What is an Operating System? The Operating System (OS) is a program that controls the computer. A program is a sequence of instructions that guides the computer through the performance of specific task or sequence of tasks. The individual lines of instruction are referred to as code. The term software refers to any program that makes a computer run including operating systems and application programs. Note: Software developers write source code for their programs in a humanreadable format. In order to prepare a program to be installed and used on a computer, the source code is converted into and executable format through a process called compiling. Compiling changes source code into machine code.

What is an Operating System? Application programs use the Operating System to control the hardware functions of the computer. The Operating System Manages hardware devices Controls communication among hardware devices Controls commination between application programs and hardware devices Manages the files stored on the computer
