A computer receives, compares, changes, and manipulates data.
A computer program is a set of instructions that tells a computer what to do. A program is also known as software.
There are three basic steps in handling data; input - entering data and instructions that enable the computer to do a specific job; processing - sorting data and doing calculations; and output - sending the results of processing to a storage or display device.
Software is the set of instructions that tells the computer what to do. Hardware is the physical parts of a computer, including peripherals.
A computer receives your input through the keyboard, disk drive, and other parts that you use lo give it data or instructions. Processing includes sorting, calculating, and other steps involved in following your instructions. The information that results from the processing is called output. The computer displays output on its screen and can print the output or store it on tapes or disks.
The central processing unit, or CPU, is the computer's "brain". It has a control unit and an arithmetic / logic unit. The control unit determines whether
the
arithmetic / logic
unit will add, subtract, or compare the numbers it was given.
A single silicon chip can be the entire CPU of microcomputer. A chip contains thousands of tiny, interconnected electrical circuits.
A computer's ROM is not affected when you turn off the computer. ROM includes built-in instructions that tell the machine what to do when you turn it on and how to perform calculations. RAM is a temporary memory that holds your input while you arc working with it.
