Lightweight Process Data

Flashcards covering key concepts and vocabulary related to lightweight process data in operating systems.

Kernel Level Data Structures

Data structures in the operating system kernel that maintain information about processes and threads.

Lightweight Process

A data structure that contains information relevant to a subset of a process and user level threads.

User Credentials

Information that establishes a user's identity and permissions, crucial for file access and security.

Signal Handlers

Functions that the operating system calls in response to specific events or signals for a process.

Resource Usage Information

Data maintained to track how resources are utilized by processes and threads.

Kernel Level Thread Structure

Contains essential information about a kernel-level thread, such as execution context.

Swappable Information

Data that can be temporarily moved out of memory during memory pressure, applicable to lightweight process data.

Current Thread

The thread that is currently scheduled to run on a CPU.

CPU Data Structure

Contains information necessary for thread scheduling and processing on a CPU.

Context Switch

The process of storing and restoring the state of a CPU so that multiple processes can share a single CPU resource.

Dispatching a Thread

The process of allocating CPU resources to a thread for execution.

Address Space

The range of memory addresses that a process can use.
