What is history of computer and its generation?

1st Generation: This was from the period of 1940 to 1955. This was when machine language was developed for the use of computers. They used vacuum tubes for the circuitry. 3rd Generation: The hallmark of this period (1964-1971) was the development of the integrated circuit.

What are the history of computers?

Charles Babbage, an English mechanical engineer and polymath, originated the concept of a programmable computer. Considered the “father of the computer”, he conceptualized and invented the first mechanical computer in the early 19th century. The machine was about a century ahead of its time.

What is the history of computer in short?

In the early 1820s, it was designed by Charles Babbage who is known as “Father of Modern Computer”. It was a mechanical computer which could perform simple calculations. It was a steam driven calculating machine designed to solve tables of numbers like logarithm tables.

What is the history of modern computer?

The first modern computers. The World War II years were a crucial period in the history of computing, when powerful gargantuan computers began to appear. The first large-scale digital computer of this kind appeared in 1944 at Harvard University, built by mathematician Howard Aiken (1900–1973).

What is the name of first generation computer?

vacuum tubes are known as first-generation computers. (With 1,500 mechanical relays, ENIAC was still transitional to later, fully electronic computers.)

What year was the first computer made?

1943
The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946.

Who built the first modern computer?

Charles Babbage
Computer/Inventors

What are the features of a first generation computer?

Year Built. Most computer historians consider the first generation of computers to include machines that were built between 1946 and 1959.

What are the different generations of computer?

Generations of Computers and Their Characteristics. Generations of Computers can be generalized into mainly five generation : 1. First Generation Computers –1942 to 1954 2. Second Generation of Computers -1955 to 1964 3. Third Generation of Computers- 1965 to 1974 4. Fourth Generation Computers- 1975– till now 5. Fifth Generation of Computers – Still in Process.

What is the second generation computer?

IBM 1620. A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes.
