What are the advantages of distributed processing?

Explanation

  • Security/Encapsulation
    • A system designer can limit the kinds of interactions that a given user can have with the entire system.
    • For example, a bank can allow users ′ access to their own accounts through an auto mated teller machine (ATM) without allowing them access to the bank ′ s entire database.
  • Distributed Database
    • No one system needs to provide storage capacity for the entire database.
    • For example, the World Wide Web gives users access to information that may be actually stored and manipulated anywhere on the internet.
  • Faster Problem Solving
    • Multiple computers working on parts of a problem concurrently in a distributed system can solve it faster.
    • For example, network of PCs can break encryption codes presumed to be unbreakable.
  • Security through Redundancy
    • Multiple computers running the same program at the same time can provide security through redundancy.
    • For example, in the space shuttle, three computers run the same program so that if one has a hardware error, the other two can override it.
  • Collaborative Processing
    • Both multiple computers and multiple users may interact on a task.
    • For example, in multi-user network games the actions of each player are visible to and affect all the others.
