In modern computer systems, processes are essential for executing applications and managing system resources efficiently. A process is a running instance of a program, encompassing its executable code, memory, and state information. The operating system (OS) is responsible for process management, ensuring seamless execution, CPU scheduling, and resource allocation.
This lecture on process management explores how operating systems handle process creation, scheduling algorithms, inter-process communication (IPC), and synchronization mechanisms to enable multitasking and concurrency.
Objectives
By the end of this chapter, you will:
- Define processes and understand their states (new, ready, running, waiting, terminated).
- Learn about process creation and termination mechanisms.
- Explore CPU scheduling strategies and how the OS selects which process to run.
- Understand thread management and its role in improving efficiency.
- Examine process synchronization techniques, such as semaphores and mutexes.
- Gain insights into Inter-Process Communication (IPC), including message passing and shared memory.
