THE GENERATION OF COMPUTERS Generation of computer is a term used to describe the evolution of computing, i.e. in other words it means improvement in the field of computer. There are six types of generation of computers: First Generation: Vacuum Tube Second Generation: Transistor Third Generation: Integrated Circuit Fourth Generation: Microprocessor Fifth Generation: Parallel Processing Sixth Generation:Reduced Instruction Set Chip (RISC) FIRST GENERATION1940-1956: Vacuum Tubes The first generation of computers used vacuum tubes(electric tubes about the size of light bulb) for circuitry and magnetic drums for memory and were often enormous, taking up entire rooms.

It uses machine language and machine code.

In this generation, punched cards, paper tape, magnetic tape, input and output were used.

MATERIAL USED Vacuum Tubes

Magnetic Drum

4,000 bits

Hard Wire Programs in computers SOME COMPUTER OF THIS GENERATION WERE: MARK 1 ENIAC UNIVAC EDVAC EDSAC CHARACTERISED BY: Unreliable Supported machine language Very expensive Difficult to program Slow input/output Need of A.C. They were very large and often take 1 room. Consume large amount of electricity & emitted a lot of heat. Non portable

First Generation Computer SECOND GENERATIONTransistors(1956-1963)

Transistors were used as the second generation computers. Smaller transistors replaced the vacuum tubes as the processing parts of a computer.

In this type of generation computers uses binary machine language or assembly language and high level programming language like FORTRAN, COBOL, ALGOL were used.

In this generation, magnetic cores were used as primary memory and magnetic tape and magnetic disks as secondary storage. There was also the creation of hardware and software. Th...

...nd video games, video game consoles, and video game handhelds available at the turn of the 21st century. Platforms of the sixth generation include the Sega Dreamcast, Sony PlayStation 2, Nintendo GameCube, and Microsoft Xbox, handhelds consoles include the Game Boy Advance. This era began on November 27, 1998 with the release of the Dreamcast, and it was joined by the PlayStation 2 in March 2000.

CONCLUSION As a result of the various improvements to the development of the computer we have seen the computer being used in all areas of life. It is a very useful tool that will continue to experience new development as time passes. Computers are used in various areas of our life. Education, entertainment, sports, advertising, medicine, science and engineering, government, office and home are some of theÿapplication areas of the computers. VIDEO ON GENERATION OF COMPUTERS

    In 500 B.C. the abacus was first used by the Babylonians as an aid to simple arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a "Calculating Clock". This mechanical machine could add and subtract up to 6 digit numbers, and warned of an overflow by ringing a bell. J. H. Mueller comes up with the idea of the "difference engine", in 1786. This calculator could tabulate values of a polynomial. Muellers attempt to raise funds fails and the project was forgotten. Scheutz and his son Edward produced a 3rd order difference engine with a printer in 1843 and their government agreed to fund their next project.

    Another example of the change in our technology over the last century is the change in the computer. In 1946, the first electronic computer called the ENIAC took up the space of a large room. Instead of using transistors and IC chips, the ENIAC used vacuum tubes. Compared to many computers now, the ENIAC is about as powerful as a small calculator. That may not be much, but it is a milestone because there would not be computers today if it were not for the ENIAC. As the years passed, the computer became smaller and more powerful. Today, more than half of the American population has a computer in their home. The personal computers today are thousands of times more powerful than the most powerful computers fifty years ago.

    We have the microprocessor to thank for all of our consumer electronic devices, because without them, our devices would be much larger. Microprocessors are the feat of generations of research and development. Microprocessors were invented in 1972 by Intel Corporation and have made it so that computers could shrink to the sizes we know today. Before, computers took a room because the transistors or vacuum tubes were individual components. Microprocessors unified the technology on one chip while reducing the costs. Microprocessor technology has been the most important revolution in the computer industry in the past forty years, as microprocessors have allowed our consumer electronics to exist.

    The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.

    The topic of magnetic disks is one that involves many physics related phenomenon. The intricate structure and design of “Magnetic Disks” (or hard disks) in computers include the principles of Fluid Flow, Rotational Motion, Electromagnetism, and more. This paper will focus mainly on the previously listed physics occurrences, and the design that goes into engineering the magnetic disk to include them. These physics principles are utilized in such a way that makes the hard disk a very common and useful tool, in this day and age. To most people, the magnetic disk is the most important, yet most mysterious, part of a computer system. A hard disk is a seal unit that holds computer data in the form of magnetic patterns.

    The Whirlwind computer had a video display that was controlled interactively by a light gun. The display attracted users much more than computer code. The Whirlwind computer became the basis for SAGE (Semi-Automatic Ground Environment), a defense command-and-control system developed for the Air force. In the 1960s Ivan Sutherland’s MIT doctoral thesis introduced a Sketchpad interactive drawing system, which established the theoretical groundwork for computer graphics software (Machover 14). In the mid-1960s, computer graphics was booming in private industry. General Motors had released DAC-1 a computer-aided design system, and Itek developed the Digigraphics electronic drafting machine. By the late 1960s the first storage-tube display terminals appeared, shortly followed by direct-view storage tube display terminals (DVST) which cost thousands of dollars; however this was an improvement to the tens to hundreds of thousands spent initially for display systems. In the 1970s Turnkey systems emerged, beforehand users had to develop software to make their hardware work however turnkey systems provided a haven to users from software issues.
