Processes own file handles, sockets, device handles, windows, and a process control block.
2.
The operating system holds most of this information about active processes in data structures called process control blocks.
3.
An SRB is a highly optimized instance of a Process control block in MVS / 370 and successor systems.
4.
A TCB is a general-purpose instance of a Process control block in OS / 360 and successor systems.

An SRB is a highly-optimized instance of a Process control block in these MVS / 370 and successor systems.
6.
A TCB is a general-purpose instance of a Process control block in these OS / 360 and successor systems.
7.
An SRB is similar to a Process Control Block ( PCB ), in that it identifies a unit of work to the system.
8.
Because of the complexities of the OS / 360 and successors control program dispatcher, a TCB does not strictly perform all the functions of a Process control block, although it performs most of these.
9.
Rather, a TCB provides an anchor for a linked list of other, related request control blocks ( RBs ), the composite of which ( i . e ., the TCB plus the top-linked RB ) performs the function of a Process control block.
10.
The kernel AST delivery code, for its part, would check the first flag before trying to deliver a user-mode AST; if it was set, then it would directly set the ASTs-disabled bit in the process control block ( the same bit that would be set by an explicit $ SETAST call from user mode ), and also set the second flag, before returning and leaving the AST undelivered.
