Application software covers a large and diverse group of programs specially developed for end users. There are two general groups of application software you can buy: systems software and application software. System software is a group of low-level programs made to interact with your computer on a basic level. These programs are intended to take care of operating systems, compilers and utilities, all made to manage computer resources. The second group, application software, is also known as end-user programs. This group includes various types of word processors, database programs, spreadsheets and more. You can imagine these programs sitting on the top of systems software, since it’s unable to operate without system utilities and programs.
