Computer evolution

Computers are the most useful and appreciable invention of humans till date. It has opened the doors to all kinds of technology that mankind sees now. Computers were basically invented to automate the mathematical calculations that were done by humans. In the industrial revolution, mechanical devices were made to automate the long and monotonous tasks. Charles Babbage is appreciated as the father of the computer.

Generations of computers are distributed into five generations, considering their technology. The fifth generation is the latest and most advanced of all of the generations. The computer is the most dominant invention of human history. The computer is used in government, banking, and education. It became necessary in scientific and political research, and moreover, in aspects of medicine and law.

The first generation of computers.

The first generation of computers was introduced in the mid-nineties. It was based on vaccume tubes for logic circuitry. The first computer that was introduced in the first generation of computers was the ENIAC (Electronic Numerical Integrator and Calculator), which was invented by Americans.

It was followed by Univac, which is by far the fastest computer in the world. The first generation of computers also had drawbacks as they were made with vacuum tubes that radiated a lot of heat, causing them to melt, resulting in high maintenance costs. It required a lot of space and air conditioning.

The second generation of computers

The second generation of computers was based on transistors instead of vacuum tubes. This generation of computers consisted circuit boards made up of transistors and magnetic core memory. These computers had low power consumption and it was smaller in size when compared to first generation computers. They also emitted less heat.

This generation of computers also had drawbacks. Although it generated less heat, it still required air conditioning. Its size was smaller relative to the first generation, but it still consumed a lot of space. It was expensive, and its production was difficult.

The third generation of computers

The third generation of computers used integrated circuits rather than transistors. The size of third generation computers was smaller than in previous generations. It used a magnetic storage device for storage. It had upgraded operations and more reliable outputs. It started the trend of using monitors and printers. Third-generation computers still needed air conditioning even though they generated less heat. Formal training was required to use the third-generation computers.


The fourth generation of computers

These computers used microprocessors and VLSI rather than IC. VLSI consists of thousands of transistors on a microchip. It used RAM and ROM for memory storage. It also supported high-level language. Advanced tech was required to build them, causing low production. A fan was necessary to keep the CPU cool.

The fifth generation of computers

The fifth generation of computers used ULSI. These computers were made by Japan. It also used artificial intelligence. It was advanced in parallel processing. Very powerful computers were available at cheap prices. It did not require formal training for usage. It had multimedia features and was more user-friendly. The drawback of fifth generation computers is that they can give increased power to companies to watch over what you are doing. It can also allow them to make changes to your computer.
