Centralized Data Processing (CDP) uses Centralised computers, processing, data, control, support. The advantages are Economy for equipment and personnel, Lack of duplication, Ease in enforcing standards, security. In Distributed Data Processing (DDP)Computers are dispersed throughout organisation. Which allows greater flexibility in structure, More redundancy and More autonomy.
Hi,
Centralized data processing is a Computer data processing architecture where data processing support is provided by one or a cluster of computers, generally a large. dedicated computers, located in a central data processing facility. In a centralized architecture, each person is provided with a local terminal that is connected by a communications facility to the central data processing facility.
A fully centralized data processing has following features:
1. Centralized computers
2. Centralized processing
3. Centralized Data
4. Centralized Control
5. Centralized Staff Support
A Distributed data processing facility is one in which computers, usually smaller computers, are dispersed throughout the organization. The objective of such disperse is to process information in a way that is most effective based on operational.
Therefore, DDP (Distributed Data Processing) features:
1. A collection of terminals link together by some kind of communication link and has no main central computer or not fully (minimal) depend on central computer.
2. Processing of information is happening on each terminal and send results to a main server for store and retrieval purposes.
3. Data may duplicate as data may store in locally or in remote server.
4. Local computer operator can control the machine in his premises.
5. Separate staff will maintain central computer (if there any) where other terminals may control by one or few other members.
Hope this will help you!

∙ 11y agoIn a centralised system, everything comes back to a Central (Single) Server. Replicas (Images) may be created from the master system. (Best example: A regular Client Server network in offices)
In a decentralized system, there is no one Central server. There would be many servers but they would be programmed to synchronize synchronize regularly. (Example: Ideally a network of a company that is extremely large would be decentralized. Not sure of any particular example. internet also qualifies as a decentralized network although not a pure decentralized network)

What is the difference between centralized and decentralized billing?
Centralized billing is performed by a group or department in a central location to an organization. Decentralized billing is where various individuals have the responsibility to bill for their product or services from field locations. There are advantages and disadvantages of both types of billing methods. Centralized billing offers control of the workflow, easier to manage from a corporate perspective and easier for metric purposes (depending on your industry). Decentralized billing is often best used in situations where billing is complex and technical in nature. Billing information is closer to the work being performed and thus Q&A is faster (and hopefully more accurate) in a decentralized environment.
Difference between centralisation and decentralisation in management?
Centralized management means that there is one main manager who has a majority control. Decentralized management means that there are many managers that hold the same level of authority.
What is the difference between centralized and decentralized maintenance?
Centralized maintenance means that those charged with maintaining equipment, buildings, grounds and many more. it have a common supervisor so that the company does not waste time or money on duplication or working at cross purposes. Centralized organizations are those that workers are not involved in devision making while decentralized organization are those which involve their workers in decision making. Decentralized maintenance function can produce quicker respond time and allow workers to become more familir with the problems of a particular section of the plant. For centralized maintenance, in the creation of a number of small unit tense to reduce the flexibility of the maintenance system as a whole.
