Introduction to Operating Systems Processes - Revised
Description
A process is a program that is under execution. This course will begin by showing you how a process is stored in memory. You will learn how a kernel keeps some metadata corresponding to each process in the RAM. You will also study how to convert from a kernel virtual address to a kernel physical address in RAM by subtracting MAX_SIZE or by adding MAX_SIZE. The course will also discuss the User stack and the Kernel space stack.
Next, you will look into the Process Control Block(PCB). In order to create a process, operating systems use a technique called cloning, which in turn uses a system call Fork. You will learn how a fork creates a copy of the kernel metadata, Process Control Block, and page table kernel stack. The course will then discuss Zombies, xv6 systems, and allocproc. Finally, you will study EMBRYO, the copyuvm, and the six things that happen in xv6 when the system call exit gets executed.
This online course is part of a series of courses on computer operating systems, and you will need to have taken the 'Introduction to Operating Systems' and 'Introduction to Memory Management' courses prior to this one. Computer operating systems are a complex but exciting subject to study, and once you have gained some vital knowledge in this area your résumé will become a lot more impressive to potential employers. So why wait? Keep up your learning journey, today.
