Answer:
Transmission speeds differ widely among media
Explanation:
Lots of different transmission media use transmit at different speeds via different transmission channels or path..
Transmission speed should be seen as the rate which data are transmitted or sent from one transmission point to another across a communications channel.
The standard measurements of transmission is "Bits per second”.
The fastest transmission media is the optical fibre due to its efficiency, ability to assist the long distance communication and speedy transfer rate.
