Question

Match List-I with List-II: 

List-I (Topology)	List-II (Characteristics)
(A) Star	(I) Single backbone cable
(B) Bus	(II) Central hub or switch
(C) Ring	(III) Unidirectional link
(D) Hybrid	(IV) Multiple branches

Choose the correct answer from the options given below: 

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (II), (B) - (I), (C) - (III), (D) - (IV)

Hint:

Keywords:
Star \(\rightarrow\) Central hub/switch.
Bus \(\rightarrow\) Single backbone cable.
Ring \(\rightarrow\) Token Unidirectional loop.
Hybrid \(\rightarrow\) Combination Multiple branches.

Answer 1

The Correct Option is D

Concept:
Network topology describes the physical or logical arrangement of nodes, devices, and connecting links within a computer network.

Step 1: Matching Topologies to Characteristics:
- (A) Star Topology: All nodes are individually connected to a central connecting device, such as a hub or switch. Thus, (A) corresponds to (II).
- (B) Bus Topology: Devices connect to a single central shared transmission line called a backbone cable. Thus, (B) corresponds to (I).
- (C) Ring Topology: Each node connects to exactly two neighboring nodes, forming a continuous circular loop where data typically travels in a single, unidirectional link. Thus, (C) corresponds to (III).
- (D) Hybrid Topology: Combines two or more different topologies (e.g., star-bus or star-ring), resulting in multiple hierarchical branches. Thus, (D) corresponds to (IV).

Step 2: Identifying the Correct Code Sequence:
The matching pairs are: \[ \text{(A)-(II), (B)-(I), (C)-(III), (D)-(IV)} \] Final Answer:
This matches option (D).
