Which of the following statements are true in the context of the memory hierarchy?

1.Memories are made up of registers

2.Memory locations are identified using an address

3.The total number of bits a memory can store is its capacity

4.A storage element is called a cell

5.Data in a memory are stored and retrieved by the processes called writing and reading respectively

A1, 2, 3 and 4

B2, 3 and 4

C1, 2, 3, 4 and 5 ✓ Correct

D1, 2 and 4

Correct answer: (C) 1, 2, 3, 4 and 5

Explanation

All five statements about memory correctly describe how it is built and used.

Statement 1 is right, since memories are built from registers of storage cells.

Statement 2 is right, since each location is identified by a unique address.

Statement 3 is right, since the total bits a memory holds define its capacity.

Statement 4 is right, since a single storage element is called a cell.

Statement 5 is right, since storing is writing and retrieving is reading.

Address lines select a cell while data lines carry its contents.
