JAMIA 2024 — Computer PYQ
JAMIA | Computer | 2024What is the high speed memory between the main memory and the CPU called?
Choose the correct answer:
- A.
Register Memory
- B.
Cache Memory
(Correct Answer) - C.
Storage Memory
- D.
Virtual Memory
Cache Memory
Explanation
Mathematical Representation
In computer architecture, the hierarchy and access relationship can be represented as:
CPU⟷Cache Memory⟷Main Memory (RAM)
The performance benefit is often explained by the Hit Ratio (H):
H=Total Number of Memory AccessesNumber of Cache Hits
The Average Memory Access Time (Tavg) is calculated as:
Tavg=(H⋅Tc)+((1−H)⋅Tm)
Where:
-
Tc = Cache access time
Tm = Main memory access time
Answer: The memory is called Cache Memory.
