Systems software are programs that manage the resources of the computer system and simplify applications programming. They include software such as the operating system, database management systems, networking software, translators, and software utilities. Application Software.
The software environment is the term commonly used to refer to support an application. A software environment for a particular application could include the operating system, the database system, specific development tools or compiler.
An application is any program, or group of programs, that is designed for the end user. Applications software (also called end-user programs) include such things as database programs, word processors, Web browsers and spreadsheets.
An operating system (OS) is a software program that serves as the interface between other applications and the hardware on a computer or mobile device.
A database is a collection of information organized in such a way that a computer program can quickly select desired pieces of data. You can think of a traditional database as an electronic filing system, organized by fields, records, and files.
A compiler is a program that translates source code into object code to be understood by a specific central processing unit (CPU). The act of translating source code into object code is known as compilation. Compilation is typically used for programs that translate source code from a high-level programming language (such as C++) to a low-level programming language (such as machine code) to create an executable program. Likewise, when a low-level language is converted into a high-level language, the process is called decompilation.
