Operating System (OS) An operating system is a collection of
programs that control the application software that users run and provides a link between the hardware and software currently running on the computer.
The operating system is also responsible for the management and control of all resources (memory, hard drives, monitor, etc.) that are shared amongst the different application programs that may be running simultaneously.
Application Software Application software is a program or group of
programs designed for end users. These programs are divided into two classes : o system software o application software
While system software consists of low-level programs that interact with computers at a basic level, application software resides above system software and includes database programs, word processors, spreadsheets, etc.
Application software may be grouped along with system software or published alone.
Utilities Software Utility software is system software
designed to help analyze, configure, optimize or maintain a computer.
A program that performs a very specific task, usually related to managing system resources. Operating systems contain a number of utilities for managing disk drives, printers, and other devices.
Programming Software A programming tool or software
development tool is a program or application that software developers use to create, debug, maintain, or otherwise support other programs and applications.
The term usually refers to relatively simple programs that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object.
