(B). Cache Memory 
(C). Random Access Memory (RAM) 
(D). Registers Arrange the above memories according to their access speed (from fastest to slowest) 
1. (D), (C), (B), (A)

Solution

We need to arrange memories from fastest to slowest in terms of access speed:

  • Registers (D): Fastest (located inside CPU).

  • Cache Memory (B): Next fastest (very close to CPU, faster than RAM).

  • RAM (C): Slower than cache.

  • Hard Disk Drive (A): Slowest (secondary storage).

So the correct order is:

Solution

Per unit cost comparison (lowest → highest):

  • (E) Magnetic tape → Cheapest (backup/archive storage)
  • (B) Magnetic disk → Hard disk, inexpensive
  • (C) Optical disk → CD/DVD/Blu-ray, costlier than HDD
  • (A) DRAM → Main memory, more expensive
  • (D) SRAM → Cache memory, fastest and most expensive

Final Order (increasing per unit cost):

E < B < C < A < D

Solution

Solution:

List - I List - II Match
(A) Flash Memory (IV) Non-volatile RAM which is powered continuously A → IV
(B) PMOS (I) Oldest and slowest B → I
(C) NMOS (II) Used in large scale integration (LSI) C → II
(D) CMOS (III) Least power consumption D → III

Final Answer: (A) → (IV), (B) → (I), (C) → (II), (D) → (III)
