Question-4: Can you explain, in layman what is a distributed system?

Answer: In Layman term if we want to create a distributed system, one of the major underline purposes is that even some part of n/w is down. Still system should work. Let’s take an example in your bi-cycle wheel, there are many spokes and all are connected with axle. Even one or few spokes is broken your wheel still works. Hence, there is not a single point of failure.

Question-5: What is distributed computing?

Answer: Distributed computing means a single computer is not responsible for entire computing rather computation is shared across more than one computer. Sometime that is referred as cluster as well. Even in this case if one of the computers in entire cluster fails to process or do computation then another computer from cluster would take the responsibility and completes the failed computation. Communication among the nodes are done by some messaging solution, which could follow different protocols. And goal here is to distribute the heavy computing across the nodes in cluster and collectively complete that complex or big computation like Big Data processing using either Hadoop or Spark.
