I submit there are always losses except on a perpetual moving machine which does not exists

yes it is possible
The lossless of an analogous signal is not possible. The two things that will be present all of the time is dispersion, and attenuation.
a frame in computer network, is a digital data transmission unit.
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
it means that you digitize analog data for transmission . Like 2 computer that chatting .
ANALOG:continuous,rate of transmission is slow,less reliable 2 transmit,more noise,interference is more DIGITAL:non continuous,rate of transmission is fast,more reliable 2 transmit,less noise,interference is less
Fiber optic cables transmit digital signals as pulses of light.
This would be called a Data server , or a Host, or database in which you request the files needed and it supplies them to you.

A digital data transmission occurs in a computer bus. The data are in the form of electromagnetic signal, such as an electrical voltage, microwave, radiowave, or infrared signal.
