Waht is cache memory?
Answer:
Hello:
The idea at the rear a cache is to have major, repeatedly accessed information available surrounded by a fast RAM-type memory to be precise specific to disk I/O operations. Having some of the repeatedly access data surrounded by RAM is faster than having to fetch it from disk over and over again. L1 cache is used surrounded by a microprocessor for data and repeated instructions. L2 cache is special RAM on a bus on the motherboard for use by more than simply the microprocessor- it can be used by file system operation (disk I/O) directly. L3 cache is simply what L2 used to be...now that more and more processors are incorporating some horizontal of L2 cache directly on board.
Hope this help!
Cheers!

cache memory is remembering how much money you had when you not here the bar. Then wake up and realizing you be WAY off and cant afford a breakfast at Denny's
cache is simply a temp memory storage, mostly for CPU's that can hold instructions. L1 is built into the CPU, most newer CPU's enjoy small amounts. L2 is external and i usually very big. L3 is even more memory built contained by between the CPU and the RAM.
Cache memory is a small bank of faster memory typically located outstandingly close to or within a CPU. Its role is to buffer the most recent access to RAM so that if the data is requested again, the CPU doesn't enjoy to wait extra time to find the data from RAM (which is largely much slower than getting it from cache).
The number of levels of cache depends on how the hardware designers implement it. No levels of caching are required to generate a computer work, but they certainly do backing quite a bit. Most modern computers hold at least two level of cache, especially multi-core processors which generally hold a small cache per CPU core and a larger, but slower cache which is shared by all of the CPUs.
