Why was the Atanasoff-Berry computer invented?
Because Dr. John Vincent Atanasoff had too many physics problems to solve that required the calculation of systems of simultaneous equations that were much too large for the manual methods of the time using either slide rules or mechanical desk calculators.
What was the computer used for before the internet?
The same as modern computers! Word processing, spreadsheets, games, photo storage, desktop publishing, graphic drawing etc - in fact anything that modern computers are used for except things specific to the internet (like email, webcams, surfing websites etc)
When and who developed the first email program?
A binary number is a number that consists of only 0 and 1. We use decimal numbers, which consist of numbers made up from 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The decimal system is also known as the denary system. Binary is critical to how computers operate, but that would take time to explain in detail. For your examples that you asked for, the following is how binary and decimal represent numbers from decimal 0 to decimal 10.
0 = 0
1 = 1
10 = 2
11 = 3
100 = 4
101 = 5
110 = 6
111 = 7
1000 = 8
1001 = 9
1010 = 10
What are the operations performed by the CPU?

What year was the electronic computer invented?
1937, in an Indiana bar by Dr. John Vincent Atanasoff. He and Clifford Berry finished building it in early 1942 but after they left Iowa State University to perform war related work, the machine was soon scrapped when the room it was in needed to be converted to classrooms and the machine was found to be too wide to roll it out through the door.
How is analog computers are more powerful then digital computers?
- Digital computer uses discretely coded numbers or symbols (typically in binary, although other codings like decimal and trinary have been used in certain machines). Changes in value are sudden jumps by at least the smallest representable value. Digital computers can incorporate error detecting and/or correcting circuits.
- Analog computer uses continuously varying signals. Changes in value are smooth and continuous. Analog computers drift with temperature, voltage, component aging, etc. and are very sensitive to noise; any of which can cause undetectable errors.
How did the microscope change human understanding of life?
The microscope brought huge changes to the present world. Without its invention, we wouldn't have developed the remedies for so many diseases. Nor would have we known about the microbial world and its advantages to us.
What developments made personal computing feasible?
The technology itself, silicon chips and so forth, and the ability to mass produce and make the technology affordable.
What is a early example of an analog computer?
The earliest example of an analogue computer - is the 'Difference Engine' - invented by English-man Charles Babbage. Check out Wikipedia for either the equipment or the person for more detailed information.
Two uses of computers in banking?
Most of the banks use tailored software (software programmed to do a specific task)as tailored software are faster and easier to handle in comparison to packaged softwares (MS Offices) the most common use of computer in bank are
- record of financial transactions through out all the branches of bank(for example when you use ATM (automatic teller machine) the transaction you made is first recorded in the machine very itself and then a backup of the transaction is send to the main PC linked to the machine so that if any problem occurs with the machine the balance amount and transactions are recorded
- backup of transactions
- security
- ease of access to cash (credit card, debit card)
- Internet banking
Answer:
Although some unreliable sources list Charles Babbage's full name as Charles Henry Babbage, historians consistently refer to him simply as Charles Babbage, with no middle name, and that is how his name is published in both his official wedding announcement and his obituary.
(Major General) Henry (Prevost) Babbage was the youngest of Charles Babbage's sons who lived to maturity.
Answer:
According to Wikipedia, as well as many other sources, it appears that Charles Babbage is his full name.

Where was the first computer mouse was made?
Well the first mouse was invented by Tom Cranston, Fred Longstaff and Kenyon Taylor, but the design was not patented.
Douglas Engelbart of the Stanford Research Institute invented the wheel-based mouse in 1963. The first ball-based mouse was invented by Bill English at Xerox PARC in 1972.

What invention led to computers becoming smaller and lighter?
Ever since the first computer, advances in technology made it possible to maker smaller and smaller computers. The 50's reduced the size of computers drasticly with the invention of the transistor, which replaced the old glass vaccum valves.
Jack Kirby, development engineer for Texas instruments is credited with the first microchip, the critical technology for microcomputers, The first one was made in 1958.
