Can anyone explain the difference between, Virtual RAM,VIDEO MEMORY, AND GRAPHICS MEMORY PLEASE.?
RAM is also called primary memory. It’s primary because on the motherboard, it sits right next to the CPU (the brains of the computer). When you open a program, the program instructions are fed from your hard disk into the RAM modules. These instructions are then queued up, like customers in a Macdonals restaurant, waiting to be processed by the CPU. Video memory, or VRAM as it’s also called, is memory that is allocated for rendering graphics and images (stuff you see on the screen, durr). Some computers don’t actually have VRAM (VRAM modules are seen on Video cards), so they use part of RAM to compensate. You may see some cheap budget computers that are advertised with “Shared Graphic Memory” or “Shared VRAM”. This means that the some of its primary RAM is being used as VRAM. Virtual memory is a computer system technique which gives an application program the impression that it has contiguous/continous working memory, while in fact it may be physically fragmented and may even overflow
