Networking Devices and Topologies

1.2. Use

Switches are used to build the internal structure of most wired networks, connecting computers, printers, servers, and other switches to create a seamless local network.

Switches are critical network devices operating at the Data Link Layer (Layer 2 of the OSI model), responsible for forwarding data frames within a local area network (LAN) based on MAC addresses. They come in two primary types: unmanaged and managed switches, each designed for different use cases, offering distinct levels of control, functionality, and complexity. Below is a detailed exploration of these switch types, their features, use cases, advantages, and disadvantages.

1. Unmanaged Switches

Unmanaged switches are basic, plug-and-play devices that require no configuration. They are designed to automatically handle data forwarding within a network, making them simple to deploy and use.
