In deadlock avoidance using banker’s algorithm, what would be the consequence(s) of: (i) A process declaring its maximum need as maximum possible for each resource. In other words, if a resource A has 5 instances, then each process declares its maximum need as 5. (ii) A process declaring its minimum needs as maximum needs. For example, a process may need 2-5 instances of resource A. But it declares its maximum need as 2

Part B (10) Deadlock Avoidance Consider the following maximum-claim reusable resource system with four processes and three resource types. The maximum claim matrix is given by C [4 3 5 11 1 41 1 4 6 13 1 6] where Cij denote maximum claim of process i for resourcej. The total units of each resource type are given by the vector (5, 8, 15). The current allocation of resources is given by the matrix To 1 4] 2 0 1...

Write a C program for:
One technique for dealing with deadlock is called “detect and
recover.” In this scheme, some procedure is used
to identify when a deadlock occurs, and then another procedure
is used to deal with the blocked processes. One technique to
identify a deadlock is to maintain a resource graph that identifies
all processes, all resources, and the relationships between them
(that is, which processes exclusively own which resources, and
which processes are blocked waiting for which...

A system consists of 1 CPU, 1 Disk, and 1 Network Interface. A web server running on this system consists of a process that waits for an HTTP request. Once the request is received, the process services it by fetching the requested file from disk (an I/O operation) and then by sending the file content to the client. Assume that serving a request consists of the following phases: i. Process uses the CPU for 2 msec (parse request) // CPU...
