Yes, Onboard L1 and L2 cache is accessed much quicker than system ram.
A cache is intended to speed things up. The larger the cache, the slower it performs. If it becomes slower to access the cache than the memory itself, it defeats the purpose of having a cache.
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory. Cache Memory generally comes in smaller size (3MB, 6MB etc) than the RAM (512 MB, 1GB,2GB.....)

A resounding "sort of!" You could, but it would defeat the point of having a cache to begin with.Physically, the cache(s) of a computer is (are) located closer to the CPU than the RAM - so even if you replaced the RAM with a higher-speed memory, the part that was further away from the CPU would take longer to access than the part that was closer (although the difference would be very small). Cache is also much more expensive than RAM to create, although that doesn't mean it's impossible, and the speed of access is still limited by the speed of the FSB (Front Side Bus). Although cache may have a faster access time than RAM, it is not efficient (cost-wise, at least!) to simply cache everything because you don't necessarily need to use everything right away all the time - cache exists to give you faster access to time-expensive data that you use often. It could get to the point where even your cache would need cache!
Many CPUs have what is known as a CPU cache. The function of this CPU cache is to speed up access to data.
No, a cache memory is often used to store data that has been needed recently on grounds that it will be faster to access when/if it is needed again. When data that is requested is contained in the cache you have a cache hit, and when you have to retrieve it from the hard drive (or where ever its original storage was) again it is called a cache miss. Retrieving data from the hard drive is slower than retrieving it from the cache.
Cache simply is for speeding up the processes already completed, since it is faster than ram, and easier to access. it basically is just for speeding up applications you use often. cache is volatile meaning that it is erased when you turn off your computer.
The Level 3 (L3) cache has the highest latency. The CPU cache is memory that is used to decrease the time that it takes the CPU to access data. Because the data is cached, it can be accessed more quickly. The CPU cache is often found directly on the CPU or built into the CPU. The L3 cache is usually larger than the L1 and L2 cache, but it is searched last. The CPU searches for data in the following order: L1 cache, L2 cache, L3 cache, RAM.
Yes.
cache
Cache is faster than RAM...
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
