A computer is a machine that manipulates data according to a set of instructions, known as a program. The program is stored in the computer’s memory, and is executed by the computer’s central processing unit (CPU).
The CPU is the heart of the computer. It interprets and executes the program instructions, and controls the other parts of the computer.
The computer’s main memory is where the program is stored while it is being executed. The memory is made up of a large number of small, fast storage cells, called registers.
The computer’s secondary storage is where the program is stored when it is not being executed. This includes the computer’s hard drive, floppy disk, and CD-ROM drive.
The computer’s input devices are used to enter data into the computer. These include the keyboard, mouse, and scanner.
The computer’s output devices are used to display the results of the program. These include the monitor, printer, and speakers.
