Basics of Computers – Utility Software

 👉What is Utility Software?

  •   Application software that assists OS in carrying out certain specialized tasks is called utility software.
⇉ Some of the most popular utility software.
  1. Antivirus
  2. File management tools
  3. Compression tools
  4. Disk Cleanup
  5. Disk Defragmenter
  6. Backup

1.Antivirus

A virus can be defined as a malicious program that attaches itself to a host program and makes multiple copies of itself, slowing down, corrupting or destroying the system. A software that assists the OS in providing virus free environment to the users is called antivirus. An anti-virus scans the system for any virus and if detected, gets rid of it by deleting or isolating it. It can detect many types of virus like boot virus, Trojan, worm, spyware, etc.

2.File management tools

As you know, file management is an important function of operating systems as all data and instructions are stored in the computer in form of files. Utility software providing regular file management tasks like browse, search, update, preview, etc. are called file management tools. Windows Explorer in Windows OS, Google desktop, Directory Opus, Double Commander, etc. are examples of such tools.

3.Compression tools

Storage space is always at a premium in computer systems. So operating systems are always looking at ways to minimize the amount of storage space taken by files. Compression tools are utilities that assist operating systems in shortening files so that they take less space. After compression files are stored in a different format and cannot be read or edited directly. It needs to be uncompressed before it can be accessed for further use. Some of the popular compression tools are WinRAR, PeaZip, The Unarchiver, etc.

4.Disk Cleanup

Disk cleanup tools assist users in freeing up disk space. The software scans hard disks to find files that are no longer used and frees up space by deleting them.

5.Disk Defragmenter

Disk defragmenter is a disk management utility that increases file access speeds by rearranging fragmented files on contiguous locations. Large files are broken down into fragments and maybe stores in non-contiguous locations if contiguous ones are not available. When such files are accessed by the user, the access speed is slow due to fragmentation. The disk defragmenter utility scans the hard disk and tries to assemble file fragments so that they may be stored in contiguous locations.

6.Backup

Backup utility enables backing up of files, folders, databases or complete disks. Backups are taken so that data may be restored in case of data loss. Backup is a service provided by all operating systems. In stand-alone systems backup may be taken in the same or different drive. In case of networked systems backup may be done on backup servers.

The literal meaning of a computer is a device that can calculate. However, modern computers can do a lot more than calculating. The computer  is an electronic device that receives input, stores or processes the input as per user instructions, and provides output in the desired format. Characteristics of Computer To understand why computers are such an important part of our lives, let us look at some of their characteristics − Speed   − Typically, a computer can carry out 3-4 million instructions per second. Accuracy   − Computers exhibit
