The evolution of computers has been drastic and dramatic. Computers have been around since the early 1950s, but people couldn’t use them. When you mention the word computer, most people only think of the desktop computer, but actually the computer starts with our calculator.
Therefore, a computer can be defined as an electronic device that inputs, processes and outputs information. Let’s take in the case of a calculator, when you add figures, you are example 1+1 = 2, now you will enter data that is 1+1, this data will be processed through the addition process, to give us 2. Now 2 is the data of the process that is the output.
The first computers that were invented were very large, slow and time consuming with limited capabilities. The history of computers has gone through various stages as they evolve, starting with the first computers, before the first generation computers, we had the ABACUS computers, which were limited by their capabilities.
The first generation was developed in the early 1940s with its architect based on massive electronic value. They depended on the vacuum tube and without it they would not work, from the first generation computers came the second generation computers that were better than the first generation computers at performing electronic calculations but were still slow, an example of this second generation was the series ABM7000.
As the computer kept evolving in generations, people got more knowledge about them and the invention kept getting better, because of this, the third generation of computers was made, these generations of computers were more powerful than the first and second computers generation, and use integrated circuits normally. known as IC. An example of third generation computers was the IBM 360 Series.
The third generation computers led to the fourth generation in computer history, with this generation, the electronic function was better, more efficient and more enjoyable with relatively fewer bugs compared to the previous computer. And these are the computers that we use in our day to day. They also use integrated IC circuits for their daily operation. The fourth generation computer will lead to the fifth generation computer, which will be more powerful and have the ability to take instructions from people. This is known as artificial intelligence, in some cases robots are used to perform certain jobs that were previously done by humans.
