RAM
cache memory
Frequently accessed data is often stored in a cache memory, which is a smaller, faster type of memory that sits between the main memory (RAM) and the processor. Caching helps improve performance by allowing the processor to access frequently used data more quickly than if it had to retrieve it from the main memory every time.
I think you are referring to what is called cache memory. (rhymes with 'cash') Cache is a portion of computer memory reserved for frequently used information, so that the information can be accessed more rapidly than retrieving it from the hard drive, or from the 'regular memory'
You cannot buy more memory for a processor. You can however buy memory for your computer. More memory means a faster computer, but suffers from diminishing returns.
yes
controller performs its operations faster than processor because controller has memory in it so it takes less time cycles for fetching of address or data from memory where as in processor memory is connected externally so time taken will be more to perform its operations.

No. Each processor core is 3.2gHz. The bottleneck is the bus interface, but the compromise is that each core tends to spend more time executing instructions than accessing memory. Even so, L1 and L2 cache improves the situation by caching memory, so you get the best of both worlds. If, however, all the cores randomly accessed wide areas of memory, performance would suffer.
Processing speed is far more important than cache size. Cache is a small amount of memory located in, or around the processor that is used to store small amounts of information that the processor can refer to as a quick reference. There are millions of bits flowing through cache memory every time the processor works. Any more, there is a standard amount of cache memory that is in every processor. Speed is a totally different thing and almost has nothing to do with cache size. Speed is definitely more important.
Memory is more important than the type of processor. Unless you are about to run programs like photoshop or premier pro or in Apple's case, Final Cut Pro, then you probably want the Core i5. A memory upgrade is easy and it is cheap. Do it yourself instead of letting the factory install it for you. It will save you a good amount of money. But for most people, Core i3 with 6 GB of memory is better. For more answers like this, go to jamesrealtech.com
