    What is a computer?

    A programmable machine, the two principal characteristics of a computer are:

    1. It responds to a specific set ofinstructions in a well-defined manner.

    2.It can execute a prerecorded list of instructions (a program).

    Modern computers are electronic and digital. The actual machinery -- wires, transistors,

    and circuits -- is called hardware; the instructions and data are called software.

    All general-purpose computers require the following hardware components:

    Memory : Enables a computer to store, at least temporarily, data and programs.

    Mass storage device : Allows a computer to permanently retain large amounts of data.

    Common mass storage devices include disk drives and tape drives. Input device : Usually a keyboard and mouse, the input device is the conduit through

    which data and instructions enter a computer.

    Output device : A display screen,printer, or other device that lets you see what the

    computer has accomplished.

    Central processing unit (CPU): The heart of the computer, this is the component that

    actually executes instructions.

    Therefore this paragraph has been created with a listing of each of the first computers

    starting with the first programmable computer leading up to the computers of today.

    Keep in mind that early inventions such as the abacus, calculators, tablet machines,

    difference machine, etc. are not accounted for in this document.

    First programmable computer

    The Z1 originally created by Germany's Konrad Zuse in his parents living room in 1936

    to 1938 is considered to be the first electrical binary programmable computer.

    The first digital computer

    Short for Atanasoff-Berry Computer, the ABC started being developed by Professor

    John Vincent Atanasoff and graduate student Cliff Berry in 1937 and continued to be

    developed until 1942 at the Iowa State College (now Iowa State University). On October

    19, 1973, US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by

    Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic

    digital computer.

    The ENIAC was invented by J. Presper Eckert and John

    Mauchly at the University of Pennsylvania and began

    construction in 1943 and was not completed until 1946.

    It occupied about 1,800 square feet and used about

    18,000 vacuum tubes, weighing almost 50 tons.

    Although the Judge ruled that the ABC computer was

    the first digital computer many still consider the ENIAC to be the first digital computer.

    See the ENIAC definition for additional information about this computer.

    Because of the Judge ruling and because the case was never appealed like most we

    consider the ABC to be the first digital computer. However, because the ABC was never

    fully functional we consider the first functional digital computer to be the ENIAC.

    The first computer with RAM

    MIT introduces the Whirlwind machine March 8, 1955, a revolutionary computer that

    was the first digital computer with magnetic core RAM and real-time graphics.

    The first transistor computer

    The TX-O (Transistorized Experimental computer) and first transistorized computer is

    demonstrated at the Massachusetts Institute of Technology in 1956.

    The first stored program computer

    The early British computer known as the EDSAC is considered to be the first stored

    program electronic computer. The computer performed its first calculation on May 6,1949 and was the computer that ran the first graphical computer game.

    The first minicomputer

    In 1960 Digital Equipment Corporation released its first of many PDP computers the

    PDP-1.

    The first personal computer

    In 1975 Ed Roberts coined the term personal computer when he introduced the Altair

    8800. Although the first personal computer is considered to be the Kenback-1, which

    was first introduced for $750 in 1971. The computer relied on a series of switches for

    inputting data and output data by turning on and off a series of lights.

    The Micral is considered the be the first commercial non-assembly computer. The

    computer used the Intel 8008 processor and sold for $1,750 in 1973.

    The first workstation

    Although never sold the first workstation is considered to be the Xerox Alto, introduced

    in 1974. The computer was revolutionary for its time and included a fully functional

    computer, display, and mouse. The computer operated like many computers today

    utilizing windows, menus and icons as an interface to its operating system.

    The first laptop or portable computer

    The first portable computer or laptop is considered to be the Osborne I, a portable

    computer developed by Adam Osborne that weighed 24 pounds, a 5-inch display, 64 KB

    of memory, two 5 1/4" floppy drives, and a modem.

    IBM PCD later released the IBM portable in 1984, it's first portable computer that

    weighed in at 30 pounds. IBM PCD later announced in 1986 it's first laptop computer,

    the PC Convertible, weighing 12 pounds. And in 1994 introduces the IBM ThinkPad

    775CD, the first notebook with an integrated CD-ROM.

