approach usable software solutions for these users. Simple to install and use software

applications such as file sharing, e-mail and instant chat programs were instantly popular.

What is Computer Networking?A network is a collection of connected intelligent computing devices. The connection is not necessarily a fancy

one. A connection between two computers by direct cabling is qualified to be a network. By this definition, a

workstation which is loaded with a computer, a scanner, and a printer, is not treated as a network.

A network can consist of two computers connected together on a desk or it can consist of many Local Area

Networks (LANs) connected together to form a Wide Area Network (WAN) across a continent. The key is that

two or more computers are connected together by a medium and are sharing resources. These resources can

be files, printers, hard?drives, or CPU number-crunching power.

A Local Area Network (LAN) is a smaller network within one location or between several buildings A

Metropolitan Network (MAN, politically incorrect, no WOMAN!) is a midsize network spanning the city. A Wide

Area Network (WAN) is a giant network spanning across several cities or even several continents.

Did You Know?

Peer to Peer networking was around

even 30 years ago.

Internet itself has evolved from thebasic home networking.

What was the First long

distance Connection? In 1965

using a low speed dial-up

telephone line, MIT researcher

Lawrence G. Roberts working with Thomas Merrill, connected the TX-2 computer

in Massachusetts to the Q-32 in California. The phone lines weren't quite up to

the task!

Who coined the phrase 'World Wide Web'? Tim Berners-Lee in 1990. He's

also considered by most people as the person who started the whole thing

rolling.

How did the Internet Start and Why? It all started with the time-sharing of

IBM computers in the early 1960s at universities such as Dartmouth and

Berkeley in the States. People would share the same computer for their

computing tasks. The Internet also received help from Sputnik! After this

Russian Satellite was launched in 1957, President Eisenhower formed ARPA to

advance computer networking and communication.

What Does a CPU Do? - As the brain of your PC, the CPU allows you to operate software. And, of course,

there is a connection between the power of the computer and the work of the CPU.

N-Tier Application Architecture - N-tier application architecture provides a model for developers to create a

flexible and reusable application. By breaking up an application into tiers, developers only have to modify or

add a specific layer, rather than have to rewrite the entire application over, if they decide to change

technologies or scale up.

Parallel Computing- Parallelism has sometimes been viewed as a rare and exotic sub area of computing,

interesting but of little relevance to the average programmer. A study of trends in applications, computer

architecture, and networking shows that this view is no longer tenable. Parallelism is becoming ubiquitous, and

parallel programming is becoming central to the programming enterprise

Types of CPU's (Processors)- Upgradation is not something new to the field of computers. The computer has

come a long way from being just a calculating machine to a device that has become a necessity everywhere.

There is no industry or business that can't benefit from the usage of computers. Whether it's a managed

serverused fordedicated server hosting, personal desktop computers, or just your student

friendly notebook computers. The number of ways we can benefit from computers are numerous. The main

component of a computer has seen great changes in the past. First generation computers made use

of magnetic core memory whereas second generation saw the advent oftransistors. It was in the third

generation which began in the 1960s that gave rise to microprocessors.

Types of PC Cases - Computer cases come in a variety of colors, designs, materials and for those who wish

to bare all, there are clear acrylic cases available. You'll hear of all types of hardware lingo like: ATX computer

cases, full tower computer cases, desktop computer cases, custom computer cases,aluminum computer

cases, cheap computer cases, gaming computer cases, mini computer cases, and on and on and on...you

get the drift.

Virtex V4 SX - Thousand Core Processor- All computers have a Central Processing Unit (CPU) in which

contains Core Processing Chips that allow the CPU to run your programs. In the beginning, a desktop

computer had a chip contained transistors that let the CPU run one process at a time. As time went on, newer

Core Processors were developed that split the chip into two, four or up to 16 cores on one Core Processor,

allowing the CPU to run more than one process at a time. This greatly increased the processing time of the

computer.

