Who is the owner of the Apple Company?
The owner of the Apple Company is the shareholders, as a group.
The CEO was Steve Jobs, but he just died on 5 October 2011 now Tim Cook is the CEO.
What are computers used for most?
Computers have a wide variety of uses by each person.
The most common use is communication(email, chat, AIM, etc.) and research and news(internet). Other uses include word processing, creating spreadsheets, inventory recording and maintenance, creating visual aides for meetings/presentations.

It depends on the size of the classroom!
ENIAC ( Electronic Numerical Integrator And Computer) was the first general-purpose computer, and, by today's standards, was quite large!
It weighed 27 tons. The floor area was about 8.5 ft by 80 ft, i.e. 680 sq. ft., and it occupied about 225 cubic yards of space.
The recommended size of a classroom in the United States is about 900 square feet, so it probably wouldn't be a problem fitting ENIAC, at only 680 sq. ft, into the room, and you'd have a small area of about 15 ft x 15 ft to spare!
PROJECT: Measure your classroom. Would ENIAC fill it?

How much did the Analytical Engine cost when it was made?
The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, a design for a mechanical computer. The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. In other words, the logical structure of the Analytical Engine was essentially the same as that which has dominated computer design in the electronic era.
Babbage was never able to complete construction of any of his machines due to conflicts with his chief engineer and inadequate funding.It was not until the 1940s that the first general-purpose computers were actually built, more than a century after Babbage had proposed the pioneering Analytical Engine in 1837.

What is the old standard browser-NCSA?
NCSA, also known as Mosaic, is the web browser that is known for popularizing the Internet.
After the abacus what computer was invented?
Abacus --> Napier's Bones --> Pascaline --> Leibnitz's Calculator --> Jacquard's Loom --> Babbage's Difference Engine --> Babbage's Analytical Engine --> Hollerith's Machine --> Mark I
First, the easy part- Binary is used because digital computers use rely on the extant state of transistors to complete operations. Transistors have only two states: off (0) and on (1).
Binary-Decimal conversion is fairly simple also. The key is that each order of magnitude in a binary number represents a power of two.
So starting at the least significant bit (to the far right) it is 2^0:
1=1
0=0
Next is 2^1:
1=2
0=0
2^2:
1=4
0=0
And so on. So if one had 10101101 as their integer:
2^0 = 1 = 1
2^1 = 0 = 0
2^2 = 1 = 4
2^3 = 1 = 8
2^4 = 0 = 0
2^5 = 1 = 32
2^6 = 0 = 0
2^7 = 1 = 128
The integer is the sum of each bit's value, in this case 173.
What are mini-Pci slots used for?
Its not mini PCI, its just PCI, they just look mini compared to a PCI-E.
It depends on which PCI slot it is, there are tons of different cards that are for PCI.
Sound, wireless, modem.
Look at the spec's for the motherboard to see what slots you have, then you know what cards you can use.
He has been internationally recognized for his outstanding contributions to computer science education. The list of projects produced, contributed to, or maintained by the nonprofit Viewpoints Research Institute (VRI) that he started in 2001 is quite impressive.
