# Process Management Structures

## Core Concepts

- Process:
  - Wikipedia: Process (computing)
  - An instance of a program in execution.
- Process Management:
  - GeeksforGeeks: Process Management in Operating System
  - The tasks performed by an operating system to manage processes.

## Key Data Structures

- Process Control Block (PCB):
  - Wikipedia: Process control block
  - A data structure that stores information about a process, such as its process ID, state, program counter, register values, memory allocation details, and more.
- Process Table:
  - Techopedia: Process Table
  - A table maintained by the operating system that contains entries (usually PCBs) for each active process.

## Process States

- Process State:
  - Wikipedia: Process state
  - Represents the current activity of a process, such as running, ready, blocked (waiting), etc.
- Process State Diagram:
  - GeeksforGeeks: Process States in Operating System
  - Illustrates the possible states of a process and transitions between them.

## Process Scheduling

- Process Scheduling:
  - Tutorialspoint: CPU Scheduling
  - The mechanism by which the operating system determines which process gets access to the CPU and for how long.
- Scheduling Algorithms:
  - GeeksforGeeks: CPU Scheduling Algorithms
  - Various algorithms like First-Come, First-Served (FCFS), Shortest Job First (SJF), Priority Scheduling, Round Robin, etc., used to determine the execution order of processes.

## Inter-process Communication (IPC)

- Inter-process Communication:
  - Wikipedia: Inter-process communication
  - Mechanisms that allow processes to communicate and synchronize with each other. Examples include:
    - Pipes: Wikipedia: Pipeline (Unix)
    - Message Queues: Wikipedia: Message queue
    - Shared Memory: Wikipedia: Shared memory
    - Sockets: Wikipedia: Network socket

## Threads and Concurrency

- Thread (computing):
  - Wikipedia: Thread (computing)
  - A lightweight process that shares resources with other threads within the same process.
- Concurrency (computer science):
  - Wikipedia: Concurrency (computer science)
  - Dealing with multiple tasks seemingly at the same time.
- Thread Synchronization:
  - Tutorialspoint: Thread Synchronization
  - Mechanisms (like mutexes, semaphores, etc.) to prevent race conditions and ensure data consistency when multiple threads access shared resources.

## Additional Resources

- Books:
  - Operating System Concepts by Silberschatz, Galvin, and Gagne (ISBN: 978-1292400451)
  - Modern Operating Systems by Andrew S. Tanenbaum (ISBN: 978-0133591620)
