Witryna28 gru 2024 · First Come First Serve (FCFS) FCFS is the simplest disk scheduling algorithm. As the name suggests, this algorithm entertains requests in the order they arrive in the disk queue. The algorithm looks very fair and there is no starvation (all requests are serviced sequentially) but generally, it does not provide the fastest service. WitrynaSize of bitmap = 1/ (4+1) = 1/5 of total main memory. Therefore, in this bitmap configuration, 1/5 of total main memory is wasted. 2. To identify any hole in the memory, the OS need to search the string of 0s in the bitmap. This searching takes a huge amount of time which makes the system inefficient to some extent.

Witrynanamei Algorithm • namei algorithm uses intermediate inodes as it parses a path name; call them working inodes. • The inode where the search starts is the first working mode. • During each iteration of the namei loop, the kernel makes sure that the working inode is indeed that of a directory.
