• wireless access points
• VOIP adapters

• streaming audio / internet radio
• network switches (some with POE)
• multi function scan / copy / email /print devices
• NAS (Network Attached Storage) devices

• IP telephones

All such devices are interconnected usually with Cat5e or Cat6 data cabling.
