Open Source Software
Public Domain Software
serves as the interface between the user, the application software, and the computer's hardware. To use application software, such as a word processing program, your computer must be running system software — specifically, an operating system. Three popular personal computer operating systems are Windows, Mac OS, and Linux.
Each time you start a computer, the operat- ing system is loaded (copied) from the computer's hard disk into memory. Once the operating sys- tem is loaded, it coordinates all the activities of the computer. This includes starting application software and transferring data among input and output devices and memory.
