Operating Systems Essentials: From Process Scheduling to Kernel Architecture
Operating Systems Essentials: From Process Scheduling to Kernel Architecture An operating system coordinates hardware and software. It manages running programs, shares CPU time, and protects memory. Here are two core ideas every student should know: process scheduling and kernel architecture. Process scheduling decides who runs and when. A task can be a full program or a thread. The OS keeps ready tasks in a queue and selects one to run. It preempts running tasks to keep the system responsive and fair. Goals include fairness, quick responses, and efficient CPU use. Algorithms vary, but these are common examples: ...
