What did the first computers perform?
The first computer was an Chinese abacus.
A computer is defined as A device that computes that assembles, stores, correlates, or otherwise processes information.
An abacus is a manual computing device consisting of a frame holding parallel rods strung with movable counters.
Word History: The adjective dusty, with its connotations of disuse and age, might seem an appropriate word to describe the abacus, since this counting device was used for solving arithmetical problems in the days before calculators and computers. Originally the abacus was, in fact, dusty. The source of our word abacus, the Greek word abax, probably comes from Hebrew 'bq, "dust," although the details of transmission are obscure. In postbiblical usage 'bq meant "sand used as a writing surface." The Greek word abax has as one of its senses "a board sprinkled with sand or dust for drawing geometric diagrams." This board is a relative of the abacus with movable counters strung on rods that is familiar to us. The first use of the word abacus, recorded in Middle English in a work written before 1387, refers to a sand-board abacus used by the Arabs. The difference in form between the Middle English word abacus and its Greek source abax is explained by the fact that Middle English borrowed Latin abacus, which came from the Greek genitive form (abakos) of abax.

The first scanner for computers was introduced in the year 1957. It was a drum scanner that was designed by Russell A. Kirsch.
What was the first digital computer named?
"In the year 1837, Charles Babbage was the first to think about something that would function like a computer and ended up designing a programmable mechanical computer that he called "The Analytical Engine" "
" Then Konrad Zuse came in the whole arena in the year 1941. He also wanted to make something that would be like a computer hence was created electromechanical "Z machines," the Z3, which was the first working machine, which featured binary arithmetic, including floating point arithmetic and a measure of programmability. "
"The Sphere I was completed in 1975 by Michael Donald Wise (1949-2002), founder of Sphere Corporation, of Bountiful, Utah. The Sphere I featured a Motorola 6800 CPU, onboard ROM, Monitor, 4 KB of RAM, and a keyboard with a numeric keypad Sphere 1 was acknowledged as the first true Personal Computer"
What was the first used computer by the census bureau?
A UNIVAC I computer was accepted by the Bureau in 1951
Why is the keyboard called the Qwerty keyboard?
It was originally laid out like it is to take allow the strongest fingers to be in contact with the most commonly used keys. The QWERTY keyboard layout was specifically invented, around the turn of the century, after studies on the English language, to be counterproductive, i.e. to make users type as slowly as possible. This was needed because the old, mechanical, typewriters would jam if the user was typing too fast.
What year was the computer made?
- John Vincent Atanasoff and his assistant Clifford Berry built ABC, the first electronic digital computer (a special purpose machine that was not programmable) from 1936 to 1942. The local newspaper in Ames, Iowa where it was built published an article on it in 1941.
- Tommy Flowers and a team in the British Post Office built Colossus, the first programmable electronic digital computer from late 1943 to June 5, 1944 to break the Nazi high command's cyphers, just in time for D-day. Before the end of the war a total of 10 Colossus computers were built in 2 different models. Colossus remained classified until after 1980, so it does not appear in most computer histories.
- J. Presper Eckert, John Mauchly, and a team of several hundred engineers, technicians, and assemblers built the ENIAC, the first general purpose programmable electronic digital computer from 1943 to November 1945. Its first real program took 2 months to run (December 1945 to January 1946) and simulated Edward Teller's first hydrogen bomb design (proving it unworkable). ENIAC was declassified and announced to the public in February 1946 (the first computer to receive nationwide publicity).
What was the name of the first computer made by Apple that had a graphical interface?
The first one they built was the Apple I, a machine running the MOSTEK 6502 microprocessor.
The first computer that Steve used, I don't know.
Who developed the first operating system?
None, early computers had NO operating system. Jobs were manually loaded and run either by the programmer or a computer operator, one at a time.
By the middle 1950s some companies began to realize the economic inefficiency of this, with computer time costing around $1000 per hour, of having the machine sit idle while the operator slowly set up the next job. This prompted these companies to write the first Batch Monitors. While not yet true operating systems, they allowed a computer operator to prepare a batch of jobs (e.g. dozens to hundreds) and set them all up on the computer once, then the Batch Monitor program would automatically load and run each job one at a time in the sequence they appeared in the batch. Meanwhile the operator could be separating listings from the previous batch, preparing the next batch, etc. This produced much more efficient use of both the computer's and the operator's time. Often these companies donated these Batch Monitors (and other utilities) to the Users Group library supported by the manufacturer of the computer they had. Other companies could get this software and improve on it (early Freeware).
One of the first manufacturer supported Batch Monitors (actually very nearly an operating system but still not quite) evolved this way from a Batch Monitor written by a customer and donated to the Users Group: IBM's IBSYS for the IBM 709, 7090, and 7094. Based on FMS (written by IBM, could only run FORTRAN jobs) and SOS (written by General Motors), IBM released it to customers in 1960 (2 years after the IBM 7090).
What we now call operating systems only began to appear in the middle to late 1960s, on 3rd generation computers being used for dial-up multiuser tymesharing. These systems could simultaneously run both Batch and many Interactive jobs.
Early microcomputers of the 1970s also lacked operating systems. The first microcomputer operating system was Gary Kildall's CP/M (based on a DEC PDP-8 operating system) for the Intel 8080. Originally written to help him develop the PL/M compiler for Intel, when he offered them CP/M too, they turned him down saying "we are a chip maker, not a computer company, we don't need it". Eventually they realized they did need it, so they developed ISIS.
MSDOS was based on a CP/M clone called QDOS: Quick and Dirty Operating System.

