2.14    DECENTRALISED RESULT PROCESSING
In the decentralized data processing, each locality or department is provided with a computer system and does not necessarily have any thing in common. Each centre handles its own data processing needs and generally does not interacts with any other division or centers. It quickly responds to divisional needs and suits a decentralized management scheme. However, it is expensive on account of duplication of facilities and files. Here processing in a department is independent of one another( Osaula, 1978).

2.15    DISTRIBUTED RESULT PROCESSING SYSTEM
Distributed processing is a term defined by the National Computer Center as a system in which there are several autonomous but interacting processors and or data stores at different geographical locations. In other words, distributed processing links several computers together. Distributed processing might involve the combination of a central computer and other usually smaller computer at different locations, linked together by a data communication network. For example, remote micro with a keyboard and VDU can act as network. For example remote micros with a keyboard NS VDU can act as intelligent terminals to a central mainframe. All the results files to be located centrally with the smaller computer. The main features of distributed result processing system; as compared to a centralized DP system is that instead of carrying out all processing from a standalone central computer with a set of central files, a distributed system design, but the key features of distributed processing locations. There is some flexibility in such computer system design but the features of distributed processing are as follows: Computer are distributed or spread over a wide geographical area. The ability for one computer in the system to have access to the information files of other computers in the system i.e. to share files. The ability for computer s within the system to process result jointly or interactively. Distributed result processing is generally associated with either: A number stand alone microcomputer being used to process result in a number of different department in a school; each microcomputer operates in independently of the other (either a wide area network or a local area network) (Anigbogu, 2002).
