Which year was computer invented?

Answer 1

The first working computer was invented by an Englishman named Charles Babbage in the 1800s (1791-1871) but that followed the footsteps of Joseph-Marie Jacquard (1752-1834); who invented the punched card (for looms) and George Boole (1815-64) who invented the form of math (Boolean algebra) that allows computers to work.

There was little progress until WW II loomed and a need for gun trajectory calculations became important. Starting with relays (like the starter relay in your car) in 1936, Konrad Zuse built the first programmable computer of modern times.

Working for the Navy in 1942 John Atanasoff & Clifford Berry built the ABC computer using vacuum tubes. In 1946 Eckert & Mauchly built ENIAC with 20,000 vacuum tubes.

In 1951 they built UNIVAC, the first commercial computer.

Meanwhile, back in 1948 Bardeen, Brattain & Shockley invented the transistor.

In 1958 Kirby & Noyce invented (developed?) the integrated circuit.

In 1971 Faggin, Hoff & Mazor built the 4004 - the FIRST microprocessor.

In 1976 the Mark 8 Altair (as seen in War Games) and the IBM 5100 were built - the first consumer computers.

In 1976/77 we had the Apple I, the TSR-80, and the Commodore Pet. Mass market computers (although we had to wait till 1979 for the Apple II).

1974

Answer 2

The computer was not invented in any one year because so many people were working on different computers at the same time. It is believed that the first computers were built as early as the 1940s.

Answer 3

• The first known analog computer was invented circa 100BC.
• The first digital computer was invented in 1838, but was never built.
• The first electronic digital computer was invented in 1936 and finished in 1942. Soon after it was finished it was destroyed because it had been built too wide to fit through a doorway, the university where it was built needed to convert the space to classrooms, and its inventors had left to perform war related work.
• The first programmable electronic digital computer was invented in 1943 and 10 of them were built between 1944 and 1945. All but 2 were destroyed in 1945, due to their classified nature and the end of WW2. The last 2 were destroyed in the early 1960s, along with all remaining documentation.
• The first modern electronic digital computer was invented sometime between 1943 and 1945 on Project PX (the project that built ENIAC). The invention was not used on ENIAC. The first computer to use this invention was a prototype computer called the Manchester Baby, built in 1948.

Answer 4

Some might say that the Babbage Difference Engine was the first computer. It was built in 1822. The first programmable computer was the Z1 built in Germany in 1938. The Colossus was the first electric computer in 1943. The Atanasoff-Berry Computer was the first digital computer in 1937. ENIAC was completed in 1946. IBM built their first mainframe in 1953. The first mincomputer was built in 1960. Hewlett Packard built the first desktop computer in 1968 called the HP9100A.

Answer 5

The computer was invented in 1833. The inventor was Charles Babbage. He was unable to complete the machine, but his son completed it for him in 1888.

Answer 6

The Abacus, which has Chinese, Japanese, and even Russian ( T"choty) variants is in a sense the ancestor of all mechanical computing devices. It is ancient.

Answer 7

No-one Knows. It must have been around 4000BC because as far as I know the abacus was like a computer and it was invented around 4000BC.
