What is the term for very fast memory used to store data or instructions between the CPU and regular memory?
Very fast memory used to store data or instructions between the CPU and regular memory is called cache.
What is the difference between main and auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing. Answered By: Richa Singh
Why Direct memory access has priority over the CPU when both request a memory transfer?
we can transfer data direct to and from memory without the need of the CPU. The transfer of data between a fast storage device such as magnetic disk and memory is often limited by the speed of the CPU. Removing the CPU from the path and letting the peripheral device manager the memory buses directly would improve the speed of transfer. This transfer technique is called direct memory access(DMA). During DMA transfer, the CPU is idle and has no control of the memory buses. A DMA controller takes over the buses to manage the transfer directly between the I/O device and memory. With Regards.

What are the memory storage area built into the CPU called?
registers
Define a system bus in a PC?
The bus between the CPU and memory on the motherboard. Also called the memory bus, front-side bus, local bus, or host bus.
What determines speed of computer?
Ram, free memory, if it is compressed, if it is defregmeted lately, what operating of system, what battery settings you have, your internet connection, the temp. of CPU and the processors.
When evaluating CPU memory do you check the cache memory?
The only memory on the CPU is cache memory and it is only dependent on the CPU type and generation you use.
How is data transferred between a CPU and RAM?
A memory management unit (MMU) is a small device between CPU and RAM recalculating the actual memory address, for example to provide an abstraction of virtual memory or other tasks.
What is auxiliary memory give an example of auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing. Some examples of auxiliary memory would be disks, external hard drives, USB drives, etc.
Why memory is kept near CPU in a digital computer?
Typically for faster transfer rates to the CPU (also notice that RAM is in between the CPU and the Hard drive connectors)
What allows a device to send data directly to memory by passing the CPU?
It's called DMA (Direct Memory Access)
In a typical computer system which component has the highest data transfer speed?
The path between the CPU and the RAM has the highest bandwidth. Or rather, the CPU to the memory controller, that is what's called the North Bridge. However, if you are looking at a single component then the CPU internal bandwidth is the tops.
