NOTE

SOFTWARE

Software is a set of instructions usually called a program, which controls the operation of a computer or used to accomplish a specific task.

 

Types of software

Software can be broadly divided into two, namely:

  1. System software:This software helps direct and control the running of computer’s hardware and other connected devices. It helps to manage computer resources such as memory and processor. Examples include Operating system, Translators and utility software.

 

Types of System software

  1. Operating system:Operating system is a suite/set (collection) of programs/software that controls the execution of application programs and coordinates/manages the hardware components. It can also be defined as a set of programs that controls and manages computer resources/components and provides other useful services. The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner.
  2. Translators: Translators are programs that convert programs written in languages other than the machine language to machine language. Examples are Assembler, Interpreter and compiler.
  3. Utility Software:Utility software is system software designed to help analyze, configure, optimize or maintain the operation of a computer, its devices, or its software. Examples include disk utilities like defragmenters, compressors and cleaner. There are also other operating system utilities such as antivirus programs, registry cleaners, Screen saver, file viewer (windows explorer), editors and system restoration programs. Utility softwares are built into the computer operating system, however may be installed separately.
