The main electronic components that are used in the present generation of computers is Artificial Intelligence which uses the parallel processing method and the Ultra-Large Scale Integration (ULSI). The Fifth Generation of Computers- (present and the future) The input/output devices are a monitor, mouse, keyboard, printer, and so on.Įxamples are STAR 1000, APPLE II, IBM PC, and so on. The sizes are smaller and the speed has improved. High-level languages such as C#, JAVA, Python, JavaScript are used as programming languages. ROM (read-only memory)- Permanently stores the data and programs and the contents are retained even after shutting down the computer. RAM (random-access memory)- Temporarily stores the programs and data and the contents are lost when the computer is shut down. Semiconductor memory storage units such as RAM, ROM, etc were introduced. When thousands of transistors are attached to a single microchip, it is known as VLSI. The main electronic components used in the fourth generation of computers are microprocessors and very large scale integration (VLSI). The Fourth Generation of Computers- (1970s-present) The input/output devices were keyboards, magnetic tape monitor, printer, etc.Įxamples are IBM 370, IBM 360, UNIVAC 1108 and so on. There was an improvement in reliability and speed as compared to the second generation of computers. The sizes were smaller and efficient and the computers were called minicomputers. High-level languages such as BASIC, COBOL, Pascal were used as the programming language. The memory storing units were the magnetic disk or take and a large magnetic core. The main electronic components used in the computers of the era 1060s to 1970s were integrated circuits ICs. The Third Generation of Computers- (the 1960s-1970s) The input/output devices were magnetic tape and punched cards.Įxamples are IBM 1401, IBM 7094 AND IBM 7090, UNIVAC 1107, and so on. The sizes were smaller as compared to those of the first generation and they used to consume low power and generate less heat. The assembly language was used as the programming language. The main memory storing units were magnetic tape or disk and magnetic core. The main electronic component used in the computers of the 1950s to 1960s era were transistors. The Second Generation of Computers- (the 1950s-1960s) The only input/output devices were paper tape and punched cards.Īround 100 different vacuum tubes were used in order to produce the computers.Įxamples are UNIVAC1, ENIAC, IBM 701 and IBM 650, etc. The sizes used to be very large which could take up entire rooms and the speed was very slow. The machine language was used as the programming language. The main memory storing units were magnetic tapes and magnetic drums. The main electronic component used in the computers of the 1940s to 1950s era were vacuum tubes. The First Generation of Computers- (the 1940s-1950s) The Generation of Computer Evolution is Generally Divided Into 5 Categories. Before we jump on to the details, it is important to go through an overview of these generations. In the rest of the article, we will discuss these five computer generations.

However, these days, generation can be used to refer to both software and hardware these together form the entire computer system. Earlier, the term generation was used to differentiate between different hardware technologies. This term refers to the change that a computer goes through. In the field of electronics and technology, generation is computer terminology. As of now, there are five generations of computers. Since then, experts have also developed other generations of computers. At that time, the first generation of computers was created. You might also be interested to know that the evolution of computers began sometime during the 1940s. One can also use these devices to create or edit presentations, spreadsheets and videos. These days, people use computers for typing documents, playing games, sending emails and browsing the internet. Computers also have the ability to store, retrieve and process information. According to experts, a computer can be defined as an electronic device used for manipulating information or data. Let’s first begin with what the meaning of computers is. In this article, we will answer both of these questions in great detail. If you are curious to know the answer to these questions, that is great. Have you ever wondered what a computer really is? Do you know what the generation of computers is?

There are also pretty good chances that you still use a computer daily. Computers are essential devices that you must have used while growing up.
