8. 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.

9. Disadvantage of Computers
These 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.
