ADSL- Stands for asymmetric digital subscriber line. An ADSL uses your copper telephone lines and transforms them into a digital line, essentially creating a broadband line. ADSL is slower than its replacement which is fibre optical lines.

AI (Artificial Intelligence) - "AI," or Artificial Intelligence, refers to the simulation of human intelligence in machines and computer systems. It encompasses a range of technologies and techniques that enable computers to perform tasks that typically require human intelligence, such as problem-solving, learning, reasoning, and decision-making.

Analogue Line - Analogue lines are copper cables that transmit a non-digital signal from your premises to the outside world. Traditionally, they provided both data and voice, but now they are typically only used to provide voice due to their low bandwidth capabilities. Analogue data lines were succeeded by ADSL.
