Each Accumulator could do 5000 additions or subtractions per second and there were 20 Accumulators that could potentially all run simultaneously if the problem could be setup with enough parallelism (which was difficult to do and thus rare, even when it could be done it was impossible to sustain for long).
The theoretical ideal case speed (with full parallelism) was 5000 * 20 = 100,000 additions or subtractions per second.
What was the first computer used for calculation?
The first computer used for calculation is highly dependent on what you consider a computer to be. In many views, the first computer used for calculations was the abacus which dates back to 2400 BC.
Where is the computer on a 97 cavalier?
Remove your glovebox, and you will see it
Its located right behind the glovebox.
According to the CIA World Factbook estimated, as of 2005, there were 1,018,057,389 internet users worldwide.
When people began to develop the ENIAC?
Atanasoff's Computer was nearly completed in 1942 before Atanasoff and his assistant were drafted. This Atanasoff was the first to think of using base 2 (or binary) in his mechanical computation and incorporated that into his computer. However, a friend of Atanasoff's is believed to have visited while the computer was still in production and later used the knowledge gained from that visit while helping to build ENIAC a few years later.
Why is it personality important?
There can be many causes. A few of them are:
a mental disorded
stressed home life
and insicurity about one's self
How is data stored on a CD-ROM?
Data is recorded onto a CD in a clockwise spiral from the center. Its recorded and read in a series of lands and pits. Any land that the laser hits is reflected to the read head and is recorded as a 1 or a 0. They are counted in groups of 14 and then converted into standard 8-digit data.
A CD is built from a plastic (polycarbonate) substrate and a fine, reflective metallic film (24-carat gold or a silver alloy). The reflective layer is then covered with an anti-UV acrylic finish, creating a protective surface for data. Finally, an additional layer may be added so that data can be written on the other side of the CD as well.
The reflective layer contains tiny bumps. When the laser passes over the polycarbonate substrate, light is reflected off the reflective surface, but when the laser reaches a bump, that's what allows it to encode information.
This information is stored in 22188 tracks engraved in grooves (though it's actually just one track spiralling inward).
Commercially purchased CDs have already been pressed, meaning that the bumps have been created used plastic injected into a mold which contains the desired pattern in reverse. A metallic layer is then affixed onto the polycarbonate substrate, and this layer is itself covered with a protective coating.
Microsoft early start began in Albuquerque, NM in March 1975. Microsoft is headquartered in Redmond, Washington, 13 miles from Seattle.
What are features for second generation computer?
Second generation computers are often called transistorized computers. The transistorized computers are more advanced computers than the first generation of computers.
What company sold or made the first laptop IBM or HPor Toshiba?
Macintosh PowerBook 100,
by Apple.
in the early 90s.

What is the main difference of a Dvorak keyboard and a qwerty keyboard?
letter placement on keyboard
QWERTY was simply laid out to reduce probability of hammer clashes.
Dvorak was laid out to put most frequently used letters on keys under strongest fingers.
How much do you make working at IBM?
The computer brand IBM makes a year comes to over 150 million a year subtracting rent, taxes and etc. which makes the profit come to about 12 million.
What features were the first home computers limited to?
The first home computers could do anything any other computer could, if you could fit it in their tiny memories.
However the first electronic computers in the 1940s and 1950s had exactly the same problem, very tiny memories.
In each of the 5 generations what was the cause for the increase of speed power or memory?
Improved technology
Which word processor came first?
The first word processing program was called FORMAT. This program was written by Gerald M. Berns and produced by IBM in the late 1960s.
The SMS concept was developed in the Franco-German GSM cooperation in 1984 by Friedhelm Hillebrand and Bernard Ghillebaert.
Which year the Mini computer been invented?
Mini computers are smaller computers that sell for much less than regular computers. The first mini computers were produced in the Soviet Union from 1958 to 1962.
Did a black man invent the computer?
The world's first computer is the Antikythera computer, which was from Ancient Greece.
First programmable computer
The Z1 originally created by Germany's Konrad Zuse in his parents living room in 1936 to 1938 is considered to be the first electrical binary programmable computer.
The first digital computer
Short for Atanasoff-Berry Computer, the ABCstarted being developed by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937 and continued to be developed until 1942 at the Iowa State College (now Iowa State University). On October 19, 1973, US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic digital computer.
What year did the computer come out?
- Analog computers were developed in the late 1920s.
- Digital computers were developed in the early 1940s.
Which ATA standard is the latest standard that made improvements to PATA?
ATAPI 8 is the answer you're looking for, not the most recent, but it was at the time the A+ book with this question was published
