An operating system uses a total of two units of the resource R for each of its three user processes. The operating system uses a total of 12 units of R. The absolute minimum number of R units that must be used to guarantee that there are no deadlocks is

Correctly arrange them in the order in which they are carried out to handle the interruption of a running user process by assigning a number from 1 through 9 to indicate the precedence order for the following steps.For example, 1 would indicate the first step in the process, 2 would indicate the second in theprocess and so on.

Three periodic processes of an operating system has P(burst time, period) as follows: P1(4,20), P2(6,10), P3(12,30). Which of the following is true when these processes are scheduled with Rate-Monotonic scheduling algorithm that assigns priorities proportional to periods (shorter period has higher priority). a)No process misses a deadline b)Only P3 misses its deadline c)P1, P2 and P3 all miss their deadlines d)P2 and P3 both miss their deadlines

An operating system has three user processes, and each of these processes consumes two units of the resource R. The operating system consumes a total of twelve units via R. The absolute minimum number of R units required to preclude the chance of deadlocks occurring is

Im having trouble with this assignments and all the Chegg answers are wrong All present-day operating systems are equipped with the capability to allocate memory to users dynamically (at run time). This feature allows multiple user programs to coexist in the main memory and run virtually at the same time by sharing system resources like CPU, memory, etc. In this assignment, you are required to design and implement in MIPS a project for dynamic allocation and deallocation of memory on user demand. However, you can make the following simplifying assumptions: The memory pool is limited to 4096 bytes The memory pool divided into equal chunks of 32 bytes (chosen due to MIPS architecture). Thus, the 4096 bytes memory will be divided into 128 chunks. Despite allocation requests coming in any size, the actual allocations should be performed in integer multiples of chunks. Therefore, the byte size request will be rounded up to the closest multiple of 32. To succeed in this task, the code must…

A multicore processor with 4 cores has 15 attached ta pe drives. There is a large number of jobs submitted to the system that each requires exactly 4 tape drives to complete execution. Assume that each job runs on 4 tapes for the entire duration of its execution. Also assume an endless supply of such jobs. The scheduler in the operating system will not start a job unless there are 4 tape drives available. When a job is started, 4 drives are utilized immediately for its execution and are not released until the job finishes. a) What is the maximum number of jobs that can be in progress at once? b) What are the maximum and minimum number of tape drives that may be left idle at a given time as a result of this policy?
