hi compused
Cache memory is small memory that is extremely fast. Whilst RAM is your main memory, cache is much much quicker and also very expensive. This is why computers come with very little cache memory as opposed to RAM. Basically, cache stores the data from the most frequently used parts of your RAM. Instead of the processor trying to access the data from RAM, it checks whether it is stored in cache first (as this is faster memory). If it is stored there, it reads directly from cache, thus making processing time faster. Therefore, the more cache you have, the better. If it wasn't so expensive to manufacture, computers would work only with cache. Hope this helps you a little bit.
