WebCache technology is the use of a faster but smaller memory type to accelerate a slower but larger memory type. When using a cache, you must check the cache to see if an item is in there. If it is there, it's called a cache hit. If not, it is called a cache miss and the computer must wait for a round trip from the larger, slower memory area. Web18 de jan. de 2013 · Sorted by: 1.
