WebSo we can say that processor can access registers faster than the main memory. The register is measured in bits like a processor may have 16-bit, 32-bit, or 64-bit registers. The number of register bits specifies the speed and power of CPU. For example, a CPU which has 32-bit register can access the 32-bit instructions at a time.

WebJun 6, 2016 · Main memory is the end of the line – if asked for data it does not have, it does not look elsewhere for it. Data can survive in registers, caches, and main memory while the computer has power. Beyond the main memory are devices where data can survive when a computer loses power. These devices can usually hold more data than main memory. WebMar 17, 2010 · Update: Please, I know that registers are faster than RAM and other types of cache.

WebNov 1, 2024 · Because primary memory is an internal memory of the computer, accessing data from this memory is faster. This memory is the most volatile because the data in primary memory does not reside if data is not saved when a power cut occurs. Primary memory is costlier as compared with secondary memory. Its capacity is very much … WebAuxiliary memory is much larger in size than main memory but is slower. It normally stores system programs, instruction and data files. It is also known as secondary memory. It can also be used as an overflow/virtual memory in case the main memory capacity has been exceeded.
