- Software, also called computer programs, is a series of instructions that tells the hardware of a PC what to do. Software is not as physically tangible as hardware, but it is just as important to a PC.
- System software controls the operation of the PC and its devices, and provides an interface to the PC for the user. Operating system software controls all activities of the PC. The OS is loaded when ever the PC is turned on. Most operating systems today offer a graphical user interface, instead of the old text based command lines.
- Utility software is usually small applications designed to manage a part of the PC’s hardware or software.
- Application software is what makes a Personal Computer useful. Applications perform specific tasks, like a word processor, web browser, video editor, etc.
- Software usually comes on CD, DVD, floppies, etc., but can also be downloaded from the internet or a network.
