SoC 101 - Lecture 7d: Scheduling (Processes and Threads)

System-on-Chip 101
or
"Everything you wanted to know about a computer but were afraid to ask"
This is Lecture 7 of my "SoC 101" course at Bar-Ilan University. In this course, I provide an overview of computer hardware engineering and SoC design, covering the full stack from the basic terminology, through computer architecture, and up to low-level software and design methodologies. The purpose of this course is to methodologically tell you about all those things that you may not have heard during your engineering studies and "fill the gaps" between the parts that you learned in-depth. It is in no way intended to provide a full, detailed description of every concept introduced, but following the course will give you a good idea about how a computer or any embedded system actually works.
Lecture 7 moves from the hardware into the software with an overview of the main concepts of Operating Systems and how they affect and are affected by the underlying hardware. The lecture starts with the basics of operating systems - what they are, why we need them, and a lot of the confusing terminology that "Linux Geeks" use all the time. The lecture continues with a focus on three of the main jobs that the OS carries out: Interfacing (Interrupts), Scheduling (Processes and Threads) and Synchronization/Protection. To finish this extended introduction to operating systems, the final chapter takes a look at the type of OS you would commonly find running on embedded systems, the RTOS.

can you given an example or threads, like you mentioned for process, each tab in a browser is a process. And can there be user and kernel process?
