The trade routes of the classical era most resemble the Internet because they both?
Originate from a central capital of a specific civillization. Is the correct answer.
Why were early radios called wireless?
Up until the invention of radio, communication had to be sent long distances along wires and cables. i.e. telegraph or telephone. With the invention of radio, communication was not restricted to the use of wires. Hence wireless is two words 'wire' and 'less' meaning without wire.
The frequency of a light wave with wavelength 0.005 meters is Hz?
Frequency = speed/wavelength = (300,000,000)/(0.005) = 60 GHz.This is not light. This is microwave radio communication over relatively short distances.
What inventions came about because of radio?
the telegraph and the telephone, came from the radio all three technologies are closely related, because they use "wireless telegraphy" There are probably many more just look up all the inventions of Nikola Tesla. He has over 50 Patton's in the US and Canada alone +++ And the Television and Radar! Both are particular types, or rather applications, of radio.
How do long wavelength radio waves communicate over big distances?
aids

What are the similarities between telecommunication and ict?
Data communication is the communication using any type of data like Electronic communication like TV, radio, Video, audio, email, messaging over the internet and telecommunication and everything else.Telecommunication is a subset of data communications. Telecommunications is a general term for a vast array of technologies that send information over distances. Mobile phones, land lines, satellite phones and voice over Internet protocol (VoIP) are all telephony technologies -- just one field of telecommunications. Radio, television and networks are a few more examples of telecommunication.
