It is used to temporarily hold data and instructions that the processor is likely to reuse.

WebCache and Registers are the data holding places on your CPU. Fundamentally they have the same purpose, yet they function differently. The main differences lie in their data access speeds and capacity. Without them, the CPU would take a long time to process single streams of instructions. WebA register may hold a piece of data, like a storage address and computer instruction. Cache. Most of today’s computers improve processing times with cache (pronounced cash). Two types of cache are memory cache and disk cache. Memory cache helps speed the processes of the computer because it stores frequently used instructions and data.

WebSep 26, 2014 · Sorted by: 14. Registers are very, very expensive because they have to be very, very fast and they need to be accessed from many places simultaneously. For example if you have statements a = a + x; b = b + x; c = c + x; you have three instructions which all want to read the same register. So the register is not just the memory.
