COMPUTER FUNDAMENTALS

Detailed explanation-1: -However, users should not overly rely on virtual memory, since it is considerably slower than RAM. If the OS has to swap data between virtual memory and RAM too often, the computer will begin to slow down–this is called thrashing.

Detailed explanation-2: -There are times when the amount of RAM needed to hold all running programs and data is greater than the amount of RAM available to the computer. When this happens, part of the computer’s secondary storage, such as the hard disk, can be used to store data temporarily.

Detailed explanation-3: -VM can only be too high if its taking space from the drive and you need it back. Setting a max and min VM size the same ie, 2400mb min 2400mb max, the system will not waste resources altering the page file and the system will be slightly faster.

Detailed explanation-4: -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.

Detailed explanation-5: -What is Virtual RAM in Android mobile phone? Virtual RAM is a technique in which a small portion of the internal storage (ROM) is set aside and added to the RAM of the device, thus effectively increasing the number of tasks and processes that can be run in the background.
