Introduction
A switch is a networking device that connects devices within a local area network (LAN) and facilitates communication between them. It primarily operates at Layer 2 (Data Link Layer) of the Open Systems Interconnection (OSI) model, though some switches, known as multilayer switches, can also operate at Layer 3 (Network Layer).
Understanding the fundamental components of switches is essential for managing and securing complex infrastructures, both for exams and in the real world. In this module, we will explore critical concepts such as switches, virtual LANs, and securing networks.
