**How computers operate**
Computers operate with several parts working all together as one. The hardware is the physical parts of the computer and the software being the programs like the 0's and 1's that instruct the computer what to do. The hardware runs program instructions and controls other hardware its more like the brain of the whole computer. All computers have a ALU to function it performs arithmetic and logic operations on binary integers. (and,or,xor,not) for an example. Then the control unit tells the computer components like the memory and the ALU how to respond to computer instructions. Computers have memory hardware that stores data. The keyboard is important so the user can input the characters to the hardware. Of course the screen is required to display characters and images to the user.
