Isolation mechanisms

This lecture covers the concept of isolation mechanisms in operating systems, focusing on the unit of isolation known as 'Process'. It explains how isolation enforces separation to constrain failure effects, prevents processes from interfering with each other or the operating system, and discusses hardware isolation in x86 architecture. The lecture also delves into system calls in xv6, the process of switching rings in x86, and the implementation of isolation mechanisms to prevent malicious processes from causing harm.
