Overview

Switches are essential components in electrical and networking systems, used to control the flow of electricity or data between devices. In networking, they connect multiple devices on a local area network (LAN) and manage data traffic to ensure efficient communication. They come in various types, including managed and unmanaged switches, and are crucial for maintaining robust and scalable network infrastructure.
