FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -However, using virtual memory means the device will run slower than if it was using RAM. This is because the processor has to wait while the data is being swapped between the RAM and the hard disk. Secondary storage devices, such as a hard disk, have slower access times and can impair the device’s processing time.

Detailed explanation-2: -Virtual memory is always being used, even when the memory that is required by all running processes does not exceed the volume of RAM that is installed on the system.

Detailed explanation-3: -The bigger the virtual memory space, the bigger the adress table becomes in which is written, which virtual adress belongs to which physical adress. A big table can theoreticaly result in slower translation of the adresses and therefore in slower reading and writing speeds.

Detailed explanation-4: -If your virtual memory runs low, you will encounter the following message: Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied.

Detailed explanation-5: -If virtual memory doesn’t exist, we can’t load more than one program in the main memory. This means that without virtual memory, we can only run one program at a time. This is because each program might have to use different functions that may point to the same addresses in RAM.
