THREADS

A thread is a flow of execution through the process code, with its own program counter that keeps track of which instruction to execute next, system registers which hold its current working variables, and a stack which contains the execution history.

Advantages of Thread

• Threads minimize the context switching time.

• Use of threads provides concurrency within a process.

• Efficient communication.

• It is more economical to create and context switch threads.

• Threads allow utilization of multiprocessor architectures to a greater scale and efficiency.

Types of Thread

Threads are implemented in following two ways −

• User Level Threads − User managed threads.

• Kernel Level Threads − Operating System managed threads acting on kernel, an operating system core.
