What is packet switching (part of the design of the Internet)? How does the following work with
packet-switching: client, server, router? - correct answer ✔✔Packet-switched network - Takes
bundles of data and breaks them up into small packets or chunks that travel through the
network independently.
Client: The bits of data that make up an email message, Web page, or image, ow through
interconnected computers from their points of origin to the destination. The sender's computer
is the origination point, known as the client.
Server: The message bits leave the client computer and travel in separate packets to a server. A
server is basically a powerful computer that provides continuous access to the Internet.
Router: From there, packets move through routers. A router is a computer that links smaller
networks and sorts each packet of data until the entire message is reassembled, and then it
transmits the electronic packets either to other routers or directly to the addressee's server. The
server holds the entire message until an individual directs his or her client computer to pick it
up.
