Operating System (OS) Interview Questions And Answers - Part VI.



26. Define The Essential Properties Of Distributed Operating System?

Essential properties of Distributed Operating System:
  • Divides computation up among several computers.
  • The computers do not share memory or a clock; they communicate with each other over communication lines (e.g., high-speed bus, telephone line).


27. What Do You Mean By Distributed System? Why Are Distributed Systems Desirable?

An operating system that manages a group of independent computers and makes them appear to be a single computer is known as a distributed operating system. The development of networked computers that could be linked and made to communicate with each other, gave rise to distributed computing. Distributed computations are carried out on more than one machine. When computers in a group work in cooperation, they make a distributed system.

Distributed System is desirable because of following reasons:

  • Any complex jobs can be divided and executed in parallel so that the result is generated more quickly.
  • CPU and clock time sharing happens here which is very important when it comes to parallel processing.
  • System utilization is improved.
  • System idle time is reduced.
  • Job scheduling and job partitioning happens here which increases the efficiency.


28. What Are The Advantages Of Distributed Operating System?

Advantages of distributed OS are:
  • Resource Sharing
  • Higher reliability
  • Better price performance ratio
  • Shorter response time and better throughput.
  • Incremental growth.
