What is the definition of a network according to the learning material?

• A method of selecting paths along which packets are sent on a computer network.

• A collection of computers, servers and other network devices connected to allow sharing of resources and data.

• A formatted unit of data that is transmitted over a packet-switching network.

• Methods for connecting devices to each other in order to transfer data, including cabling and wireless.

Which protocol is responsible for addressing and routing of data on the Internet?

• Transmission Control Protocol (TCP)
