What technology of memory is Cache RAM usually?
A. DRAM
B. Flash
C. SRAM
D. EEPROM
E. PROM
Answer: Option C
Solution(By Examveda Team)
A memory cache, sometimes called a cache store or RAM 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 most programs access the same data or instructions over and over.This Question Belongs to Computer Fundamentals >> Computer Fundamental Miscellaneous

Static random-access memory (static RAM or SRAM) is a type of semiconductor random-access memory (RAM) that uses bistable latching circuitry (flip-flop) to store each bit. SRAM exhibits data remanence,[1] but it is still volatile in the conventional sense that data is eventually lost when the memory is not powered.
The term static differentiates SRAM from DRAM (dynamic random-access memory) which must be periodically refreshed. SRAM is faster and more expensive than DRAM; it is typically used for CPU cache while DRAM is used for a computer's main memory.
sram is faster than flash memory hence used in cache memory
Cache memory, also called CPU memory, is high-speed static random access memory (SRAM) that a computer microprocessor can access more quickly than it can access regular random access memory (RAM). ... Cache memory is responsible for speeding up computer operations and processing.
