multitasking :
1. Multiple tasks, also known as processes, share common
processing resources.
2. You can simultaneously run multiple applications.
3. Heavyweight process
4. Every process have different address space so context
switch or intercommunication between processes is much
expensive.

Multithreading :
1. Subdivide specific operations within a single application
into individual threads.
2. Each of the threads can run in parallel. OS divides
processing time not only among different applications, but
also among each thread within an application.
3. Light weight process
4. Threads for the same application share same address space
so context switch or intercommunication between threads is
less expensive.
