History of the Computer

The word computer first appeared in 1613, which means calculation. Charles Babbage designed the first computer in the early 19th century, designed the analytical engine, and designed the basic computer framework. The creation of computers has been progressed further on this framework. By the way, computers have been developed in three generations, every generation was of a certain duration. We have got a better, new computer after every generation of development.

Between 1937-1946 In 1937 the first digital computer was built by Dr. John V. Atanasoff and Clifford Ber. It was named Atanasoff – Berry Computer (ABC). In 1943, this electronic computer was named Colossus, which was made for the military. Further work continued until 1946 and digital computers and numerical integrator computers (ENIAC) were made. It is said that the weight of this computer was 30 tons, 18 thousand vacuum tubes were used for processing in it. Computers of this time we’re able to do only one thing at a time, as well as there was no operating system in it.

Between 1947 –1962 computers of this time used transistors in place of more reliable vacuum tubes. For the first time in 1951, the computer was put in front of the public, and its use was made public. In 1953 IBM made 650 and 700 series computers. About 100 types of programming languages ​​were developed in this time computer, as well as memory and operating system. There was tape, a disk for storage, as well as printers, were attached to the computer.

1963 – To Date Integrated circuits produced the third generation of computers. With this genesis, the size of the computer became smaller, it became more powerful and reliable, with these people could now do a lot of work on the computer at one time. MS-DOS was created in 1980. In 1981, IBM brought personal computers to the home and office. Three years later, Apple built a Mac computer, and in the 90s the computer got the Windows operating system.

What is Cloud Computing? What Are the Advantages of it?

Today the computer is progressing day by day, a lot of programming language has arrived, through which work is done. Instead of computers, laptops have come, which are small and less in weight, it has OS, battery and everything. Computers were kept in one corner of the house, office, it was difficult to take them here and there, but the laptop started to be used anywhere.
