Best Answer

The term 'random access' is used because this kind of memory cn be accessed directly (in any order) if a cell's address is given. Only data stored in RAM can be manipulated,thereforeevery program that needs to be executed must be place in the main memory. The amount of main memory is crucial because it determines how many programs can be executed at the same time. The larger the amount of RAM the better the computer response.

What is the purpose for vram?

VRAM (Video Random Access Memory) is a type of memory specifically designed for storing graphical data used by the computer's display device. It helps to improve the performance of graphics-intensive tasks, such as gaming or video editing, by providing high-speed access to images and textures. Without sufficient VRAM, the computer may struggle to display complex visuals smoothly.