3 Best Motherboards of 2011 - The tech-savvy should be well aware of the benefits of building their own

personal computers. The relatively easy process of assembling various components can not only save you a

boatload of money, but also supply you with the perfect rig for your individual needs. Whether you are updating

a current machine or building a new one from scratch, the most important part you buy will probably be

the motherboard. Involved in almost every major computing process, a motherboard can make or break your

personal computer. However, technology is changing so rapidly that it's sometimes hard to know what's cutting

edge and what's outdated. But, no matter what you're looking for, we've got you covered. Below are the three

bestmotherboardsof 2011, as determined by price, performance and durability. Sincemotherboards tend to

be divided between Intel and AMD processors, a comparable board for the other processor is included in each

category.

What is a CPU (Central Processing Unit)?

Sometimes we refer to the CPU as the system box or brain. It is the computer chip that does all of the

processing for the computer. Inside this tiny chip are millions of transistors (electrical switches) that are

connected so they can carry out mathematical calculations. Everything a computer does is essentially a

mathematical calculation.

How the CPU Works

To properly perform its job, the CPU must complete a

cycle of four steps. The first step in this cycle is to fetch a

instruction from a software program's memory. Once the

CPU fetches the instruction, its second step is to decode

the instruction. By decoding the instruction, the CPU is

able to organize the information from the instruction in a

manner that allows the CPU to complete the next step,

which is executing.

During the execution step, the CPU completes the

instruction. It accomplishes this by following the information gained during the decoding step. Once the CPU

has finished executing the instruction, the final step in this cycle is to write-back the results that occurred during

the execution step. The CPU can write-back the results to its own internal register, or to the main memory of

the computer.

Tips

What benefit does it (MMX) offer users?

MMX technology raises the PC experience to new levels, when software designed for the technology runs on

systems based on the new processor. It delivers 10 to 20 percent more processor performance over Pentium

processors at the same clock speed due to the microarchitectural enhancements.

Additional performance and/or enhancements in quality of graphics, video and sound may be achieved to the

extent that the programmer takes advantage of the technology. On the Intel Media Benchmark, which

measures multimedia performance, the processor delivers more than 60 percent performance improvement

over Pentium processors at equivalent clock speeds.

Power Supply

New CPUs require higher rating power supply. Hence always ensure that your power supply is rated at 350 W

at least.

Cool It!

Invest in good heatsink and fan combination for your processor.

Genuine Article

Always buy Genuine CPU. Check Hologram seal on Intel CPU box. In case of AMD, make sure that the plastic

casing is not broken.

Cache That Monkey

If you plan to do CPU intensive tasks such as graphic processing, gaming and animation go for CPU with 256

KB or more of L2 cache. The Pentium 4 Northwood has 512 KB of L2 cache. For gaming applications, go for

CPU which supports 3DNow! or SSE.

Palomino

If power requirement and heat dissipation are not an issue, you can go for cheap and affordable Palomino

cores.

Save the Money


17/25

If you want only basic office applications, you can go for cheap CPU like Cyrix M III processor. This cheap CPU

works with any socket 370 motherboard.

High End Users

For high end 3D design and CAD applications, you will require a processor with highest clock speed and the

largest on board cache memory. Pentium and Athlon processors are best for such type of applications.

Intel Based System:

CPU Cooling - COOL your CPU first. Then it will perform. Processor cooling is very important from

performance and reliability point of view. Always provide good quality cooling fan with high rated heatsink.

Intel Based System:

Extra 12 V Power For Pentium 4 - All Pentium 4 processors require extra 12 volt power supply. Make sure the

power supply for new processor has necessary four pin 12 V connector. This connector fits into the ATX 12 V

connector on your Motherboard.

Intel Based System:

Hyperthread Technology - Intel's 3.06 GHz processor incorporates Hyperthreading technology which gives

better CPU performance when running multiple applications simultaneously.

Intel Based System:

CPU Type - Willamette CPU's are fabricated using 0.18 micron fabrication process. Willamette requires more

power and generate more heat. New Northwood CPU's are fabricated using 0.13 micron fabrication process.

Northwood CPU's have L2 cache of 512 KB.

Intel Based System:

Intel Drivers - Intel supplies drivers for new 800 series chipsets including 845, 845 - DDR and 850 chipsets

called the Intel application accelerator driver. These drivers increase the performance of your IDE devices.

They offer better boot times and also surpass 137 GB limitation of the IDE drives in the native Window drivers.

SSE2 type of special instructions in Intel CPU's help deliver better performance with certain types of data.

