Question

Explain the role of a switch in the OSI model. How does it differ from a hub?

Expert Solution

Step 1: Introduction

In networking,a switch is a device that operates at the Data Link Layer (Layer 2) of the OSI model. Its primary role is to intelligently forward data frames between devices within a local area network (LAN) based on their MAC addresses.This differs from a hub, which broadcasts data indiscriminately to all connected devices,leading to inefficiencies and security risks.Switches enhance network performance,security,and efficiency by creating separate collision domains,optimizing data transmission,and isolating traffic.
