Inside Operating Systems: How Scheduling, Memory, and I/O Work Together
Inside Operating Systems: How Scheduling, Memory, and I/O Work Together Computers run many tasks at once. The operating system coordinates three main resources: CPU time, memory, and I/O devices. When these parts work well together, apps feel fast and smooth. If one part slows down, the whole system can feel sluggish. The collaboration among scheduling, memory management, and I/O control is the secret behind responsive software. Scheduling the CPU The CPU scheduler decides which task runs next. The ready queue holds processes and threads waiting for CPU time. The kernel uses rules like time slices and priorities to switch tasks without freezing. This gives many apps a fair share of CPU time. The goal is quick replies and steady progress. ...
