Multiple Kernel Level and Process Control

These flashcards cover key terms and concepts related to multiple kernel-level threading and process control, focusing on user and kernel-level threads, process control blocks, and context switching.

User Level Threads

Threads that are managed by a user-level threading library and are an abstraction for processes.

Process Control Block (PCB)

A data structure maintained by the operating system to represent information about a process.

Kernel Level Threads

Threads that are managed by the operating system kernel, providing better performance and management.

CPU Affinity

The tendency of a thread to be computed on the same CPU core to improve performance.

Context Switching

The process of storing the state of a current process or thread and restoring the state of another process or thread.

Address Space

The range of memory addresses that a process can use for its execution.

Multi-threading in Kernel

The capability of the kernel to manage multiple threads for a single process for better performance.

Virtual Address Mapping

A mechanism that maps virtual addresses to physical memory addresses.
