Single Thread vs Multi Thread

Single Thread:

• In this type of programming only one thread runs at a time.
• The single-threaded model uses a polled process event loop.
• CPU time is wasted. Idle time is more.
• It results in less efficient programs.
• When a thread is paused, the system waits until that thread is resumed.

Multi Thread:

• In this type of programming, multiple threads run concurrently.
• The multi-threaded model does not use a polled event loop.
• CPU time is never wasted. Idle time is minimal.
• It results in more efficient programs.
• When one thread is paused for some reason, other threads run normally.
