When the UNIX operating system was first introduced, the UNIX wizard himself Ken Thompson wrote the first file system. We will call that the “old UNIX file system”, and it was really simple. Basically, its data structures looked like this on the disk: The super block (S) contained information about the[r]

Thus far we have seen the development of two key operating system abstractions: the process, which is a virtualization of the CPU, and the address space, which is a virtualization of memory. In tandem, these two abstractions allow a program to run as if it is in its own private, isolated world; as i[r]

Introduction Years ago, IBM sold expensive mainframes to large organizations, and a problem arose: what if the organization wanted to run different operating systems on the machine at the same time? Some applications had been developed on one OS, and some on others, and thus the problem. As a soluti[r]
