Electrical terminators are installed at the end of a bus or transmission line to prevent signals from reflecting back.

Waveguide terminators absorb energy and prevent RF signals from reflecting back from open-ended or unused waveguide ports

RF terminators are used to absorb energy and prevent RF signals from reflecting back from open-ended or unused ports

Coaxial terminators are electrical devices that connect to the ends of coaxial cables to prevent signals from reflecting back when they reach the end of the cable

RF adapters are used to connect different waveguides and/or coaxial types.

SCSI terminators are electrical circuits placed at each end of a SCSI cable for impedance matching.

Coaxial connectors are composed of an insulated central conducting wire wrapped in another cylindrical conductor (the shield).
