Multiple threads can exist within one process, executing concurrently and sharing resources such as memorywhile different processes do not share these resources. In particular, the threads of a process share its executable code and the values of its dynamically allocated variables and non- thread-local global variables at any given time. Systems with a single processor generally implement multithreading by time slicing : the central processing unit CPU switches between different software threads.

Thread (computing)

This context switching generally happens very often and rapidly enough that users perceive the threads or tasks as running in parallel. On a multiprocessor or multi-core system, multiple threads can execute in parallelwith every processor or core executing a separate thread simultaneously; on a processor or core with hardware threadsseparate software threads can also be executed concurrently by separate hardware threads.

Saltzer credits Victor A. Vyssotsky with the term "thread". Some threading implementations are called kernel threadswhereas light-weight processes LWP are a specific type of kernel thread that share the same state and information. Furthermore, programs can have user-space threads when threading with timers, signals, or other methods to interrupt their own execution, performing a sort of ad hoc time-slicing.

Threads differ from traditional multitasking operating-system processes in several ways:. In computer programmingsingle-threading is the processing of one command at a time. In the formal analysis of the variables' semantics and process state, the term single threading can be used differently to mean "backtracking within a single thread", which is common in the functional programming community.

Multithreading is mainly found in multitasking operating systems. Multithreading is a widespread programming and execution model that allows multiple threads to exist within the context of one process.

These threads share the process's resources, but are able to execute independently. The threaded programming model provides developers with a useful abstraction of concurrent execution. Multithreading can also be applied to one process to enable parallel execution on a multiprocessing system.

Operating systems schedule threads either preemptively or cooperatively. On multi-user operating systemspreemptive multithreading is the more widely used approach for its finer grained control over execution time via context switching. However, preemptive scheduling may context switch threads at moments unanticipated by programmers therefore causing lock convoypriority inversionor other side-effects. In contrast, cooperative multithreading relies on threads to relinquish control of execution thus ensuring that threads run to completion.

This can create problems if a cooperatively multitasked thread blocks by waiting on a resource or if it starves other threads by not yielding control of execution during intensive computation. Until the early s, most desktop computers had only one single-core CPU, with no support for hardware threadsalthough threads were still used on such computers because switching between threads was generally still quicker than full-process context switches.

Scheduling can be done at the kernel level or user level, and multitasking can be done preemptively or cooperatively.

This yields a variety of related concepts. At the kernel level, a process contains one or more kernel threadswhich share the process's resources, such as memory and file handles — a process is a unit of resources, while a thread is a unit of scheduling and execution. Kernel scheduling is typically uniformly done preemptively or, less commonly, cooperatively. At the user level a process such as a runtime system can itself schedule multiple threads of execution.

If these do not share data, as in Erlang, they are usually analogously called processes, [7] while if they share data they are usually called user threadsparticularly if preemptively scheduled.

Cooperatively scheduled user threads are known as fibers ; different processes may schedule user threads differently. User threads may be executed by kernel threads in various ways one-to-one, many-to-one, many-to-many.

The term " light-weight process " variously refers to user threads or to kernel mechanisms for scheduling user threads onto kernel threads. A process is a "heavyweight" unit of kernel scheduling, as creating, destroying, and switching processes is relatively expensive. Processes own resources allocated by the operating system.Add thread to one of your lists below, or create a new one. Definitions Clear explanations of natural written and spoken English.

In most modern operating systems, a thread exists within a process - that is, a single process may contain multiple threads. You can imagine multitasking as something that allows processes to run concurrently, while multithreading allows sub-processes to run concurrently.

define thread

When multiple threads are running concurrently, this is known as multithreading, which is similar to multitasking. Basically, an operating system with multitasking capabilities allows programs or processes to run seemingly at the same time. On the other hand, a single program with multithreading capabilities allows individual sub-processes or threads to run seemingly at the same time.

One example of multithreading is downloading a video while playing it at the same time. Multithreading is also used extensively in computer-generated animation. Among the widely-used programming languages that allow developers to work on threads in their program source code are Java, Python and.

For example, a program may have an open thread waiting for a specific event to occur or running a separate joballowing 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-Threadingan Intel technology, divides a physical core of a CPU into two logical cores, executing an additional, concurrent set of instructions to increase performance.
