Top 10 List of Week 08

1. What is meant by CPU Burst and I/O Burst?
   In CPU scheduling, there is a basic concept which tells that its execution involves cycles, CPU and I/O burst. At first glance, I’m not really sure what both terms mean. Turns out it rather simple, just like the answer explained, which helps me understand more about CPU scheduling concept.

2. What is a Process in Operating System and what are the different states of a Process?
   CPU scheduling takes place when there’s a process such as waiting to ready, running to waiting, running to ready, and process terminates. This website explains those process states and other states aswell. I really like how the website define each state and provide picture and explanation on the process flow.

3. Preemptive and Non-Preemptive Scheduling
   This is a website thath explains the difference between Preemptive and Non-Preemptive scheduling. One of the key difference is the fact that non-preemptive needs to complete a process to move to another, while preemptive processes divide its process time with CPU cycle so there will be process that needs to hold on if the burst time exceeding CPU. I really like the website provides comparison table to help me distinguish both terms easier.

4. Operating System Scheduling algorithms
   A cheat sheet for scheduling algorithms that exists. The algorithms explained in “poin-poin”, rather than a long text which helps me point out the difference between and there’s also example on how to count wait time of each algorithms. Overall, a very good cheat sheet.

5. Cooperative vs. Preemptive: a quest to maximize concurrency power
   In this article, one part that I’ve found interesting for me is on Cooperative vs. Preemptive scheduling. It explains preemptive scheduling that not only to be seen in OS, but in real life application. There’s also several parts about Threading model and it’s relation with scheduling. Even though it’s a advanced article, I think it’s worth to check out.

6. Round Robin Scheduling Algorithm with Example
   One of scheduling algorithm that I’m having quite hard time to understand it is Round Robin. This website explains it very depth, from its definition to its advantage & disadvantage. I also think that step-by-step example really helpful to become understand.

7. Multiple Processor Systems - Computerphile
   This is a YouTube video that explains what multiple processor system looks and works like. Is multiple processor brings more advantages than single one? What are the motivation behind multiple processor? All of these question answered in this video, implicitly. I really enjoy watching it and it’s explained nicely.

8. Affinity dan Load Ballancing
   This is a website that explains about affinity and load balancing, that plays part in multiple processor scheduling. It’s explained briefly in Indonesia, making easier for me to read on. Also, there are other materials that related to multiple processor system which you guys could explore.

9. Computer System Architecture
   This is a YouTube video that explains every computer system architecture that’s avaliable. It also mention Symmetric and Asymmetric Multiprocessing. In that part, it’s explained briefly (2 minutes) with diagram schema, making it more understandable.

10. Process State Models in Operating System
    Besides process state definition, there’s also its model. In this website, you get to learn different kinds of state process model, up to seven state process model. Every model representated with diagram which helps to understand even more.
