A single processor system has three resource types X, Y and Z, which are shared by three processes. There are 5 units of each resource type. Consider the following scenario, where the column alloc denotes the number of units of each resource type allocated to each process, and the column request denotes the number of units of each resource type requested by a process in order to complete execution. Which of these processes will finish LAST?

Consider a disk pack with 16 surfaces, 128 tracks per surface and 256 sectors per track. 512 bytes of data are stored in a bit serial manner in a sector. The capacity of the disk pack and the number of bits required to specify a particular sector in the disk are respectively:

Group-1 contains some $$CPU$$ scheduling algorithms and Group-2 contains some applications. Match entries in Group-1 to entries in Group-2.

Group-1
(P) Gang Scheduling
(Q) Rate Monotonic Scheduling
(R) Fair Share Scheduling

Group-2
(1) Guaranteed Scheduling
(2) Real-time Scheduling
(3) Thread Scheduling
