What is the objective of cache only memory architecture?
Cache memory is the high speed memories which are repeatedly requested by the Cache client (CPU). Whenever the requested data from the cpu is present in the cache, it directly supply the data and is known as cache hit(fast) and when the data is not accessible in cache then cache access the block of the main memory and feed to the CPU and it is termed as cache miss (slow).
What is an area of high speed memory that sits between the processor and the primary memory?
Cache.
Special high-speed memory built into the micro processor for the micro processors?
virtual memory
Why is it that the instructions being executed must be in physical memory of the computer?
When a computer gets ready to execute the next instruction, it pulls it out of memory of some sort or another. first it tries it's local high speed cache RAM, usually a part of the CPU chip. If it's not there, then it looks in the slower speed RAM. If it finds it there, the memory controller pulls a block of memory from RAM to cache then executes it there. If it doesn't see it in RAM, it looks for it in virtual memory, which is actually a part of the hard disk drive. When it finds it there, it pulls a block into RAM, then into Cache memory, where it is executed. Actually, the move from virtual memory to RAM is done way ahead of time, as the controllers see that the computer might need that block of memory in the near future. So you can see, all the instructions are executed in the small high speed cache RAM. This is done for speed. If all the instructions were executed in RAM, as computers once did, they would be 10 times slower. A lot of computer design is optimizing the memory controllers so that almost all of the instructions are executed out of high speed cache, and the processor rarely has to wait for the cache to fill up. If the computer executed out of hard disk space, it would be thousands of time slower.
Which type of memory is used for cache memory?
Usually high speed SRAM with CAM (content addressable memory) line address tags.
What is cache and what is its purpose?
Cache is a high speed memory which is basically used for the following reason: As the speed of the main memory is not as much as the speed of the CPU.so just to compensate the speed mistmatch between the CPU and main memory the cache is used in between the two.so whenever the CPU asks for any data its being checked with the cache memory and if present then "cache hit" occurs or else "cache miss" occurs wher the CPU takes the data form the main memory and that data's cpoy is being send to the cache for any further operation where the CPU can request for the same data.

What is special high speed memory that allows the processor to access data more rapidly than from memory located elsewhere on the system board?
cache memory
What is small high speed memory units used for storing temporary results?
A small high speed memory unit for storing temporary results is usually a register but can also be referred to as cache or a buffer
Why does the speed of a computer increase as soon as we increase the size of the cache memory?
Basically for the same reason that cache itself helps increase the speed. If there is more cache memory, the computer will have more information readily available, and there will be less cases where the information CAN'T be found in cache, and the CPU needs to access actual RAM, which is slower (or whatever other source of data the cache is supposed to speed up).
A buffer is an area of high speed memory that sits between the processor and the primary memory?
You should ask the question without the word "buffer" in the sentence. The correct statement would be; A Cache is an area of high speed memory that sits between the processor and the primary memory.
Where the constantly needed data is stored?
Constantly needed data is stored in RAM, and depending on the system and the CPU used, it may be stored in cache memory. Cache memory is a special, high-speed type of RAM. It is more expensive and uses more current than DRAM, but it is used where speed is critical. Cache memory is generally inside of the CPU these days.
Does microprocessor has a memory?
Some microprocessors have cache memory; this is high speed memory and, if you're lucky and a program is small, it may entirely run in cache memory. All microprocessors have memory as registers - these aren't memory in the conventional sense, but are temporary locations to store values being worked on, addresses in memory and so on.
