- What is the history of computer
- Hi! Today I'll tell you the history of computers.
- The history of computers goes back over 200 years. At first theorized by mathematicians and entrepreneurs, during the 19th century mechanical calculating machines were designed and built to solve the increasingly complex number-crunching challenges. The advancement of technology enabled ever more-complex computers by the early 20th century, and computers became larger and more powerful.
- Today, computers are almost unrecognizable from designs of the 19th century, such as Charles Babbage's Analytical Engine — or even from the huge computers of the 20th century that occupied whole rooms, such as the Electronic Numerical Integrator and Calculator.
- When was the first generation of computer
- The period of first generation of was from 1946-1959. The computer of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit).
- ENIAC (Electronic Numerical integratorand computer) known as the first operational electronic general purpose computer. it was built in 1946.
- In 1918, two scientists (Eccles and Jordan) use vacuum tube amplifiers to produce a train. In 1939, a prototype of theAtanasoff-Berry computer was created which is called the first computer vacuum
- In 1942, an experimental electronic computer circuit was made with 100 tubes, but this circuit was destroyed in an air raid. in 1945, a system computer was developed in the united states called ENIAC computer.
- An integrated circuit is a small chips that was the trademark of the computers of third generation. The integrated circuit used in 3rd generation computers can work as a computer memory, microprocessor or even an amplifier .
- The first to develop the idea of the integrated circuit was Robert Noyce of Fairchild Semiconductor and Jack Kilby (American Electrical Engineer) of texas instrument in 1959.
- The third generation of computers used integrated circuits instead of transistors technology that was used in computers of second-generation. its time period was around 1964 to 1970.
- the fourth generation of computers had characteristics linked with the process of building an integrated circuit (IC) by merging numerous transistors into a single chip. Fourth-generation computers, For example, fourth-generation computers were more adaptable, had a larger primary storage capacity, were faster and more reliable, were portable, were very compact and small, and so on, thanks to the technology utilized to make them.
- Fourth generation of computer (1972 on ward) VLSI (Very Large Scale Integrated) Circuit they're additionally referred to as microprocessors are utilized in this generation.
- As a result, these computers were small and only required a small amount of electricity to operate.
