The CPU and memory are located on the: 1). Storage and memory differ with respect to which of the following characteristics? System software is the set of programs that enables your computer's hardware devices and software to work together.

The only memory located on a computers CPU chip is called thecache. Typically about 1-8MB in size it acts as a rapid access'buffer' for immediate actions.The main memory is usually termed the RAM and sit's nexto theCentralProcessorUnit - connected by the FrontSideBus (boardcircuitry), size. Well depending on age anything from a few MBto 16GB (dependant on a number of factors).Actually, the term 'main memory' is reserved for the primarylocation where active work is stored. In modern computers, 'mainmemory' consists of DRAM chips mounted somewhere near the CPU.Thus, 'main memory' is never on chip. The reason for this iscost - providing memory inside the CPU is hideously expensive,there is a limit to how much can be put there, and the amount cannever change. Off-chip main memory allows very significant costsavings, and allows the amount of memory to be adjusted freely.There are generally TWO types of memory that are locatedon-chip, however. Cache memory (which can come in various 'levels',describing how far away from the main CPU each memory bank is) isused to keep copies of data from the main memory in a location thatis 'closer' to the CPU, and thus faster to access and use.Registers are memory located directly inside the CPU's executionunits - think of them as scratch space where the CPU cantemporarily store small amounts of data while it does acalculation.

For instance, if a CPU is asked to do: A+B=C, it willhave to load A into a register, then load B into a register, thendo the calculation, saving the result into a register, then finallyload the 'results' register value back into C.
