In UNIX directories are treated as files, in fact a directory is a file. Directories have permissions associated with them as do files.
Consider a system such as a System V-based UNIX system, in which a process can have exactly one group identity. To change groups,users must execute the newgrp command. Do these groups differ
Suppose a flash storage device is used instead of a disk, and it has a seek time of 1 microsecond, and a transfer rate of 40 megabytes per second.
You are using a 1 GHz system with paged virtual memory for doing a real-time application. No other application is running on the system.
Suppose you have a operating system that uses pure segmentation on a computer with 1Mb of physical memory. A series of programs are executed on this computer, performing the following series of alloca
A computer has 16 pages of virtual address space but only four physical pages. Initially the physical memory is empty. A program references the virtual pages in the order 0, 2, 4, 5, 2, 4, 3, 11, 2, 1
Multiple speeds are computed in the MAC layer. A forwarder with the highest speed is selected on MAC layer feedback. This selection may not produce a shortest path. Explain why SPEED uses th
