Advantages of computers: Increases speed of computing and processing information in any other way. People can use sophisticated statistical and mathematical tools for decision making and further purposes without learning in details the algorithms used for computing. This way people can use much more sophisticated analytical tools that would have been possible with only manual information processing. Computers can store large volumes of information without occupying too much space, as is in the case of information stored in form of books and paper documents.

Computer processing eliminates the human errors of computing and information processing. Information once entered in computer system can be easily accessed by the same person or other persons at different times for different persons. This reduces the work load of capturing same information multiple times for different purposes. It also makes it possible for different person to work with same information, avoiding the possibility of different persons using different versions of the same information.

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. In comparison, manual system faults have comparatively limited impact. One page torn from a cabinet full of documents has no impact on other documents. 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.
