Buddy system of memory allocation Free memory is used to maintain in linked lists, each of similar sized blocks. Every block is of size 2^k. When some memory is needed by a th
File structure Certain files must conform to a needed structure that is understood by the operating system. The operating system may consist that an executable file has a parti
With software algorithms for mutual exclusion, such as Dekker's algorithm, Peterson's algorithm, or Lamport's bakery algorithm, note that optimizing compilers and out-of-order exec
Q. Consider a file at present consisting of 100 blocks. Presume that the file control block (and the index block in the case of indexed allocation) is already in memory. Compute h
Q. Several CPU-scheduling algorithms are parameterized for instance the RR algorithm requires a parameter to indicate the time slice. Multilevel response queues require parameters
What are overlays? To enable a process to be larger than the amount of memory allocated to it, overlays are used. The idea of overlays is to keep in memory only those instructi