    The first PC (IBM compatible) computer

    In 1953 IBM shipped its first electric computer, the 701. Later IBM introduced its first

    personal computer called the "IBM PC" in 1981. The computer was code named and still

    sometimes referred to as the "Acorn" and had a 8088 processor, 16 KB of memory,

    which was expandable to 256 and utilizing MS-DOS.

    The first PC clone

    The first PC clone was developed by Compaq, the "Compaq Portable" was release in

    March 1983 and was 100% compatible with IBM computers and software that ran on

    IBM computers.

    ENIAC

    In February, the public got its first glimpse of the ENIAC, a

    machine built by John Mauchly and J. Presper Eckert thatimproved by 1,000 times on the speed of its contemporaries.

    UNIVAC I

    The UNIVAC I delivered to the U.S. Census Bureau was

    the first commercial computer to attract widespread public

    attention. Although manufactured by Remington Rand, the

    machine often was mistakenly referred to as the "IBM

    UNIVAC." Remington Rand eventually sold 46 machines at more than $1 million

    each.F.O.B. factory $750,000 plus $185,000 for a high speed printer.

    Kenbak-1

    The Kenbak-1, the first personal computer, advertised

    for $750 in Scientific American. Designed by John V.

    Blankenbaker using standard medium-scale and

    small-scale integrated circuits, the Kenbak-1 relied on

    switches for input and lights for output from its 256-

    byte memory. In 1973, after selling only 40

    machines, Kenbak Corp. closed its doors.

    1979

    Advertisment for Atari 400 and

    Atari introduces the Model 400 and 800 Computer.

    Shortly after delivery of the Atari VCS game console,

    Atari designed two microcomputers with game

    capabilities: the Model 400 and Model 800. The two

    machines were built with the idea that the 400 would

    serve primarily as a game console while the 800

    though they had technical and marketing problems,

    and faced strong competition from the Apple II,

    Commodore PET, and TRS-80 computers.

    1981

    IBM introduced its PC, igniting a fast growth of the personal computer market. The first PC

    ran on a 4.77 MHz Intel 8088 microprocessor and used Microsofts MS-DOS operating

    system.

    Commodore 64

    Commodore introduces the Commodore 64. The C64,

    as it was better known, sold for $595, came with

    64KB of RAM and featured impressive graphics.

    Thousands of software titles were released over the

    lifespan of the C64. By the time the C64 was

    discontinued in 1993, it had sold more than 22 millionunits and is recognized by the 2006 Guinness Book of

    World Records as the greatest selling single computer

    model of all time.

    Computer Storage.

    Secondary Storage Alternatively referred to as external memory and auxiliary storage, secondary

    storage is a storage medium that holds information until it is deleted or

    overwritten regardless if the computer has power. For example, afloppy disk

    driveandhard disk driveare both good examples of secondary storage devices.

    As can be seen by the below picture there are three different storage on a

    computer, although primary storage is accessed much faster than secondary

    storage because of the price and size limitations secondary storage is used with

    today's computers to store all your programs and your personal data.

    Finally, although off-line storage could be considered secondary storage, we've

    separated these into their own category because this media can be easily removed

    from the computer and stored elsewhere.

    Internal Storage

    There few types of internal storage. Primary storage, Main storage, Immediate

    access storage, RAM And ROM.

    RAM

    Pronounced ram, acronym for random access memory, a type of computer

    memory that can be accessed randomly; that is, any byte of memory can be accessed

    without touching the preceding bytes. RAM is the most common type of memory found

    in computers and other devices, such as printers.

    There are two different types of RAM: DRAM (Dynamic Random Access Memory) and

    SRAM (Static Random Access Memory). The two types differ in the technology they

    use to hold data, with DRAM being the more common type. In terms of speed, SRAM is

    faster. DRAM needs to be refreshed thousands of times per second while SRAM does

    not need to be refreshed, which is what makes

    it faster than DRAM. DRAM supports access

    times of about 60 nanoseconds, SRAM can

    give access times as low as 10 nanoseconds.

    Despite SRAM being faster, it's not as

    commonly used as DRAM because it's so

    much more expensive. Both types of RAM

    are volatile, meaning that they lose their contents when the power is turned off.

