Bankers algorithm: The Resource allocation graph algorithm isn't applicable to a resource allocation system with multiple instances of every resource type .This algorithm isn't as efficient as the above one .It's so called thus because this algorithm is used in banking system to ensure that the bank never allocated its available cash in such a way that it could no longer satisfy the needs of all its customer. In this algorithm there subsist matrices to hold the needed, available and allocated resources.
What are three conditions that a solution for the critical section problem must satisfy? The three conditions are as following:- a) Mutual exclusion :- if a process is
Memory Protection
For the first assignment you are required to construct a logic circuit onto a copper clad circuit board (vero board). This construction will require the use of planning the positio
How many disk operations are needed to fetch the i-node for the file /usr/ast/courses/os/handout.t? Assume that the i-node for the root directory is in memory, but nothing else alo
Synchronization can be achieved by means other than locks and condition variables. One alternative is semaphores. A semaphore is used to regulate traf?c in a critical section. A se

Operating Systems have evolved tremendously in the last few decades. The first approach for building Operating Systems, taken during the 40s through early 60s, was to allow only on
4. Describe priority scheduling algorithm. Consider the following set of processes. Show the order in which the algorithm will schedule these processes. Assume preemptive and non-p
Since each thread has its own processing space therefore communication between threads will need to be done through a common global variable. Since multiple threads can access the
