Answer:
The telegraph and the telephone affected the communications because they made instantaneous long distance communication possible.
Step-by-step explanation:
Every time we talk about the great revolution associated with data transmission and the principles of information security was triggered by the Internet, it is vital to take into account the following: there were previous revolutions, which were comparable to the Internet in terms of magnitude. There are those who in this context refer to the written press, while others refer to the radio or TV.
However, it would be far more fair to give the telegraph and telephone the place they deserve. Because they were the first technologies that allowed the transmission of data instantly, while the electric telegraph was the first to employ electrical signals for such purposes.
Today may seem strange, but the ability to speed up the transmission of data radically was not appreciated immediately. Telegraph and telephone companies had to invest a lot of time and effort in order to prove the true value of this technology.
