Process States: 5-State vs 7-State Swapping Models

Process States & The Swapping Lifecycle

In multitasking operating systems, processes continuously transition across lifecycle states governed by hardware interrupts, system calls, and schedulers.

⚡ The 3 Schedulers

• Long-Term Scheduler (LTS): Regulates multiprogramming degree.
• Short-Term Scheduler (STS): Decides CPU core dispatch.
• Medium-Term Scheduler (MTS): Manages virtual memory swapping.
