Thread

A thread is a particular flow of operations in a computer. Programs can be "multi-threaded", where certain parts of the programs will compete for system resources. Threads are useful for servers, where each client connecting to a server will "spawn" a new thread for its own operations. A program can also run multiple operations concurrently, also known as forking a process. With single-core processors, multi-threading does not usually provide much of an advantage, but with multiple cores, a computer can run the threads concurrently and do multiple programs' work at once.
