    • It is an interconnected collection of autonomous computers.
    • Two computers are said to interconnected if they are able to exchange information.
    • The connection need not be via copper wire.fiber optics,microwaves and communication satellites can also be used
       
    Distributed Systems
    • The existence of autonomous computers is transparent(i.e .,not visible) to the user..
    • The user can type a command to run a program,and it runs.
    • The operating system selects the best processor,finds and transports all input files to that processor,and puts the result in the appropriate place..
    • The user of a distributed system is not aware that there are multiple processors , it looks like a virtual uniprocessor.
    • The software is built on top of a network.
