Facts: Facts about Deadlock Deadlock is a situation that occurs in OS when any process enters a waiting state because another waiting process is holding the demanded resource. Deadlock is a common problem in multi-processing where several processes share a specific type of mutually exclusive resource known as a soft lock or software. Deadlock is a situation where a process or a set of processes is blocked, waiting for some other resource that is held by some other waiting process. It is an undesirable state of the system. The following are the four conditions that must hold simultaneously (Links to an external site.) for a deadlock to occur. Mutual Exclusion –A resource can be used by only one process at a time. If another process requests for that resource then the requesting process must be delayed until the resource has been released. Hold and wait –Some processes must be holding some resources in nonshareable mode and at the same time must be waiting to acquire some more…

Assignment description: When an operating system has been running for a while without reboot, and more it keeps allocating and de- allocating pages, the quicker the memory becomes fragmented. And the kernel may not always be able to defragment enough memory for a requested size on time. If that happens, applications may not be able to allocate larger contiguous chunks of memory even though there is enough free memory available. Being a system admin and considering the following scenario, discuss the current proposed solutions to solve the problem caused in this case and critically analyze the performance of the proposed solutions to solve the problem. Provide a report considering the following outlines. Scenario: In the following snapshot of running operating system, we can see that there is a free memory space equal to (55 KB). Assume that new process (process#07) needs to be run inside the memory and required 50 KB but the memory (fragment) is not contiguous. Assigned Space Assigned…

Your task is to design an operating system for the Little Man Computer so that several programs can run concurrently. How would you modify the above diagram for this to occur? You will be graded on using operating systems principles and you should cover such concepts as concurrency, state saving, time slicing, and priority.

According to your research, in what ways can the principle of Mutual Exclusion (ME), from all perspectives (that is, within the scope of your studies), be regarded as a necessary framework for the effective operation of an operating system?

Scheduling is a method that is used to distribute valuable computing resources, usually processor time, bandwidth, and memory, to the various processes, threads, data flows and applications that need them. Scheduling is done to balance the load on the system and ensure equal distribution of resources and give some prioritization according to set rules. This ensures that a computer system is able to serve all requests and achieve a certain quality of service. With this regard, Discuss the usefulness of Gantt charts in the scheduling process.
Based on your findings, to what extent do you think the idea of Mutual Exclusion (ME) is necessary for the effective running of an operating system?
Modern Operating Systems must tackle the challenges of Synchronization and Deadlock. ’Process Synchronization’ is the task of coordinating the execution of processes in a way that no two processes can have access to the same shared data or resource. A process requesting a resource may have to wait, if the resource is not available at that time. Sometimes, a waiting process is never able to change state, because the resources it has requested are held by other waiting processes; this situation is called ’Deadlock'.

In concurrent programming, a "critical section" is a part of a multi-process program thatmay not be concurrently executed by more than one of the program's thread.
