Week 5. CPU Scheduling
AI is pulling out the key ideas
Summary
- CPU scheduling picks which process in the ready queue runs on the CPU next.
- FCFS is simple, but short jobs stuck behind a long one wait a long time (the convoy effect).
- SJF gives the shortest average wait, but needs to know the next job's length in advance.
- Round Robin takes turns one time quantum at a time, keeping response times short and even.
Keywords
Flashcard
What is the biggest drawback of SJF scheduling?
Answer
The next job's CPU time is hard to know in advance, and long jobs can keep getting pushed back until they starve.

Frequently asked questions
Who is IFF AI for?
High school, college and university students, people preparing for professional certifications, and anyone learning from slides, PDFs or course notes. You need to be 14 or older to create an account, and if you're under 18, ask a parent or guardian before buying PRO.
Which files and languages are supported?
You can upload PDF, PowerPoint (.pptx) and Word (.docx) files. Study notes are built from your document's own text, so they come out in the language it's written in. The app itself is available in English and Korean.
Are the practice questions real past exam questions?
No. Quizzes and practice questions are newly generated from the materials you upload. We don't provide or sell real or leaked questions from any exam, and we can't guarantee scores or results.
What can I upload, and who can see it?
Upload material you have the right to use, like your own notes or course material from your classes. Your uploads are private to you and are never shared or sold.
Are the AI results always accurate?
AI output can contain mistakes. Summaries don't replace the original, so double-check anything important against your source material.
How do cancellation and refunds work?
You can cancel anytime. If you haven't used PRO within 7 days of paying, you get a full refund. If you have, we refund the remaining amount minus the days used (at the monthly price) and a 10% cancellation fee. See our refund policy for details.
