Distributed Computing System

- Kishor M Sonawane



Distributed Computing System:

    first following things remember
    1. single core processor use then speed less if we improve speed of single core then the Core Heading Problems Come.
2. avoid this multi-core come and again come SUPER Computer Concept to perform Complex Operation, large data processing etc.
but in Super Computer System some Problems Such As Computer Size-it required big room, and super computer have its own instruction set so programmer had to study Set Of  instruction set.

 Avoid This Problems Distributed Computing System Comes. the name say its fact the many computer(minicomputer or workstation) work together and thy are physically  located at any location.

in this system many computer use so data and program replicated means many copies of program as well as data. means programmer challenges to manege this data consistency, security, maintenance etc.
Distributed Computing System is MIMD means Multiple Instruction Multiple Data
how ?? many Computer same time execute instruction and many computer data also available..


two types of Architecture:
 1. loosely coupled and
 2. tightly coupled system
