Consider a computer system with five memory partitions of 300 KB, 400 KB, 200 KB, 100 KB, and 500 KB (in order), and four processes of 212 KB, 417 KB, 112 KB, and 326 KB (in order). a.

Suppose we have a system with 50 active processes, P0, P1, ..., P49, some user processes, and some kernel processes. For simplicity, we are not concerned with threads in this question. Ready processes are scheduled to Run by some scheduler. The scheduling algorithm does not matter here. Suppose process P13 makes a disk_read() operating system call. Assume that the completion of disk transfer is signalled by an interrupt from the disk controller. Trace as accurately as you can what happens in the CPU (not the disk) until process P13 has received its requested information from the disk. Hints: The question is about interrupt handling I am looking for a trace of what processes run, why, and what they do. I am not looking for instruction-level explanations. I am not looking for a discussion of disk access, operation, or transfer.
An operating system follows a variable memory partitioning model. The system keeps track Question 31 of empty blocks in a linked list in the order of their address, where each node stores the size of next empty block in the memory. Say that current state of the memory is hold by the linked list shown below, which tells that there are currently four empty blocks in the memory, and the size of first block is 12 byte etc. 12 8 3 Assume that following memory block requests have been made in given order: 8 bytes, 2 bytes and 6 bytes. Draw the linked list to be changed after each block assignment by the following strategies; (a) First Fit (a) Best Fit
Computer Science 17. Tree-structured directory design does not allow us to create links for a file or folder. Group of answer choices True/False 18. With the same amount of total data access, processes with larger working sets tend to run faster. True/False 19. A cache miss means that the requested data is not stored in the cache and must be fetched from the hard drive before the program can proceed.
In an operating system, what does "partitioning" mean? Make a list of their strong and weak points.The pace is unclear. A process must remain in main memory in order to function. External Fragmentation occurs as a consequence.

The principal advantage is a savings in physical memory space. This occurs for two reasons: (1) a user page table can be paged in to memory only when it is needed. (2) The operating system can allocate user page tables dynamically, creating one only when the process is created. Of course, there is a disadvantage: address translation requires extra work.
