COPY: Computer Networking Basics

Computer networks only use wired connections for interconnections.

Hostnames are frequently changed after initial assignment in computer networks.

Computer networks do not support access to the World Wide Web.

Networking hardware is not considered a node in a computer network.

Computer networks may be classified by the transmission medium used to carry signals.

Protocol Data Unit (PDU) in the context of packet switching data networks is best understood in relation to a service data unit (SDU)

Transmission Control Protocol (TCP) uses datagrams as the protocol data units for connectionless communication

The PDU at the Internet layer in the Internet protocol suite is called a segment

The physical layer sends ones and zeros across a wire or fiber in a computer network

The transport layer delivers the data to the right software application at the destination in a computer network
