MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A computer’s MMU manages virtual memory operations. In most computers, the MMU hardware is integrated into the central processing unit (CPU). The CPU also generates the virtual address space. In general, virtual memory is either paged or segmented.

Detailed explanation-2: -RAM is given the term ‘random access’ because data and instructions can be stored and accessed from any location within the memory ). RAM is used to hold data and instructions that are currently in use. In a modern PC, RAM is used to hold the operating system and any open documents and programs that are running.

Detailed explanation-3: -RAM (random access memory) is a computer’s short-term memory, where the data that the processor is currently using is stored. Your computer can access RAM memory much faster than data on a hard disk, SSD, or other long-term storage device, which is why RAM capacity is critical for system performance.

Detailed explanation-4: -Paging is a storage mechanism used in OS to retrieve processes from secondary storage to the main memory as pages.
