Detailed explanation-1: -Which of the following statements is correct about virtual memory? Explanation: Virtual memory is used to separate the user’s logical memory and actual physical memory. Therefore, option (b) is the correct answer.
Detailed explanation-2: -In computer science, thrashing occurs when a computer’s virtual memory resources are overused, leading to a constant state of paging and page faults, inhibiting most application-level processing. This causes the performance of the computer to degrade or collapse.
Detailed explanation-3: -Virtual memory is a feature of an operating system that enables a computer to be able to compensate for shortages of physical memory by transferring pages of data from random access memory to disk storage. This process is done temporarily and is designed to work as a combination of RAM and space on the hard disk.
Detailed explanation-4: -Detailed Solution. Virtual Memory consists of those addresses that may be generated by a processor during execution of a computation.