    In common usage, the term RAM is synonymous with main memory, the memory

    available to programs. For example, a computer with 8MB RAM has approximately 8

    million bytes of memory that programs can use. In contrast, ROM (read-only memory)

    refers to special memory used to store programs that boot the computer and perform

    diagnostics. Most personal computers have a small amount of ROM (a few thousand

    bytes). In fact, both types of memory (ROM and RAM) allow random access. To be

    precise, therefore, RAM should be referred to as read/write RAM and ROM as read-only

    RAM.

    Latest RAM s.

    The XDR2 memory architecture is the world's fastest memory system solution capableof providing twice the peak bandwidth per device when compared to a GDDR5-basedsystem. Further, the XDR2 memory architecture delivers this performance at 30% lowerpower than GDDR5 at equivalent bandwidth.

    ROM

    Pronounced ram, acronym for read-only memory, computer memory on which

    data has been prerecorded. Once data has been written onto a ROM chip, it cannot beremoved and can only be read.

    Unlike main memory (RAM), ROM retains its contents even when the computer is

    turned off. ROM is referred to as being nonvolatile, whereas RAM is volatile.

    Most personal computers contain a small amount of ROM that stores critical programs

    such as the program that boots the computer. In addition, ROMs are used extensively in

    calculators and peripheral devices such as laser printers, whose fonts are often stored in

    ROMs.

    A variation of a ROM is a PROM (programmable read-only memory). PROMs are

    manufactured as blank chips on which data can be written with a special device called a

    PROM programmer .

    Types of ROM Chips

    PROM

    Short for Programmable Read Only Memory, Programmable ROM, or

    PROM is a computer memory chip capable of being programmed. Once the PROM has

    been programmed, the information written is permanent and cannot be erased or deleted.

    A good example of a PROM is the computer BIOS.

    EPROM

    Short for Eras able Programmable Read-Only Memory, ERPOM is a memory

    chip that was invented by Dov Frohman that can be read from but not stored to.

    However, if exposed to ultraviolet light and can be reprogrammed if needed. Hardware

    manufactures use EPROM when it may be needed that the data contained on the

    EPROM needs to be changed. An EPROM chip is easily distinguishable by a small glass

    circle that exposes the chip that can be reprogrammed.

    EEPROM

    Short for Electrically Eras able Programmable Read-Only Memory, EEPROM is

    a PROM that can be erased and reprogrammed using an electrical charge.

    Unlike most memory inside a computer, this memory remembers data when the power is

    turned off. EEPROM is often used to store information for the computer's BIOS.

    CPU

    Pronounced as separate letters it is the abbreviation for central processing unit.

    The CPU is the brains of the computer. Sometimes referred to simply as the central

    processor, but more commonly called processor,

    the CPU is where most calculations take place. In

    terms of computing power, the CPU is the most

    important element of a computer system.

    On large machines, CPUs require one or more

    printed circuit boards. On personal computers and

    small workstations, the CPU is housed in a single

    chip called a microprocessor. Since the 1970's the

    microprocessor class of CPUs has almost completely overtaken all other CPU

    implementations.

    The CPU itself is an internal component of the computer. Modern CPUs are small and

    square and contain multiple metallic connectors or pins on the underside. The CPU is

    inserted directly into a CPU socket, pin side down, on the motherboard. Each

    motherboard will support only a specific type or range of CPU so you must check the

    motherboard manufacturer's

    specifications before

    attempting to replace or

    upgrade a CPU. Modern

    CPUs also have an attached

    heat sink and small fan that

    go directly on top of the CPU

    to help dissipate heat.

    Two typical components of a

    CPU are the following:

    The arithmetic logic unit (ALU), which performs arithmetic and logical operations.

    The control unit (CU), which extracts instructions from memory and decodes and

    executes them, calling on the ALU when necessary.

    Common sockets utilize retention clips that are designed to apply a constant force, which

    must be overcome when a device is inserted. For chips that sport a high number of pin

    outs, either zero-insertion force (ZIF) sockets or land grid array (LGA) sockets are used

    instead. These designs apply a compression force once either a handle (for ZIF type) or a

    surface plate (LGA type) is put into place. This provides superior mechanical retention

    while avoiding the added risk of bending pins when inserting the chip into the socket.

