What do they mean by multi threading

An application has the ability to run multiple threads simultaneously.

Answer: computer architecture, multithreading is the ability of a central processing unit to provide multiple threads of execution concurrently, supported by the operating system. This approach differs from multiprocessing.

Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the programming running in the computer.

The Benefits of Multithreaded Programming. Multithreading allows the execution of multiple parts of a program at the same time. These parts are known as threads and are lightweight processes available within the process. So multithreading leads to maximum utilization of the CPU by multitasking.
