Multithreading is a CPU (central processing unit) feature that allows two or more instruction threads to execute independently while sharing the same process A thread is a self-contained sequence of instructions that can execute in parallel with other threads that are part of the same root process.

A process with two threads of execution, running on a single processor In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution concurrently, supported by the operating system.

The process of executing multiple tasks (also called threads) simultaneously is called multithreading. The primary purpose of multithreading is to provide simultaneous execution of two or more parts of a program to make maximum use of CPU time. A multithreaded program contains two or more parts that can run concurrently.

A feature within a CPU that allows two or more instruction streams (threads) to execute concurrently. Each stream is a "subprocess" that is managed by the CPU and operating system.
