Question

Consider the following computer memory devices and arrange these from slowest access time to device with the fastest access time A. Main Memory
B. Secondary Memory
C. Registers
D. L2 cache
E. L1 cache Choose the correct answer from the options given below

• A. \(A\rightarrow B\rightarrow E\rightarrow C\rightarrow D\)
• B. \(B\rightarrow A\rightarrow E\rightarrow D\rightarrow C\)
• C. \(B\rightarrow A\rightarrow D\rightarrow E\rightarrow C\)
• D. \(C\rightarrow E\rightarrow D\rightarrow A\rightarrow B\)

Hint:

Registers are fastest while secondary memory is slowest.

Answer 1

The Correct Option is C

Concept:
Memory hierarchy is arranged according to access speed.
Step 1:
Secondary memory (hard disk/SSD) is slowest. \[ B \]
Step 2:
Main memory is faster than secondary memory. L2 cache is faster than RAM. L1 cache is faster than L2 cache.
Step 3:
Registers are fastest memory units. \[ C \]
Step 4:
\[ B\rightarrow A\rightarrow D\rightarrow E\rightarrow C \] \[ \boxed{\text{Correct Option = (3)}} \]
