The nodes in the distributed systems can be arranged in the form of client/server systems or peer to peer systems. 3.

A distributed system is a system that prevents you from doing any work when a computer you have never heard about, fails. The terms "concurrent computing", "parallel computing", and "distributed computing" have much overlap, and no clear distinction exists between them.The same system may be characterized both as "parallel" and "distributed"; the processors in a typical distributed system run concurrently in parallel.
