Advantages of Computer Increases speed of computing and processing information

in any other way. Computers can store large volumes of information without

occupying too much space. Computer processing eliminates the human errors of

computing and information This reduces the work load of capturing same information

multiple times for different purposes. The work of entering and editing information is made mush

more easy and simple by software that offer many powerful user friendly features for performing these tasks.

Computer now offer sophisticated and powerful software for representing information in rich formats with visual and video facilities.

Computers combined with communication technology offer very fast speed and rich communication facility at low cost.

Computers, with all these features are now used for automating all kinds of equipments and processes.

Disadvantage of ComputersThese equipments are costly as compared to manual processing equipments like pen and pencil. Also technological complexity of these equipment makes it more difficult to learn and maintain these equipments.

Use of computers require additional infrastructure, such as power supply and software back up. This increases the chances of problems due to failure of infrastructure.

Failures of computer system can be more serious and difficult to correct. For example, one scratch on a hard disk can make the complete data on the disk inaccessible.

Computers generally reduces the errors of processing. However if there is an error in input data, it can result in major blunders in the processing which the computer system is unable to detect. In manual systems the chances of such blunders passing undetected and corrected is much less.
