HUB
An Electronic Device
modem is the device that carries digital signals
yes it is...you have to put electricity into it to get light out of it
There are two kinds of telemetry--one-way, where the remote device sends instrumentation signals to the receiving station; and two-way, where the receiving station can send control signals back to the remote device. The range is literally unlimited--deep-space probes have two-way telemetry gear on them, and it can take months or even years to transmit a message from the vehicle to the earth.
An electrical annunciator is a device that provides visual or audible alerts for various conditions or events within a system. It is commonly used in industrial and commercial settings to notify operators of alarms, warnings, or status changes in equipment or processes.
Yes, enabling "Do Not Disturb" mode on your device typically does not affect alarms. Alarms are usually designed to override this mode, ensuring that they will still sound at the scheduled time. However, it's always a good practice to test your specific device settings to confirm that alarms function as expected when "Do Not Disturb" is activated.
DSLAM
An oscilloscope is a device that magnifies changes in electrical signals, displaying them as a graph on a screen. It is commonly used in electronics to visualize and analyze electronic signals.
No, it is an output device. It outputs sound waves.
Bluetooth is a device that used to transmit data from one station to another station or device
In the centralized method of enforcing transmission control, a central controller or station manages access to the communication medium by determining which device can transmit at any given time. This approach helps prevent collisions by ensuring that only one device is allowed to send data while others remain silent. The central controller can prioritize transmissions based on various criteria, ensuring efficient and orderly communication among the devices. However, this method relies heavily on the central station's reliability and introduces a single point of failure in the system.
