The correct answer is ADSL.
ADSL (Asymmetric Digital Subscriber Line) is a type of DSL technology that enables faster data transmission over copper telephone lines than traditional modems. ADSL is asymmetric because it provides faster downstream (from the internet to the user) speeds than upstream (from the user to the internet) speeds. This is because most internet users download more data than they upload, so ADSL is designed to prioritize downstream speeds.
Routers are devices that connect multiple devices to a computer network. They route data packets between different networks, such as the internet and a local area network (LAN).
VDU (Visual Display Unit) is a
generic term for a computer monitor. It is a display device that shows the output of a computer.LAN (Local Area Network) is a group of computers and other devices that are connected together so that they can share resources, such as files, printers, and internet access.
ADSL is the best option for providing high speed internet access over traditional modem lines because it is faster than traditional modems and it is more reliable.
