Depending on whether it is a physical medium (cable) or a wave-based communication (wireless), mainly the following networking mediums for data transferring and communication are used:

• Metallic mediums, copper wires in twisted pairs and coaxial cables transmit electrical impulses
• Glass mediums, fibre optic cable transmit pulses of light
• Air mediums, waves and rays from the electromagnetic spectrum transmit signals in different frequencies
