Utility Programs
The utility programs are used to provide end users with a tool box to fine tune hardware components or modify system software functions.
The utility programs for large computer systems are designed for professional system programmers to either modify or repair the system software.
However the utility programs for microcomputers are very often used by end users.
They are use friendly and designed for end users, change the monitor’s background pattern, or install computer hardware.
Some vendors provide utility programs that can enhance the performance of the computer, such virtual memory and virus protection.
Some of the principal utility programs are as follows:
Data recovery
A data recovery utility is used to “undelete” a file or information that has been accidentally deleted. With this function, users are able to undo the last delete operation that has taken place.
Screen saver
A screen saver prevents a monitor’s display screen from being etched by an unchanging image.
Backup
The backup utility allows users to make a backup (duplicate) copy of the information on the hard disk.
Data compression
Data compression removes redundant elements, gaps, and unnecessary data from a computer’s storage space, so less space is required to store or transmit data.
Virus protection
A virus consists of hidden programming instructions that are buried within an application or system program. They can reproduce themselves and cause damage to computer programs.
