Caches are meant to improve memory access performance of the computer system.
There are hardware caches implemented as well software caching is also done in Operating system to improve performance.

Is cache memory necessary?
The cache memory is used to store the frequently used data in the main memory in order to avoid the elapse of the seek time taken to read that data in the main memory.. So, to improve the performance of a PC, its necessary to have cache memory.
Cache memory does not affect the performance of the CPU?
true
Is cache a block of high speed memory?
Yes ,i think cache memory is very fast memory in conputer system.
What are the type of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
Is cache memory is the main memory of cmputer system?
NO...The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.Thus Cache memory is not main memory of computer system.--- form Wiki
What cache typically has the most memory?
Caches are generally defined as L1, L2, and L3. If a CPU has any cache memory at all, it will have at least L1 cache. L1 cache is the fastest, and most expensive, type of cache memory. Usually CPUs will only have a very small amount of L1. L2 is typically larger, less expensive, and slower than L1. L3 is less expensive, larger, and slower than L1 or L2, if present. All three levels of cache memory are magnitudes faster than system memory. Systems withequivalenthardware, including CPUs will identical speeds, will perform better at certain tasks when more cache memory is present, with L1 cache adding the most performance boost.
What are the two types of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
What to do to not damge your cache memory for RuneScape?
"Damaging" the RuneScape cache on your computer does nothing. I frequently delete it to refresh the data which in turns boosts performance.
What is the impact of cache miss on system performance?
A cache miss is where the processor requests a memory transfer, and that data is not in cache. This requires the bus interface unit to perform a slow access to memory, as opposed to a fast access to cache, or it requires the cache manager to make disk accesses, which can be millions of times slower than main memory. Depending on the cache level, a consistently high percentage of cache misses can impact performance significantly. This is most often seen in low physical memory machines, where the swap file hit-miss ratio is poor. The working set is the memory that is most recently used. Ideally, you want short-term working set to always be smaller than physical memory. Since working set is hard to measure, you can use commit charge, though that is not as accurate. You want commit charge for currently active applications plus kernel memory to be less than physical memory.
Special high-speed memory built into the micro processor for the micro processors?
virtual memory
What is the purpose of the registers and cache memory in the computer system?
The register is a collection of different settings and configurations for the operating system. Cache memory is a way for the computer to load webpages faster by storing them in RAM.
Which memory is optional to start a computer system?
Random access memory (ram)
