In computer programming, thread-local storage (TLS) is a memory management method that uses static or global memory local to a thread. The concept allows storage of data that appears to be global in a system with separate threads.

Thread-local storage Variables are localized so that each thread has its own private copy. These variables retain their values across subroutine and other code boundaries and are thread-safe since they are local to each thread, even though the code which accesses them might be executed simultaneously by another thread. Immutable objects
Data storage that is directly attached to a compute device; A network-attached storage device accessed via a local network, rather than a wide area network; Local storage, a JavaScript web storage facility allowing websites to store data on a user's device; Local shared object (or Flash cookie), Adobe Flash data stored on a user's computer
A process with two threads of execution, running on one processor Program vs. Process vs. Thread Scheduling, Preemption, Context Switching. In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [1]
Current Linux also uses GS to point to thread-local storage. Segments can be defined to be either code, data, or system segments. Additional permission bits are present to make segments read only, read/write, execute, etc. In protected mode, code may always modify all segment registers except CS (the code segment selector). This is because the ...
On Microsoft Windows, fibers are created using the ConvertThreadToFiber and CreateFiber calls; a fiber that is currently suspended may be resumed in any thread. Fiber-local storage, analogous to thread-local storage, may be used to create unique copies of variables. [3] Symbian OS used a similar concept to fibers in its Active Scheduler.
The stack is often used to store variables of fixed length local to the currently active functions. Programmers may further choose to explicitly use the stack to store local data of variable length. If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).
