Detailed explanation-1: -A network switch connects devices in a network to each other, enabling them to talk by exchanging data packets. Switches can be hardware devices that manage physical networks or software-based virtual devices. A network switch operates on the data-link layer, or Layer 2, of the Open Systems Interconnection (OSI) model.
Detailed explanation-2: -There are three distinct functions of layer 2 switching (you need to remember these!): address learning, forward/filter decisions, and loop avoidance.
Detailed explanation-3: -A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). Switches are incapable of joining multiple networks or sharing an Internet connection.
