Chapter 1: Large Contiguous Process Control Block Structure

These flashcards cover key concepts related to the process control block and thread management in operating systems.

Process Control Block (PCB)

A data structure in the operating system that contains information about a process.

Kernel Level Threads

Threads that are managed by the operating system's kernel.

Context Switching

The process of storing the state of a thread so that it can be resumed later.

User Level Threads

Threads that are managed by a user-level threading library rather than the kernel.

Hard Process State

Information in the process control block that is relevant for all user level threads in a process.

Lightweight Process State

Information in the process control block that is specific to a subset of user level threads associated with a particular kernel level thread.

Virtual Address Mappings

Mappings that translate virtual addresses to physical addresses in memory.

Threading Library

A library that provides methods for managing and scheduling threads.
