Main advantages of Multithreading are:

1. Improved performance: We can improve performance of a

job by Multi-threading.

2. Simultaneous access to Multiple Applications: We can

access multiple applications from a process by doing

multithreading

3. Reduced number of Servers required: With Multithreading we need lesser number of servers, since one

process can spawn multiple threads.

4. Simplified Coding: In certain scenarios, it is easier to

code multiple threads than managing it from same thread.
