Topic notes
GATE evaluates the 'Processes' topic primarily through the standard 5-state process lifecycle (New, Ready, Running, Blocked/Waiting, Terminated) and the valid/invalid transitions between these states. Questions consistently test the exact path of a process during execution, preemption, and I/O invocation. Recent trends show a progression from purely theoretical transition checks (MCQ/MSQ) to procedural tracing of state changes in C code execution (NAT).
