A thread may refer to any of the following:

Illustration of CPU threads.

1. With computer programming, a thread is a small set of instructions designed to be scheduled and executed by the CPU independently of the parent process. For example, a program may have an open thread waiting for a specific event to occur or running a separate job, allowing the main program to perform other tasks. A program is capable of having multiple threads open at once and terminates or suspends them after the task is completed or the program is closed.

A multithreading CPU is capable of executing multiple threads concurrently.

Hyper-Threading, an Intel technology, divides a physical core of a CPU into two logical cores, executing an additional, concurrent set of instructions to increase performance.

2. With a computer forum, a thread or threaded discussion consists of an original message or post and each of its corresponding responses. For example, in a newsgroup or message board, a user may post a question relating to computers. Each of the replies relating to the original message is a single thread. Below is an illustration to help give you a better idea of how a thread looks.
