A small amount (normally less than 1MB) of high-speed memory residing on or close to the CPU. Cache memory supplies the processor with the most frequently requested data and instructions. Level 1 cache (primary cache) is the cache closest to the processor. Level 2 cache (secondary cache) is the cache second closest to the processor and is usually on the motherboard.
AnswerA cache, in computer terms, is a place to store information that's faster than the place where the information is usually stored. Cache memory is fast memory that is used to hold the most recently accessed data in slower main memory. The idea is that frequently accessed data will stay in cache, which allows the CPU to access it more quickly, which means it doesn't have to wait for the data to arrive.
In reference to your processor, the Cache Memory is the Processor's internal quick-hand storage that it uses for things that it's currently processing at that given time.
As with most things, the more cache memory a processor has, it will usually run smoother and faster than one with less of about the same operating frequency.
Answerso cache makes it more fast than RAM, you know!!!
Pronounced cash, a special high-speed storagemechanism. It can be either a reserved section ofmain memory or an independent high-speed storage device. Two types of caching are commonly used inpersonal computers: memory caching and disk caching.
A memory cache, sometimes called a cache store orRAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because mostprograms access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM.
Some memory caches are built into the architectureof microprocessors. The Intel 80486 microprocessor, for example, contains an 8K memory cache, and the Pentium has a 16K cache. Such internal caches are often called Level 1 (L1) caches. Most modern PCs also come with external cache memory, called Level 2 (L2) caches. These caches sit between the CPU and the DRAM. Like L1 caches, L2 caches are composed of SRAM but they are much larger.

ANSWER
I would like to point out the disadvantage of the Cache...Just in case the Cache memory is full and data that is required to process or an application required to run doesn't fit into the Principle of Locality (that is not in the near by location) then it is obvious that the time required for the main memory to access the information would increase...coz first the the data need to be relocated into the cache and then process over here if the cache memory was missing it would be quicker...furthermore being such an extensive memories they are very small in Memory Size which requires location and relocation of the data or applications.
It allows commonly accessed data to be stored in full and referenced faster than recompiling the data each time.
Memory cache keeps data that is retrieved often in a separate area for faster retrieval.
cache memory is small,fast meory inserted between processer and main memory.
active segments of a program are placed in it. so processer can easily fetch it.
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.

No cache memory is not visible.....
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..
sram is used for cache for cache memory.
The maximum size of a cache memory is theoretically equal to the amount of primary memory(RAM).Like Cache only memory architecture where the whole memory space is filled up with the cache only.
Cache Memory is needed because Hardware implements cache as a block of memory for temporary storage likely to be used again.
Cache memory is smaller and quicker, primary memory larger and slower.
memory cache is on memory RAM, disk Cache is on the hard drive. They make things to get faster. For instance Google Earth use this disk cache to show you offline images.
l1 cache l2 cache
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
because cache memory is costlier than main memory and physical size of cache memory also matters.ignoring the cost , if we use large cache memory, it will take larger physical space.so mother board won't be able to accomodate it
