The Internet is an example of a Packet switched network
Packet-switched describes the type of network in which relatively small units of data called packets are routed through a network based on the destination address contained within each packet. Breaking communication down into packets allows the same data path to be shared among many users in the network.
The best-known use of packet switching is the Internet and most local area networks. The Internet is implemented by the Internet Protocol Suite using a variety of Link Layer technologies. For example, Ethernet and Frame Relay are common.
Packet switching is a philosophy of network communication, not a specific protocol. The protocol used by the Internet is called TCP/IP. ... The IP in TCP/IP stands for Internet protocol and is the protocol used by computers to communicate with each other on the Internet. Computers using the Internet must have IP software.
A packet switched network (PSN) is a type of computer communications network that groups and sends data in the form of small packets. It enables the sending of data or network packets between a source and destination node over a network channel that is shared between multiple users and/or applications.
