What are network transmission devices explain any two of them?

Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves. Connectors are used to connect the media with networking devices, and they are specific for each transmission medium.

Computer networks share common devices, functions, and features including servers, clients, transmission media, shared data, shared printers and other hardware and software resources, network interface card(NIC), local operating system(LOS), and the network operating system (NOS).

How network devices are connected?

Definition: A connectivity device to which network cables are attached to form a network segment. Hubs typically do not filter data, but instead retransmit incoming data packets or frames to all parts. Almost all networks today use a central hub or switch to which the computers on the network connect.
