Advantages and Disadvantages of Using Computer

Advantages of computers Increases speed of calculate and processing study in any other way. People butt use sophisticated statistical and mathematical tools for decision making and nonwithstanding purposes without learning in details the algorithms used for computing. This way people domiciliate use much more than sophisticated analytical tools that would have been thinkable 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 actus reuss of computing and information processing. discipline once entered in computer system can be favorable accessed by the same person or other persons at antithetical times for different persons. This reduces the operate on load of capturing same information fivefold times for different purposes. It also makes it possible for different person to forge with same information, avoiding the possibility of different persons using different versions of the same information.The work of entering and editing information is made mush more easy and simple by softw ar that offer many potent user friendly features for performing these tasks. Computer this instant offer sophisticated and powerful software package for representing information in racy formats with visual and video facilities. Computers combine 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 Computers The cost of computer and associated equipments is falling steadily.Still these equipments are and continue to be much more 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 as comp ared to equipments of manual information processing. drug abuse of computers require additional infrastructure, such as power offer and software back up. This increases the chances of problems due to failure of infrastructure. For example, a computer will not work where there is no electric power supply. Even a laptop with a battery will work without power supply only for a moderate period.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 muc h less.
