Which one is a difference between Cache and RAM?
A
Cache is nearer to the CPU than RAM
B
Cache is slower than RAM
C
Cache is cheaper than RAM than RAM
D
None of the above
Explanation: 

Detailed explanation-1: -CPU cache is built into the CPU or on an adjacent chip. Its memory access time reportedly is 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to the CPU request. RAM data access is faster than read-only memory and mechanical storage devices, such as hard disks and tape.

Detailed explanation-2: -The cache is faster, cheaper, and smaller than RAM. The cache memory caches CPU data and programs often and quickly. RAM contains the CPU’s current data and applications. The cache caches CPU-needed data and programs.

Detailed explanation-3: -Cache memory is sometimes called CPU (central processing unit) memory because it is typically integrated directly into the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.

Detailed explanation-4: -Basically, a cache stores temporary data and can be found on computers, phones, apps and web browsers. Cache memory also stores temporary data but is a physical computer component.
