Wired Ethernet is basically

ISDN is a wired, all-digital line technology, the choice this item matches with wired Ethernet.

ADSL is a broadband technology carried over ordinary copper telephone lines, with faster download than upload.

Broadband is a general term for high-capacity always-on internet access, not a single specific line type.

The internet is the global network of networks itself, not a kind of wiring like Ethernet.

Ethernet and ISDN both run over physical wires rather than radio.

ISDN carries voice and data together as integrated digital services.
