Differentiate Between cache memory and main memory??
Answers
Cache memory is a high speed memory that is used to store frequently accessed data. Whenever it is required, this data is made available to the Central processing unit at a rapid rate. Main memory is also known as Random Access Memory. It is a memory unit that directly interacts with the central processing unit (CPU).
Answer: 1. Random Access Memory (RAM) :
Random Access Memory (RAM) is used to store the programs and data being used by the CPU in real-time. The data on the random access memory can be read, written, and erased any number of times. RAM is a hardware element where the data being currently used is stored. It is a volatile memory. Two types of RAM are Static RAM, or (SRAM) and Dynamic RAM, or (DRAM).
2. Cache Memory :
Cache is a smaller and fast memory component in the computer which is inserted between the CPU and the main memory. To make this arrangement effective. The cache needs to be much faster than main memory. This approach is more economical than the use of fast memory devices to implement the entire main memory.