Impacts of and internet on education?
The Internet has exponentially improved the speed at which information may be disseminated to remote places all over the world, enhancing collaborative learning. It has also introduced new modes of education such as e-learning.
The first graphical browser for the WWW was named?
the First Described Web Browser was the Mosaic : It was derived from a collection of independent works by people that was organized into one actual product.
Dr. Douglas C. Engelbart , Tim Berners-Lee , are credited with the Foundations for what later became the Mosaic and later called the NCSA Mosaic :
The NCSA Mosaic 1992.
Marc Andreessen,started Netscape, and released the Mosaic-influenced Netscape Navigator in 1994,

When did the first computer come out to public?
the first computer was available in1950 the first computer was available in1950
Who made the first commercial computer?
The first computer, called UNIVAC, was designed by Eckert-Mauchly Computer Corporation and was completed by Remington Rand in 1951. There would have been several projects running in parallel. Lyons (who made cakes and ran teashops) sponsored Cambridge university to build EDSAC (first program run in 1949), this was intended to prove the concept of a business computer. Following this its successor LEO went into production use in 1951. Lyons went on sell LEOs and provide an outsourcing facility but ultimately they were a cake maker not an IT company so they merged the LEO business with EEC. So you could argue that EDSAC was the first commercial computer running in 1949
Are there real assassins today and where are they?
like off assassins creed,yes but I keep looking for them and still it's hard. i can tell u this stop looking because u will never find our guild im am a assassin and if u do find us we will find u
How much did a mini computer cost in 1962?
It didn't cost anything, because there weren't any minicomputers in 1962. IBM released their first mini, the 1130, in 1965, and it cost, according to IBM, $32,280. Obviously that number was picked by an accountant instead of the programmers. Check it out: the 1130 was a 16-bit computer, and the largest 16-bit number is 16,384. A programmer would have chosen $32,768--twice 16,384--as the computer's price.
Was the computer invented in 1890s?
Sorry, I made a mistake and I hope I did not case you trouble.
There is a big line when we define a computer, it is not like we look at out computers today. Something making a calculation can be a computer.
The first computer, which is on display, and called a computer, was invented
in 1847 by Charles Babbage.
This question has been answered before on wiki answers, and the page is very long depending on what class is considered a computer, so as it seems it would have to be asked by what class of computer to get the right answer.
What is a mini computer used for?
The wonderful thing about mini computers is that they can be used just about anywhere. Long battery life allows the unit to be used at the beach, at the pool, or anywhere where power is not available.
Who made the first electronic computer?
Several electronic analog computers were made in the 1930s.
The first electronic digital computer was the Atanasoff-Berry Computer (ABC) in early 1942, it worked (except for intermittent problems in the high speed "card" reader/punch) but was abandoned soon after when the two people working on it left for war work.
The next electronic digital computer was the Colossus a prototype of which was built in December 1943 and the first production unit went into operation in June 1944 just in time to crack critical German messages that were used by the Allied generals to commit to the D-Day landings despite very bad weather conditions. Unfortunately these computers (the only ones built in a quantity greater than one until Univac in 1952) remained classified until the early 1980s and so do not appear in most histories of computing.
The first well known electronic digital computer was the Electronic Numerical Integrator And Computer (ENIAC) in November 1945 and announced to the public in February 1946.
