The maximum distance an IrDA device can trasmit is 1 meter. The effective range between two IrDA devices is 2 meters.
It is true. The book says "The maximum distance a signal can travel and still be interpreted accurately is equal to a segment's maximum length. Beyond this length, data loss is apt to occur."
The maximum distance a wire can transmit a signal without significant loss in range is typically around 100 meters.
True
The maximum length of a cat 5 e cable with out a repeater is 100meters

what devise makes the computer send long distance messages
The maximum distance of 100BaseT, also known as Fast Ethernet, is 100 meters using twisted-pair cable. Beyond this distance, signal degradation can occur, affecting network performance.
So that it doesn't lose the signal completely before reaching the repeater.
So that it doesn't lose the signal completely before reaching the repeater.
A rangefinder works by using a laser or other technology to measure the distance between the device and a target. The device sends out a signal, which bounces off the target and returns to the rangefinder. By calculating the time it takes for the signal to return, the rangefinder can determine the distance to the target.
higher frequencies attenuate more the further distance they travel.
DME is Distance Measuring Equipment. It is an electronic device located in an aircraft that can measure the distance between that aircraft's location and a point sending out a signal.