AMD Based System:

CPU Cooling - COOL your CPU first. Then it will perform. Processor cooling is very important from

performance and reliability point of view. Always provide good quality cooling fan with high rated heatsink. Use

thermal paste for better contact between heatsink and CPU. If by chance you forget to connect the fan supply


18/25

and switch on the motherboard, you will damage the AMD CPU with in seconds. Always use CPU heatsink and

fan combination that is certified by AMD.

AMD Based System:

Proper Mounting - As bare Silicon is exposed at the top surface in AMD CPU, heatsink installation should be

done properly. You should not slide the heatsink on the top surface of CPU. A small scratch or friction may

damage CPU.

AMD Based System:

Power Supply - It is always better to go for minimum 300 w power supply for AMD based system.

AMD Based System:

Special Instructions: The 3DNow! instruction set streamline power of certain applications.

AMD Based System:

Memory: You can use SDRAM or DDR memory. SDRAM is cost effective option for basic applications.

However for demanding applications ( graphic or high end gaming), go for DDR memory. DDR memory is good

for high speed applications.

AMD Based System:

Type of Processor- AMD Duron processors offer reasonably good performance with respect to their price.

But as they are phased out, it is better to go for Athlon processor. They are available in old 0.18 micron

Palomino and new 0.13 micron Thoroughbred core. New technology requires less power and generates less

heat. Not all motherboards support them. Hence always ensure that your motherboard supports new CPU

before buying the motherboard. Extra check the motherboard manual.

Did You Know?

The first single chip CPU was the Intel

4004, a 4-bit processor meant for a

calculator (not Intel 8086). It processeddata in 4 bits, but its instructions were

8 bits long. Program and Data memory

were separate, 1K data memory and a

12-bit PC for 4K program memory (in

the form of a 4 level stack, used for

CALL and RET instructions). There were also sixteen 4-bit (or eight 8-bit) general purpose

registers.

The 4004 had 46 instructions, using only 2,300 transistors in a 16-pin DIP. It ran at a clock rate

of 740kHz (eight clock cycles per CPU cycle of 10.8 microseconds) - the original goal was1MHz, to allow it to compute BCD arithmetic as fast (per digit) as a 1960's era IBM 1620.

The 4040 (1972) was an enhanced version of the 4004, adding 14 instructions, larger (8 level)

stack, 8K program space, and interrupt abilities (including shadows of the first 8 registers).

Should Pioneer 10 and Pioneer 11 ever be found by an extraterrestrial species, the 4004 will

represent an example of Earth's technology.

Then came Intel 8086 (1978) - This chip was skipped over for the original PC, but was used in a

few later computers that didn't amount to much. It was a true 16-bit processor and talked with its

cards via a 16 wire data connection. The chip contained 29,000 transistors and 20 address lines

that gave it the ability to talk with up to 1 MB of RAM. What is interesting is that the designers of

the time never suspected anyone would ever need more than 1 MB of RAM. The chip was

available in 5, 6,, 8, and 10 MHz versions.

Intel was not the only manufacturer playing in the sandbox at the time. AMD put out its AM486

series in answer to Intel's counterpart. AMD released the chip in AM486DX4/75,

AM486DX4/100, and AM486DX4/120 versions. It contained on-board cache, power

management features, 3-volt operation and SMM mode. This made the chip fitting for mobiles in

addition to desktops. The chip found its way into many 486-compatibles.

If you have software that you want to reinstall, verify that you have the disks

Make sure that you have the original CDs or floppy disks so that you can reinstall the software programs

after you partition and format your drive. If you purchased an upgrade for a program, make sure that you

have the full version of the original program. Many upgrades for programs require a compliance check before

you can install the upgraded product. If you cannot find the original CDs or floppy disks, contact the software

manufacturer before you continue.

If you have updated device drivers for peripheral devices, back them up

If you have installed an updated device driver for your peripheral devices (for example, modems and

printers), make sure that you back up the new driver for the device to a location other than the drive that

you want to format and partition so that you can reinstall it after you install your operating system.

Configure your computer to start from the CD or DVD drive

To start your computer from the Windows XP CD, your computer must be configured to start from the CD or

DVD drive. In some cases, you may have to modify your computer's BIOS settings to set this configuration.