    CPU sockets are used in desktop and server computers (laptops typically use surface

    mount CPUs). Because they allow easy swapping of components, they are also used for

    prototyping new circuits.

    Function

    A CPU socket is often made up of plastic, a metal lever or latch, and metal

    contacts for each of the pins or lands on the CPU. Most packages are keyed to ensure the

    proper insertion of the CPU. CPUs with a PGA package are inserted into the socket and

    the latch is closed. This has the effect of physically securing and protecting the CPU as

    well as causing an electrical connection between all the CPU pins and the socket. In the

    case of LGA, the CPU is placed onto the socket and a latch is closed over the CPU,

    securing it. Most CPU sockets are designed to support the installation of a heatsink. It

    must be able to protect the CPU from the weight of the heatsink (often very heavy in

    weight relative to the CPU) particularly during the installation and removal, while also

    ensuring that the heatsink makes good thermal contact with the CPU.

    CONTROL UNIT

    The control unit maintains order within the computer system and directs

    the flow of traffic (operations) and data. The flow of control is indicated by the

    dotted arrows on figure 1-1. The control unit selects one program statement at

    a time from the program storage area, interprets the statement, and sends the

    appropriate electronic impulses to the arithmetic-logic unit and storage section to

    cause them to carry out the instruction. The control unit does not perform the

    actual processing operations on the data. Specifically, the control unit manages the

    operations of the CPU, be it a single-chip microprocessor or a fill-size mainframe.

    Like a traffic director, it decides when to start and stop (control and timing), what to

    do (program instructions), where to keep information (memory), and with what

    devices to communicate (I/O). It controls the flow of all data entering and leaving the

    computer. It accomplishes this by communicating or interfacing with the

    arithmetic-logic unit, memory, and I/O areas. It provides the computer with the

    ability to function under program control. Depending on the design of the computer,

    the CPU can also have the capability to function under manual control through

    man/machine interfacing. The control unit consists of several basic logically defined

    areas. These logically defined areas work closely with each other. Timing in a

    computer regulates the flow of signals that control the operation of the computer.

    The instruction and control portion makes up the decision-making and memory-type

    functions. Addressing is the process of locating the operand (specific information)

    for a given operation. An interrupt is a break in the normal flow of operation of a

    computer (e.g., CTRL + ALT + DEL). Control memory is a random-access

    memory (RAM) consisting of addressable storage registers. Cache memory is a

    small, high-speed RAM buffer located between the CPU and main memory; it can

    increase the speed of the PC. Read-only memory (ROM) are chips with a set of

    software instructions supplied by the manufacturer built into them that enables the

    computer to perform its I/O operations. The control unit is also capable of shutting down

    the computer when the power supply detects abnormal conditions. ARITHMETIC-

    LOGIC UNIT The arithmetic-logic unit (ALU) performs all arithmetic operations

    AMD Talks Llano & Radeon HD 6800

    Written by Rob Williams on October 19, 2010 In AMD Processors

    AMD invited both media and vendors down to Los Angeles last week to learn about the

    company's upcoming products and technologies, such as the Fusion-based Llano CPU

    (err, APU) and Radeon HD 6800 series. We were there, and have some preliminary

    information on both, as well as some light information about the event itself.

    Intel's Core i5-655K & i7-875K Unlocked Processors

    Written by Rob Williams on May 28, 2010 In Intel Processors

    Most of today's desktop CPUs, including budget models, tend to be

    good for overclocking. But for those who are looking for the ultimate

    in tweaking ability, Intel's mainstream models have left a bit to be desired. With the K

    series, though, it aims to remedy that situation by offering unlocked models at affordable

    prices.

    Phenom II X6 1090T - AMD Enters the Six-Core Arena

    Written by Rob Williams on April 28, 2010 In AMD Processors

    In March, it was Intel's turn, and this month, it's AMD's. That's right,

    we're at the point when Phenom II X6's are hitting the market and

    giving consumers a much less expensive six-core CPU to chose from. We're taking a

    look at AMD's top-end offering, the 1090T BE, and also a brief look at the company's

    new 890FX chipset.

