The document explains network switching, detailing how switched networks consist of interconnected switches that create temporary connections between devices. It outlines the two types of packet-switched networks: datagram and virtual-circuit networks, as well as the characteristics of circuit-switched networks and message-switched data networks. Additionally, it mentions delays in switching techniques.

1. NETWORK SWITCHING

2. A switched network consists of a series of interlinked nodes, called
switches. Switches are devices capable of creating temporary
connections between two or more devices linked to the switch.

3. If the message is going to pass through a packet-switched network, it
needs to be divided into packets of fixed or variable size.
Types of Switching

4. We can have two types of packet-switched networks: datagram
networks and virtual- circuit networks

5. Circuit switched network: A circuit-switched network consists of a set
of switches connected by physical links.

6. Message-switched data networks are hop-by-hop systems that
support two distinct characteristics: store-and forward and
message delivery.

7. Delays in Switching Techniques
