Difference Between Multitasking and Multithreading in OS
In this post, we will understand the difference between multitasking and multithreading in an operating system −
Multitasking
In this process, the users are allowed to perform multiple tasks by CPU.
It involves CPU switching between tasks.
The processes share separate memory locations.
It involves multiprocessing.
The CPU is provided to execute many tasks at a time.
The processes don’t share the same resources.
Every process is assigned its own resources.
It is slow in comparison to multithreading.
The process of termination takes more time.
This is how Multi-tasking looks like −
Multithreading
Multiple threads are created from a process.
Due to this, the power of computer is increased.
It involves CPU switching between the threads.
The processes are allocated same memory.
It doesn’t involve multiprocessing.
The CPU is provided so that multiple threads can be executed at a specific time.
Every process shares the same set of resources with each other.
It is fast.
The process of thread termination takes less time.
A multi-threaded process looks like the following −
