Thread

1. With respect to computer programming, a thread is a portion of code that may be executed independently of the main program. 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 will either terminate or suspend them after a task is completed, or the program is closed.

2. When referring to a computer forum, a thread 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 are a single thread. Below is an illustration to help give you a better idea of how a thread looks.
