+# Process Management Structures
+
+## Core Concepts
+
+- **Process:**
+    - [Wikipedia: Process (computing)](https://en.wikipedia.org/wiki/Process_(computing))
+    - An instance of a program in execution.
+- **Process Management:**
+    - [GeeksforGeeks: Process Management in Operating System](https://www.geeksforgeeks.org/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](https://en.wikipedia.org/wiki/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](https://www.techopedia.com/definition/1066/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](https://en.wikipedia.org/wiki/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](https://www.geeksforgeeks.org/process-states-in-operating-system/) 
+    - Illustrates the possible states of a process and transitions between them.
+
+## Process Scheduling
+
+- **Process Scheduling:**
+    - [Tutorialspoint: CPU Scheduling](https://www.tutorialspoint.com/operating_system/os_process_scheduling.htm)
+    - 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](https://www.geeksforgeeks.org/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](https://en.wikipedia.org/wiki/Inter-process_communication)
+    - Mechanisms that allow processes to communicate and synchronize with each other. Examples include:
+        - **Pipes:** [Wikipedia: Pipeline (Unix)](https://en.wikipedia.org/wiki/Pipeline_(Unix))
+        - **Message Queues:** [Wikipedia: Message queue](https://en.wikipedia.org/wiki/Message_queue)
+        - **Shared Memory:** [Wikipedia: Shared memory](https://en.wikipedia.org/wiki/Shared_memory)
+        - **Sockets:** [Wikipedia: Network socket](https://en.wikipedia.org/wiki/Network_socket)
+
+## Threads and Concurrency
+
+- **Thread (computing):**
+    - [Wikipedia: Thread (computing)](https://en.wikipedia.org/wiki/Thread_(computing))
+    - A lightweight process that shares resources with other threads within the same process.
+- **Concurrency (computer science):**
+    - [Wikipedia: Concurrency (computer science)](https://en.wikipedia.org/wiki/Concurrency_(computer_science))
+    - Dealing with multiple tasks seemingly at the same time.
+- **Thread Synchronization:**
+    - [Tutorialspoint: Thread Synchronization](https://www.tutorialspoint.com/operating-system/os_thread_synchronization.htm)
+    - Mechanisms (like mutexes, semaphores, etc.) to prevent race conditions and ensure data consistency when multiple threads access shared resources.
+
