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.
Cache
Cache.
Cache
The memory that the computer processor accesses directly is primary memory. It is wired directly to the processor. RAM is primary memory on a computer.
yes. its think time for your computer.
its primary or main memory. all the programs(active or programs currently running on the processor) including operating system reside in RAM .
A megabyte is a unit of information storage equal to 8,388,608 bits. The cache buffer is an area of extremely fast-access memory used by the processor, so the larger the area, the more data could take advantage of this speed. The "difference" between the two is self-evident.

Memory is microchip; address are processor board slots
A buffer register is the simplest kind of register; all it does is store a digital information temporarily. It holds the contents of the memory which are to be transferred from memory to other components. By acting as a buffer, it allows the central processor and memory units to operate independently without being affected by minor differences in operation. See the related link for more information.
Cache memory is smaller and quicker, primary memory larger and slower.
Primary memory is the main memory of the computer. This is subdivided in to RAM (Ransdom access memory) and ROM ( Read-Only memory - used for storing loading instruections by manufacturer - BIOS ). RAM is used for temporary storage and volatile in nature. All datas will be get erased on power off. All instruction to the CPU is loaded in the main memory once the OS and applications are initaited . In between processor and main memory cache memory ( in-built in processor chip) to make the access speed fast.
