Only one ENIAC was ever built. Its mechanism of programming was too inefficient and error prone.

How many vacuum tubes in first generation computer?
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
What is the first considered minicomputer?
Many computer historians consider the DEC PDP-1 to be the first minicomputer, but it was still quite large and was built entirely with discrete transistors. Most computer historians consider the DEC PDP-8 to be the first minicomputer as it was actually small enough to sit on a desk and later models were built with monolithic integrated circuits.
Which year was computer invented?
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
What was the name of the first commercial electronic digital computer?
The first electronic computer invented was the Atanasoff Berry Computer. It was a special purpose computer designed only to solve simultaneous equations of up to 29 variables. The central concepts common in modern computers that it embodied were:Dynamic memory storage using refreshSeparation of arithmetic unit from memory unitBinary twos-complement signed numbersIt was completed and operating in 1942. It was also the world's first vector/array processor, having a vector register length of 30 words 50 bits long and 2 vector registers. Vector registers are used in many supercomputers and high performance microprocessors to do the same operation on many different numbers at the same time.
In what country was the computer invented?
The first electornic computer was built in the United States, to solve ballistics problems. It was called ENIAC, and was completed in 1946. The program was wired into the computer, which used several hundred vacumn tubes.

Which came first communication or computer?
Humans have been communicating with each other in many different ways for several hundred thousand years.The first digital computer was invented in the 1830s by Charles Babbage but never built. The first electronic digital computers were invented in the 1930s and built in the 1940s. Electronic digital computers did not become a marketed product until the 1950s.
What are some common accessories for a computer monitor?
One of the most common accessories for computer monitors are webcams. Many monitors have them built right into them nowadays. As well, built-in speakers are also very common.

Was Mark1 computer was invented after the Apple Newton or before?
The term Mark I Computer is ambiguous as there were many given this name built in different places by different people. However as almost all of these computers were first generation machines (using vacuum tubes) built before 1960, it is probably safe to say the Mark I Computer was before the Apple Newton.

Where found computer blutooth device?
Most recent notebooks have them built in, and many cell phones do.
Did dell make the first computer?
no!the first electronic digital computer was made by Dr. John Vincent Atanasoff and his graduate student Clifford Berry at Ames Iowa, in 1942.the first programmable electronic digital computer was made by Tommy Flowers and the british post office technicians of Dolis Hill Research Station, in 1944.the first stored program computer was made at the Victoria University of Manchester by Frederic C. Williams, Tom Kilburn and Geoff Tootill, in 1948.the first transistorized computers were made in the late 1950s, by various companies and universities.the first computers built with integrated circuits were made in the early 1960s, by various companies and universities.the first computer microprocessor integrated circuit was made by Intel, in 1971. This resulted in an avalanche of microprocessor based inexpensive computers throughout the 1970s.the first IBM PC was made by IBM, in 1981. Many PC clones appeared in the next few years.the first Dell computer (a clone of the IBM PC), was made in 1985.Electronic digital computer had been built for 43 years before the first Dell computer. Dell can't even take credit as the first IBM PC clone. Prior to digital computers there were analog computers of many different types. There are so many I could not begin to give any reasonable list of firsts. The period of the 1920s through 1930s saw the largest expansion in new types of analog computers.The first known mechanical analog computer was built circa 100BC, by the Greeks.
