If they are tunable, yes you can. If the operating frequency is locked, no, you cannot.

External devices are commonly connected using various interfaces, with USB (Universal Serial Bus) being one of the most widely used due to its versatility and ease of use. Other interfaces include HDMI (High-Definition Multimedia Interface) for video and audio devices, Ethernet for networking, and Thunderbolt for high-speed data transfer. Each interface serves specific purposes and supports different types of external devices.

A switch's interface typically refers to the physical ports on the switch through which devices connect, allowing for data transmission within the same local network. In contrast, a VLAN (Virtual Local Area Network) interface is a logical interface associated with a specific VLAN, enabling Layer 3 IP routing and communication between different VLANs. While switch interfaces handle traffic for individual devices, VLAN interfaces manage traffic for groups of devices segmented by VLANs, enhancing network organization and security.
User Interface Devices
To measure the wavelength of radiation from a station, you can use a spectrometer or a diffraction grating. These devices can separate the different wavelengths of light, allowing you to measure the distance between two consecutive peaks. This distance represents the wavelength of the radiation and can be expressed in meters.
Mobile phones communicate with a Bluetooth headset via short-wavelength radio waves. Bluetooth devices can communciate with up to seven different devices at a time.
We can't say the ports are input devices. Ports are just interface to which provides communication medium to the devices.
