We all know operating systems are designed to help us in
normal tasks which done by a compute such as Managing files, Loading programs,
Printing documents etc.
But developers are creating new programs to enhance or
extend the operating system’s capabilities. Those are calls utility software.
Simply utility programs provide new features which are not supported by an
operating system.
Now there are thousands of different utility software and we
can find them on internet for free or with little price.
Although we cannot take a definite list of utility software
categories some common types are,
- Disk and file management programs
- Internet security
- Op customization tools
Antivirus utilities
A virus is a parasitic, scramble files or replicate itself
until the host disk is full. Viruses can be transmitted in numerous ways such
as while transforming files from one to another, downloading files over the
internet or reusing old diskettes etc. So we use antivirus utility software
helps to detect viruses. They can examine content of a disk or RAM for hidden
viruses and files that can act as host for virus code. Effective antivirus
utilities not only detect or delete viruses but also support to recover data
that has been lost because of viruses.
Backup utilities
Backup utilities help us to copy large amount of files from
our hard disk to another storage media such as external hard disk or cd-R disc.
Newly operating systems have this backup utility feature as a built-in package.
But high-featured backup utility programs can be found from other sources also.
Backup utilities also help to organize the files, update backups and restore
backups to disk in case of data loss.
Screen Savers
Screen savers are also popular utilities. It appears
automatically when a keyboard or pointing device has not been used for a specified
period of time.
Firewalls
A firewall may be software utility or hardware device that
act as a filter while data entering or leaving to a computer.it works by
blocking or restricting network ports. Firewall needs highly trained people to
manage them and they may be high in price.
