CPU Time and Scheduling

These flashcards cover key concepts related to CPU time management and scheduling decisions as discussed in the lecture.

Scheduler

A system that determines which process runs at a given time in a computer.

CPU Utilization

The percentage of CPU time spent on useful work versus system processes.

Processing Time (tp)

The amount of time allocated for a process scheduled to run on the CPU.

Scheduling Time (tsketch)

The time taken by the scheduler to execute and decide on process management.

Time Slice

The period allowed for a process to execute before the scheduler takes over.

Overhead

The time the CPU spends on system processing work like scheduling, rather than executing application processes.

Efficiency of CPU

The measure of how effectively the CPU is used for executing useful work versus system tasks.

Design Issues in Scheduling

Considerations like choosing appropriate time slices and metrics for scheduling decisions.
