NIMCET 2007 — Computer PYQ

Select the correct memory hierarchy :

Choose the correct answer:

Explanation

Step 1: Understanding Memory Hierarchy

In computer architecture, the memory hierarchy organizes different types of computer storage based on three key parameters:

Speed (Access Time): Faster memory is placed closer to the CPU.
Cost: Faster memory is highly expensive per unit of storage.
Capacity: Due to cost limitations, the fastest storage levels are small, while the slowest are large.

Step 2: Comparing the Given Memory Elements

Let's analyze the access speed and standard hierarchical placement of the components mentioned in the options:

Internal CPU Registers / Cache ( $SRAM$ ): These are the fastest, smallest, and most expensive volatile memory elements located directly inside or closest to the CPU core.
Main Memory ( $DRAM$ ): Dynamic Random Access Memory ( $DRAM$ ) forms the primary workspace system memory (RAM). It is significantly slower than cache but much larger and cheaper.
Read-Only Memory ( $ROM$ ): Non-volatile semiconductor storage used primarily for firmware (like BIOS). In classic system architecture hierarchy layouts, solid-state primary memory systems ( $ROM$ / $RAM$ ) occupy the middle tiers below high-speed CPU caches.
Secondary Storage (Magnetic Disk): Magnetic hard drives or mechanical disks are non-volatile storage components. They have the largest capacities and lowest costs, but their mechanical nature makes them the slowest layer in this group.

Step 3: Determining the Proper Sequence

Arranging these memory types from the fastest (closest to CPU processing) to the slowest (mass storage scale) yields:

$Fastest ⟶ Slowest$

$SRAM (Cache) ⟶ DRAM (RAM) ⟶ ROM ⟶ Magnetic Disk$

Let's look at how the options group these elements sequentially:

Option (c) lists $SRAM$ , $ROM$ , Magnetic disk in a strictly decreasing order of operational performance speed, which precisely matches a top-to-bottom traversal of a standard computer memory pyramid hierarchy.

Final Answer

The correct option is (c) SRAM, ROM, Magnetic disk.
