  • Operating system software -An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system.
  • Functions of operating system – The basic functions of an operating system are: Booting the computer. Performs basic computer tasks eg managing the various peripheral devices eg mouse, keyboard. Provides a user interface, e.g. command line, graphical user interface (GUI).
  • Spreadsheet software – A software interface consisting of an interactive grid made up of cells in which data or formulas are entered for analysis or presentation
  • Word processors – a program or machine for storing, manipulating, and formatting text entered from a keyboard and providing a printout.
  • Compiler – A compiler is a computer program (or a set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language), with the latter often having a binary form known as object code.
  • Interpreter – a program that can analysis and execute a program line by line.
  • Database management system – software that handles the storage, retrieval, and updating of data in a computer system.
  • Antivirus Software – Anti-virus software is a program or set of programs that are designed to prevent, search for, detect, and remove software viruses, and other malicious software like worms, trozans, adware, and more.
  • Boot – The boot process is the name for the various steps the computer takes after you turn it on, all the way until the operating system is loaded.
  • Cold Boot – The start-up of a computer from a powered-down, or off, state. Also called a hard boot.
  • Warm Boot – restarting a computer via the operating system.
