when were computers invented and by whom?

We could argue that the first computer was the abacus or its descendant, the slide rule, invented by William Oughtred in 1622. But the first computer resembling today's modern machines was the Analytical Engine, a device conceived and designed by British mathematician Charles Babbage between 1833 and 1871.

Explanation: A computer is a machine made up of parts for the hardware and software. Based on the instructions given, a computer receives data through an input unit and sends it back through an output system after it processes the data. The input devices of a computer are used to get the input data.

The term "information technology" evolved in the 1970s. Its basic concept, however, can be traced to the World War II alliance of the military and industry in the development of electronics, computers, and information theory.

Bill Gates got an early start to building his fortune. At just 17, he sold his first computer program, a timetabling system, to his private high school for $4,200. Childhood friends, Bill Gates and Paul Allen founded Microsoft in 1975. In 1980, Microsoft developed an operating system for IBM's first personal computer.

They first appeared in 1971. First generation computers are those that used either relays or vacuum tubes (1940–1956). ... Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today.

Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. ... It was called the Atanasoff-Berry Computer (ABC) ...

Atanasoff-Berry Computer (ABC), an early digital computer. It was generally believed that the first electronic digital computers were the Colossus, built in England in 1943, and the ENIAC, built in the United States in 1945.

The early computers were made to calculate large amounts of arithmetic data and tally. Alan Turing's computers cracker secret codes. Computers were used for surveys and scientific help too. Early computational devices tended to be analogue rather than digital.

The laptop was invented by Adam Osborne in 1981. It was called ''Osborne 1'' and cost $1,795. It came bundled with $1,500 worth of programmes. It had a tiny computer screen built into it.

In common usage, "microcomputer" has been largely supplanted by the term "personal computer" or "PC", which specifies a computer that has been designed to be used by one individual at a time, a term first coined in 1959.

The invention of the transistor was one of the most important developments leading to the personal computer revolution. The transistor was invented in 1947 and announced in 1948 by Bell Laboratory engineers John Bardeen and Walter Brattain.

A Turing machine is the original idealized model of a computer, invented by Alan Turing in 1936. Turing machines are equivalent to modern electronic computers at a certain theoretical level, but differ in many details. ... The prize Turing machine has two possible states of its head, and three possible colors on its tape.

A microcomputer is a complete computer on a small scale, designed for use by one person at a time. An antiquated term, a microcomputer is now primarily called a personal computer (PC), or a device based on a single-chip microprocessor. Common microcomputers include laptops and desktops.

In Celebration of Ada Lovelace, the First Computer Programmer. The first programmable computer—if it were built—would have been a gigantic, mechanical thing clunking along with gears and levers and punch cards. That was the vision for Analytical Engine devised by British inventor Charles Babbage in 1837.
