Application and System Software in detail
System software manages and runs the computer, including the operating system, device drivers and utility programs such as antivirus, backup and disk defragmenters. Application software helps users do tasks, such as word processors, web browsers, spreadsheets, games and photo editors.
Applications run on top of the operating system, which provides common services. Software may be proprietary (paid, with closed source code) or open source (free to view and modify, such as Linux and Firefox). Choosing software means considering cost, features, compatibility and support, and licences define how it can be used.
