Q. what is MAC address ?Stands for "Media Access Control Address," and no, it is not related Apple Macintosh computers.

A MAC address is a hardware identification number that uniquely identifies each device on anetwork. The MAC address is manufactured into every network card, such as an Ethernet card orWi-Fi card, and therefore cannot be changed.

Q. How to find your MAC address(click Start, then Run, then type cmd in the text box.)

Type in ipconfig/all in the Command Prompt Windows.

The 12-digit Physical Address is the same as MAC address

Q. What is physical address?Every network interface has a MAC address (Media Access Controller) also known as thephysical address. This is the actual hardware address that the lowest level of thenetwork uses to communicate. The MAC address is used to assign the TCP/IP address bymeans of DHCP (Dynamic Host Configuration Protcol). For that reason, we need the MACaddress of a machine so that it can be properly, and easily configured for the network.

Q.what is default gateway?A mask used to determine what subnet an IP address belongs to. An IP address has twocomponents, the network address and the host address.

others usually use 'northbridge'), is traditionally one of the two chips in the core logic chipset on a PC

motherboard, the other being the southbridge. Separating the chipset into northbridge and southbridge is

common, although there are rare instances where these two chips have been combined onto one die when

design complexity and fabrication processes permit it.

Q. what is Southbridge?

The Southbridge, also known as the I/O Controller Hub (ICH), is a chip that implements the "slower"

capabilities of the motherboard in a northbridge/southbridge chipset computer architecture. Thesouthbridge can usually be distinguished from the northbridge by not being directly connected to the CPU.

Rather, the northbridge ties the southbridge to the CPU.

Q. What is disk cleanup?Disk Cleanup frees disk space by cleaning up areas that gather unneeded files. Using DiskCleanup regularly, along with using ScanDisk and DEFRAG and keeping your virus patterns up todate, will help keep your computer running smoothly.To run Disk Cleanup, follow the instructions below:

Q. what is recovery console?

Using the Recovery Console, you can enable and disable services, format drives, read and write data on a

local drive (including drives formatted to use NTFS), and perform many other administrative tasks. The

Recovery Console is particularly useful if you need to repair your system by copying a file from a floppy

disk or CD-ROM to your hard drive, or if you need to reconfigure a service that is preventing your

computer from starting properly.

Q. What is Cache?


7/8

Cache refers to temporary memory your computer uses to store the most recentlyviewed data. It can access its cache more quickly than any other part of your

computers memory. This is important because the more data your computer canstore in its cache, the more quickly it can process data. Therefore, the more cache

your processor has, the faster your computer will run.

Q. What is DIAL-UP?Accessing a network through a phone line and modem is called a dial-up

connection.

Q. What is DSL?Digital Subscriber Line (DSL) technology provides a dedicated digital circuit between a residenceand a telephone company's central office.13. Name 5 interface ports in the CPU?]1)serial portA serial device streams data as a series of bits, moving data one bit at a time. Examples of serial

devices include printers and MODEMs.

2) parllel portA parallel device streams data in a small group of bits simultaneously. Usually the group is a

single eight-bit byte (or possibly seven or nine bits, with the possibility of various control or paritybits included in the data stream). Each group usually corresponds to a single character of data.Rarely there will be a larger group of bits (word, longword, doubleword, etc.). The most commonparallel device is a printer (although most modern printers have both a serial and a parallelconnection, allowing greater connection flexibility). 3) USB 4) ADP 5) PS/2

17. CacheA type a computer memory that temporarily stores frequently used information for quick access.

18. Firewall:A set of related programs that protect the resources of a private network from users from othernetworks.Chip: A slang term for an integrated circuit.

Q. What is Hardware?The physical components that computer systems are comprised of, like hard disks, cpus,expansion cards, etc.

Q.Network :A network is a group of things that are connected together.

Q. Difference between dual core and core2duo?

Core 2 Duo is a brand name by Intel - Dual-Core is a generic description meaning

two separate physical cores in one chip package.

Q. Types of Networks:

LAN - The Local Area Network (LAN)WAN - The term Wide Area Network (WAN) usually refers to a network.MAN - Metropolitan Area Network

Q. What is Hub?


8/8

This is a hardware device that is used to network multiple computers together. It is a centralconnection for all the computers in a network, which is usually Ethernet-based. Information sentto the hub can flow to any other computer on the network. If you need to connect more than twocomputers together, a hub will allow you to do so. If you only need to network two computerstogether, a simple crossover Ethernet cable will do the trick.

What is Switch?A switch is used to network multiple computers together. Switches made for the consumer marketare typically small, flat boxes with 4 to 8 Ethernet ports. These ports can connect to computers,cable or DSL modems, and other switches. High-end switches can have more than 50 ports andoften are rack mounted.

Q. What is Hard Drive?The hard drive is what stores all you data. It houses the hard disk, where all your files andfolders are physically located. A typical hard drive is only slightly larger than your hand, yet canhold over 100 GB of data. The data is stored on a stack of disks that are mounted inside a solidencasement. These disks spin extremely fast (typically at either 5400 or 7200 RPM) so that data

can be accessed immediately from anywhere on the drive. The data is stored on the hard drivemagnetically, so it stays on the drive even after the power supply is turned off.

1.What is Troubleshooting?

Surfing: A Surfers Directory. The Largest Web Guide To Online Surf

Sites.

Q. what is data and information?

Data... data is raw. It simply exists and has no significance beyond its

existence (in and of itself). It can exist in any form, usable or not. It does

not have meaning of itself. In computer parlance, a spreadsheet generallystarts out by holding data.

Information... information is data that has been given meaning by way of

relational connection. This "meaning" can be useful, but does not have to

be. In computer parlance, a relational database makes information from

the data stored within it.
