Explanation: Process Control Block (PCB) contains information related to a process such as Process State, Program Counter, CPU Register, etc. Process Control Block is also known as Task Control Block. Bootstrap program is a program which runs initially when the system or computer is booted or rebooted.

Data structures in the user task control block can be directly read and written by the corresponding task (and depending on the memory protection scheme implemented in the system, by other tasks as well) without using a system call. The user task control block may contain task information that may be accessed by the task.
