You are probably already acquainted with analogue telephone lines, as you are likely to have one in your home. Analogue technology is used by millions of people on a daily basis.
The technology behind the analogue line turns your voice (or any other audio signal) into a series of electronic pulses. This is different from the modern digital technology, which represents the signals in a different way. Basic lines are ideal for fax lines, home offices and are required for the underlying connection for Broadband services.
Analogue has been around for a long time and due to its simplicity is usually a much cheaper option than digital, but it cannot carry huge quantities of data.
