Question

Match the following Network devices in List-I with its Functions in List-II.

\[ \begin{array}{|c|l|c|l|} \hline \text{List-I} & & \text{List-II} & \\ \hline (a) & \text{Hub} & (i) & \text{Connects two LAN networks} \\ \hline (b) & \text{Bridge} & (ii) & \text{Connects different networks} \\ \hline (c) & \text{Router} & (iii) & \text{Connects networks using different protocols} \\ \hline (d) & \text{Gateway} & (iv) & \text{Connects multiple devices in a network} \\ \hline \end{array} \]

• A. a-iii, b-iv, c-i, d-ii
• B. a-i, b-iv, c-iii, d-ii
• C. a-iv, b-i, c-ii, d-iii
• D. a-iv, b-ii, c-i, d-iii

Hint:

Important Network Devices:
• Hub → Connects devices
• Bridge → Connects LAN segments
• Router → Connects networks
• Gateway → Connects networks using different protocols

Answer 1

The Correct Option is C

Concept: Network devices are hardware components used to establish communication among computers and networks. Each device performs a specific networking function.

Step 1: Identify the function of a Hub.
A Hub is a simple networking device that connects multiple computers within the same network and broadcasts incoming data to all connected devices. \[ (a) \rightarrow (iv) \]

Step 2: Identify the function of a Bridge.
A Bridge connects two LAN segments and helps reduce unnecessary network traffic. \[ (b) \rightarrow (i) \]

Step 3: Identify the function of a Router.
A Router forwards data packets between different networks and determines the best route for transmission. \[ (c) \rightarrow (ii) \]

Step 4: Identify the function of a Gateway.
A Gateway connects networks that use different communication protocols and acts as a protocol converter. \[ (d) \rightarrow (iii) \]

Step 5: Prepare the final matching.
\[ a-iv,\quad b-i,\quad c-ii,\quad d-iii \] \[ \boxed{a-iv,\; b-i,\; c-ii,\; d-iii} \] Hence, option (C) is correct.
