What does cache memory mean?
cache memory is just the same as RAM only it is much much faster. This is why there usually isn’t much cache because since it is faster, it is far
more pricey than standard RAM. Your cache is like golden ram and used to store things that are going to be accessed more than once, or need
to be accessed quickly. Just like RAM, once the program is done or once you turn your computer off it is a clean slate and ready to be used again.
