Can 2 different processes have virtual memory addresses that reference the same physical memory addresses? Explain your answer
Step by step
Solved in 2 steps
- What is the difference between virtual memory addresses and physical memory addresses when it comes to memory addresses? Which of the two is the larger? Why? What are the pros and downsides of using virtual memory?What's the difference between 1/O-bound, CPU-bound, and memory-bound processes?Memory address translation is useful only if the total size of virtual memory (summed over all processes) needs to be larger than physical memory. True or False. Justify your answer.
- 3. Give a yes/no answer, along with an explanation, to the following questions: (a) In a multi-core system, there can only be one process running for a given executable. (b) Two processes generally access the same address space. (c) Two processes having shared access to part of a computer's memory see that shared part of the memory at the same address. (d) Two threads can communicate through memory they share. (e) An executable, run two times consecutively, will result in two processes that see the exactly the same address space each time, with pointers having the same numerical value for each run.Does every process have the same mapping of virtual memory addresses to physical addresses? Explain your answer.Please let me know if these are true or false! In multiprocessors with a shared physical main memory, an access to a word of main memory always takes about the same amount of time no matter which word is being accessed and by which processor: T/F? When reading data from a magnetic disk, the rotational latency increases linearly with the size of the request: T/F? SSD is faster to access than magnetic disk, but slower than DRAM main memory: T/F? The primary purpose of RAID is for data backups: T/F? Typically, data parallelism offers greater opportunities for achieving highly-parallel execution than does functional parallelism: T/F? In MIPS systems, one way to implement locks is with the MIPS test-and-set machine language instruction: T/F?
- Are there distinctions between associative and normal memory, or are they both the same? Which option is more costly, and why?Explore the advantages and trade-offs of using various memory access patterns, such as row-major vs. column-major, in different computing scenarios.To put it simply, this is an explanation of dynamic memory allocation.
