'''Thread Control Block''' (TCB) is a [[data structure]] in the [[operating system kernel]] containingwhich thecontains [[Thread (computing)|thread]]-specific information needed to manage a particular processit. The TCB is "the manifestation of a thread in an operating system".

An example of information contained within a TCB is:

'''Thread Control Block''' (TCB) is a [[data structure]] in the [[operating system kernel]] containing the information needed to manage a particular process. The TCB is "the manifestation of a thread in an operating system".

* [[Stack pointer]]: Points to thread's stack in the process

* [[Program coutner]]

Thread control block contain thread specific information such as

* State of the thread (running, ready, waiting, start, done)

* Thread's [[Processor register|register]] values

-[[Stack pointer]], PC, thread state (running, …), register values, a pointer to PCB, …

* Pointer to the [[Process control block]] (PCB) of the process thread lives on

The Thread Control Block acts as a library of information about the [[Thread (computing)|Threads]] in a system. Specific information is stored in the Thread control block highlighting important information about each process.