For information about how to configure your computer to start from the CD or DVD drive, see the

documentation that is included with your computer, or contact the computer manufacturer.

If you have a computer that cannot start from the CD or DVD drive and you need to start your computer from

the startup disk, make sure that you have the floppy setup disks so that you can run the Setup program from

the floppy disk drive.

Note You can obtain Windows XP Setup boot disks from Microsoft, but only by download. We provide the

Setup boot disks so that you can run the Setup program on computers that cannot use a bootable CD-ROM. If

you can start your computer from a CD-ROM or from a network-based installation, we strongly recommend

that you use those installation methods instead. Future products will no longer support installation by using

the Setup boot disks.

then press ENTER to continue after you insert each disk.

b. If you are prompted, select any options that are required to start the computer from the CD or DVD

drive.

c. If your hard disk controller requires a third-party original equipment manufacturer (OEM) driver, press

F6 to specify the driver. For more information about how to use F6 to supply a third-party OEM device

driver while the Windows Setup program is running, click the following article number to view the

article in the Microsoft Knowledge Base:

d. At the Welcome to Setup page, press ENTER.

Note If you are using the Setup disks (six bootable disks), the setup prompts you to insert the

Windows XP CD.

e. Press F8 to accept the Windows XP Licensing Agreement.

f. If an existing Windows XP installation is detected, you are prompted to repair it. To bypass the repair,

press ESC.

g. All existing partitions and non-partitioned spaces are listed for each physical hard disk. Use the

ARROW keys to select an existing partition, or create a new partition by selecting the non-partitioned

space where you want to create a new partition. You can also press C to create a new partition using

non-partitioned space.

Note If you want to create a partition where one or more partitions already exist, you must first

delete the existing partition or partitions, and then create the new partition. You can press D to

delete an existing partition, and then press L (or press ENTER, and then press L if it is the System

partition) to confirm that you want to delete the partition. Repeat this step for each existing partition

that you want to include in the new partition. When all the partitions are deleted, select the

remaining non-partitioned space, and then press C to create the new partition.

h. To create the partition with the maximum size, press ENTER. To specify the partition size, type the

size in megabytes (MB) for the new partition, and then press ENTER.

i. If you want to create additional partitions, repeat steps g. and h.

j. To format the partition and install Windows XP, go to step 2.

If you do not want to install Windows XP, press F3 two times to exit the Windows Setup program, and

then do not follow the remaining steps in this article.

To format the partition without installing Windows XP, use a different utility.

Step 2: Format the hard disk and install Windows XP

a. Use the ARROW keys to select the partition where you want to install Windows XP, and then press

ENTER.

b. Select the format option that you want to use to format the partition. You can select from the

following options:

o Format the partition by using the NTFS file system (Quick)

o Format the partition by using the FAT file system (Quick)

o Format the partition by using the NTFS file system

o Format the partition by using the FAT file system

o Leave the current file system intact (no changes)

Notes

o If the selected partition is a new partition, the option to leave the current file system intact

is not available.

o If the selected partition is larger than 32 gigabytes (GB), the FAT file system option is not

available.

o If the selected partition is larger than 2 GB, the Windows Setup program uses the FAT32 file

system (you must press ENTER to confirm).

o If the partition is smaller than 2 GB, the Windows Setup program uses the FAT16 file

system.

o If you deleted and created a new System partition, but you are installing Windows XP on a

different partition, you are prompted to select a file system for both the System and Startup

partitions.

c. Press ENTER.

d. After the Windows Setup program formats the partition, follow the instructions that appear on the

screen to install Windows XP. After the Windows Setup program is finished and you have restarted

the computer, you can use the Disk Management tools in Windows XP to create or format more

partitions. For additional information about how to use the Windows XP Disk Management tools to

partition and format your hard disk, click the following article number to view the article in the

Additional notes

Before you can install an operating system such as Windows XP, you must first create a primary partition on

the first physical hard disk (Disk 0) on your computer. Then, you can format a file system on that partition to

create what is called the System partition.

Or, you can create a separate partition for the operating system on any physical hard disk. This is known as

the Startup partition. The System partition on Disk 0 can also be used as a Startup partition.
