First generation The period of the first generation: 1946 -1959. Vacuum-based tube.
Introducing yourself Hello. Good to see you all. I am Botakul Bakdaulet wanted to show your presentation.
Introducing the topic Today I am going to tell you about the period of first generation: 1946 -1959. Vacuum tube based.
Generation in computer terminology is a change in technology / computer was used. Originally, the term was used to distinguish the generation of various hardware technologies. But in our time, generation includes both hardware and software, which together make up the whole computer system.
◦ There are totally five computer generations hitherto known. Each generation has been discussed in detail, along with their characteristics, and the time period. Here are the approximate dates against each generation have been mentioned, which are generally accepted.
Below are the top five generations of computers. First generation The period of the first generation: 1946 -1959. Vacuum-based tube. second generation The period of the second generation: 1959 -1965. Transistor-based. third generation The period of the third generation: 1965 -1971. The integrated circuit on the substrate Fourth generation fourth generation period: 1971 -1980. VLSI microprocessor based. Fifth generation The period of the fifth generation: the 1980 year. ULSI microprocessor
First generation The period of the first generation: 1946 -1959. Vacuum-based tube. first generation period was 1946 -1959. the first generation of computers used vacuum tubes as the main components, and memory circuits for CPU (Central Processing Unit). These tubes, such as light bulbs, made a lot of heat, and were prone to frequent melting units, so were very expensive and could afford only very large organizations. In this generation it has been mainly used in batch processing operating system data. Punched cards, magnetic tapes and paper tapes were used as input and output devices. Computers in this generation of machine code used as the programming language.
The main features of the first generation are: The technology of vacuum tube unreliable Supported only machine language Very expensive Formed a lot of heat Slow input and output device huge size The need for AC non-portable It consumes a lot of electricity
Some computers of this generation were ENIAC EDVAC UNIVAC IBM-701 IBM-
Thanks very much.
