Computers have seen significant changes and development over time. Each generation of computers brought about significant technological advancements as well as some significant design changes.

In the past, grandchildren had to make long trips to visit their grandparents.

With today’s highly advanced cellphones and laptops, the scenario is different. To better understand the history of computer innovation and development, let’s delve further and learn about the “Five Computer Generations.”

Five Computer Generations

The First Generation, 1940–1956

These computers were built to be bulky.

Punch cards were employed to input additional data. About consuming a significant amount of electricity, they were costly to operate and produced a lot of temperatures. Additionally, it took up a lot of room. These machines employ assembly language and machine labour.

Examples of those computers include IBM 650, 702, 705, Mark II, ENIAC, EDVAC, EDSAC, and UNIVAC.

The Second Generation, 1956 – 1963

This Generation’s computer was constructed from transistors, which involved swapping out the vacuum tube. This vacuum tube quickly outperformed the computers of the second Generation. They were pretty minor compared to the first generation. The machine required less room and operated much more quickly by employing transistors.

This reduced the size of computers. Relative to the first generation stage, faster, more straightforward, better impact effectiveness, and more dependable transistor steel produced a lot of heat. 

Punched cards for input and output made it easy to disable high-level language cassettes like FORTRAN, COBOL, and BASIC for output. This computer used transistors instead of valves, which produced heat insignificantly and were relatively small.

IBM 700, 1401, 1620, 7064, CDC1604, 3600, RCA 501, UNIVAC 1108, Leonard 111, ATLAS, and ICL were the brands of the computers.

The Third Generation, 1964 – 1971

Integrated circuits were used to build numerous computer generations—an efficient and effective system. There were one hundred transistors on a silicon chip, where the steel was thinner than in second-generation computers.

It produced a small number of message hits as well. It quickly occupied less area after that. Third-generation computers employed keyboards and monitors to interface with punch cards and printers.

Also, it had an operating system interface. It enabled the gadget to run the center software and several other apps. Because they were insignificant and inexpensive, it wasn’t easy to attract a large audience.

The Fourth Generation, 1971 – 1980

With the development of integrated circuits on a big scale, computers’ sizes started to shrink as technology advanced.

Additionally, the ultra-large size allowed the integration of millions of components into a tiny chip. As a result, the computer got smaller and less expensive.

The 1971-developed Intel 4004 device advanced Integrated Circuits 1 by addressing all of a computer’s central processor unit, memory, and input and output control on a tiny chip, in addition to improving power efficiency and durability.

The average user could use the computing power in a compact area. The first computers were minicomputers, which provided users with a range of tools, the most well-known of which were word processors and blank sheets.

Which video game systems that non-technical users can use? IBM released personal computers for home and workplace usage in 1981, much like the Atari 26 200 sparked computer interest among the general public. As time went on, however, computer size became smaller.

It won’t collapse. Throwing the laptop, and workstation, aside, a graphical user interface for the Macintosh eliminated the need for the user to enter instructions.

However, where continual innovation enabled the linking of machines to exchange information in local area networks and wide area networks, the mouse for this function became a potential benefit.

The Fifth Generation, 1980 & Above

A different category of a computer with powerful computational speed and parallelism based on developing microelectronics technology got released in the 1980s, the fifth Generation.

Leo was the technology being developed which was highly integrated and large-scale. This could incorporate a lot more circuits into a single integrated circuit.

It is feasible, and advancements in computer hardware and software design result in computers that are much more potent than those in use today. It is anticipated that a computer of this kind will be able to speak naturally to the customer store.

The parallel interface would have human-like cognition and behavior. As a result, this synthetic brain would represent one of the most compelling examples of a computer-style cognitive processing system. This computer will complete each task autonomously and on schedule thanks to its artificial brain.


Children should perform better in talent development and learning activities and be more beneficial or successful in numerous sectors when they understand how computers work the more advanced the computer technology.

Children involved in utilizing computers to develop technological projects become more accustomed to the technology and are, therefore, more likely to acquire new technologies more quickly.
