Hi Pankaj,

Threads are a specific example of concurrency.

"Concurrency occurs when two or more execution flows are able to run simultaneously."

Threads are a way for programs to do several different tasks at the same time -- that is, concurrently. (They're not the only mechanism; another is to use several "processes").

The following is a good page to read to understand situations where you could apply multithreading:
