Decoding the Functionality of a Layer 2 Switch- Understanding Its Role in Network Connectivity

What is a Layer 2 Switch?

A Layer 2 switch is a networking device that operates at the data link layer (Layer 2) of the OSI model. It is designed to connect devices within a local area network (LAN) and forward network traffic based on MAC addresses. Unlike Layer 3 switches, which operate at the network layer and can route traffic between different networks, Layer 2 switches focus on managing and optimizing the flow of data within a single network. In this article, we will explore the key features, functions, and benefits of Layer 2 switches in modern network infrastructures.

In the next section, we will delve into the basic functionality of a Layer 2 switch and how it differs from other networking devices.
