Match the network device/function to its layer in the OSI model.Group of answer choicesRouterSwitchMAC AddressIP AddressFrame

To match the network device/function to its layer in the OSI model, we first need to understand the OSI model's layers and the corresponding network devices or functions that operate at those layers.

OSI Model Layers Overview

1. Layer 1 - Physical Layer: Deals with the physical connection between devices (cables, switches).
2. Layer 2 - Data Link Layer: Manages node-to-node data transfer and handles error correction from the physical layer (switches, MAC addresses).
3. Layer 3 - Network Layer: Responsible for data routing, forwarding, and addressing (routers, IP addresses).
4. Layer 4 - Transport Layer: Provides reliable data transfer services to the upper layers (not applicable in this question).

Matching

1. Router - Layer 3 (Network Layer): Routers operate at the network layer and are responsible for directing data packets across networks.

2. Switch - Layer 2 (Data Link Layer): Switches operate at the data link layer, managing the data flow within a local area network (LAN).

3. MAC Address - Layer 2 (Data Link Layer): MAC (Media Access Control) addresses are used to identify devices on the same local network and function at the data link layer.

4. IP Address - Layer 3 (Network Layer): IP (Internet Protocol) addresses are used for identifying hosts and routing packets over the network.

Summary of Matches

• Router: Layer 3
• Switch: Layer 2
• MAC Address: Layer 2
• IP Address: Layer 3

This analysis reveals the relationship of various network devices and functions concerning their respective layers in the OSI model.
