Computer History: Classification of Generations of Computers

History of computing hardware (1960s–present)

Alfred is a long-time teacher and computer enthusiast who works with and troubleshoots a wide range of computing devices. The generations of computers illustrates the miniaturization of transistors and integrated circuit chips over the years. Generations of computers have seen changes based on evolving technologies. With each new generation, computer circuitry, size, and parts have been miniaturized, the processing and speed doubled, memory got larger, and usability and reliability improved. Note that the timeline specified for each generation is tentative and not definite.

Computers are such an integral part of our everyday life now most people take them and what they have added to life totally for granted. Even more so the generation who have grown from infancy within the global desktop and laptop revolution since the s. The history of the computer goes back several decades however and there are five definable generations of computers. Each generation is defined by a significant technological development that changes fundamentally how computers operate — leading to more compact, less expensive, but more powerful, efficient and robust machines. These early computers used vacuum tubes as circuitry and magnetic drums for memory. As a result they were enormous, literally taking up entire rooms and costing a fortune to run.

An amazing machine! We are living in the computer age today and most of our day to day activities cannot be accomplished without using computers. Sometimes knowingly and sometimes unknowingly we use computers. Computer has become an indispensable and multipurpose tool. We are breathing in the computer age and gradually computer has become such a desire necessity of life that it is difficult to imagine life without it. For most of the people, computer is a machine used for a calculation or a computation, but actually it is much more than that.

A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. A "complete" computer including the hardware , the operating system main software , and peripheral equipment required and used for "full" operation can be referred to as a computer system. This term may as well be used for a group of computers that are connected and work together, in particular a computer network or computer cluster.

Computer History: Classification of Generations of Computers

In particular, when viewing the movies you should look for two things: The progression in hardware representation of a bit of data: Vacuum Tubes s - one bit on the size of a thumb; Transistors s and s - one bit on the size of a fingernail; Integrated Circuits s and 70s - thousands of bits on the size of a hand Silicon computer chips s and on - millions of bits on the size of a finger nail. The progression of the ease of use of computers: Almost impossible to use except by very patient geniuses s ; Programmable by highly trained people only s and s ; Useable by just about anyone s and on. Mauchly and J.

How many generations of computers are there?

The history of computing hardware starting at is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit IC chips. Around - , discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive.

    Computer generations are based on when major technological changes in computers occurred, like the use of vacuum tubes, transistors, and the microprocessor.