    Intel's Core i7-980X Extreme Edition - Ready for Sick Scores?

    Written by Rob Williams on March 10, 2010 In Intel Processors

    It's official. We're now entering the six-core realm, thanks to Intel's

    Gulftown. The first model, Core i7-980X, is more than capable of

    delivering the sick scores that our title suggests, and along with it, we can begin to see

    some major benefits of the 32nm process. To sweeten the deal further, Intel even

    includes an effective new CPU cooler.

    Intel's Core i3-530 - The Budget Powerhouse?

    Written by Rob Williams on March 4, 2010 In Intel Processors

    reason was its budget $120 price tag. But if there's one thing that can make a budget chip

    interesting, it's overclocking, and fortunately, there's huge potential where this chip is

    concerned.

    keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are

    known as the motherboard's chipset.

    On most PCs, it is possible to add memory chips directly to the motherboard. You may

    also be able to upgrade to a faster PC by replacing the CPU chip. To add additional core

    features, you may need to replace the motherboard entirely.

    Motherboard is sometimes abbreviated as mobo.

    Main types of computers

    1.0Historic evolutionFirst Generation (1940-1956) Vacuum Tubes

    The first computers used vacuum tubes for circuitry and magnetic drums for memory,

    and were often enormous, taking up entire rooms. They were very expensive to operate

    and in addition to using a great deal of electricity, generated a lot of heat, which wasoften the cause of malfunctions.

    First generation computers relied on machine language, the lowest-level programming

    language understood by computers, to perform operations, and they could only solve one

    problem at a time. Input was based on punched cards and paper tape, and output was

    displayed on printouts.

    The UNIVAC and ENIAC computers are examples of first-generation computing

    devices. The UNIVAC was the first commercial computer delivered to a business client,

    the U.S. Census Bureau in 1951.

    Second Generation (1956-1963) Transistors

    Transistors replaced vacuum tubes and ushered in the second generation of computers.

    The transistor was invented in 1947 but did not see widespread use in computers until the

    late 1950s. The transistor was far superior to the vacuum tube, allowing computers to

    become smaller, faster, cheaper, more energy-efficient and more reliable than their first-

    generation predecessors. Though the transistor still generated a great deal of heat that

    subjected the computer to damage, it was a vast improvement over the vacuum tube.

    Second-generation computers still relied on punched cards for input and printouts for

    output.

    Second-generation computers moved from cryptic binary machine language to symbolic,

    or assembly, languages, which allowed programmers to specify instructions in words.

    High-level programming languages were also being developed at this time, such as early

    versions of COBOL and FORTRAN. These were also the first computers that stored

    their instructions in their memory, which moved from a magnetic drum to magnetic core

    technology. The first computers of this generation were developed for the atomic energy

    industry.

    Third Generation (1964-1971) Integrated Circuits

    The development of the integrated circuit was the hallmark of the third generation of

    computers. Transistors were miniaturized and placed on silicon chips, called

    semiconductors, which drastically increased the speed and efficiency of computers.

    Instead of punched cards and printouts, users interacted with third generation computers

    through keyboards and monitors and interfaced with an operating system, which allowed

    the device to run many different applications at one time with a central program that

    monitored the memory. Computers for the first time became accessible to a mass

    audience because they were smaller and cheaper than their predecessors.

    Fourth Generation (1971-Present) Microprocessors

    The microprocessor brought the fourth generation of computers, as thousands of

    integrated circuits were built onto a single silicon chip. What in the first generation filled

    an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in

    1971, located all the components of the computerfrom the central processing unit and

    memory to input/output controlson a single chip.

    In 1981 IBM introduced its first computer for the home user, and in 1984 Apple

    introduced the Macintosh. Microprocessors also moved out of the realm of desktop

    computers and into many areas of life as more and more everyday products began to use

    microprocessors.

    As these small computers became more powerful, they could be linked together to form

    networks, which eventually led to the development of the Internet. Fourth generation

    computers also saw the development ofGUIs, the mouse and handheld devices.
