[[Category:Encyclopedia]]A '''thread''' is a particular flow of control within a [[process]]. A thread shares the address space with other threads in the same process, but each thread gets its own call stack and set of registers. Switching between threads within a process is a much lighter-weight operation than switching between processes. Threads can by ''native'' (provided by the [[:Category:Operating Systems|operating system]]) or ''green'' (an abstraction provided solely by the language or threading library). [[Erlang]] and [[Forth]] provide their own threading mechanisms, and [[Java]] VMs can often be configured to use either native or green threading.
Programs can be "[[Simple concurrent actions|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.
One of the best known threading abstractions is '''[[POSIX]] threads''' (pthreads), which are widely used on [[UNIX]]-like systems.
