1. How a computer works

2. The word computer refers to an object that can accept some input and produce some output. In fact, the human brain itself is a sophisticated computer, and scientists are learning more about how it works with each passing year. Our most common use of the word computer, though, is to describe an electronic device containing a microprocessor. A microprocessor is just like the human brain it works out calculations like when you are typing it will be a calculation

3. The components inside a computer The system unit is the core of a computer system. Usually it's a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. Another component is random access memory (RAM), which temporarily stores information that the CPU uses while the computer is on. The information stored in RAM is erased when the computer is turned off.

4. In most daily used computers there is a disk with a rotating arm that if you turn the computer upside down you will permanently and you will not be able to fix it and on that disk is everything you have done on that computer and no matter if you turn it off or delete your history it will still be there and that’s how people get to find out things that they should not

5. facts  In all modern day cars is a computer so if they stopped making computers there will be a shortage of cars  Things have got that good that in everything you use everyday has a computer in it to tell it what to do and when to do it like a microwave if you press start you don’t want it to start 10mins later that’s why there is a computer I everything

6. 1940 The Complex Number Calculator (CNC) is completed. In 1939, Bell Telephone Laboratories completed this calculator, designed by researcher George Stibitz. In 1940, Stibitz demonstrated the CNC at an American Mathematical Society conference held at Dartmouth College. The Complex Number Calculator (CNC) is completed.

7. In 1994 In 1994 The Iomega Zip Disk is released. The initial Zip system allowed 100MB to be stored on a cartridge roughly the size of a 3 ½ inch floppy disk. Later versions increased the capacity of a single disk from 100Mbytes to 2GB.

8. In 1993 the microprocessor was relesed In 1993 the microprocessor was relesed
