if a friend asked you to help her decide what internal sabling system to install in her new house, what kinds of questions wouls you ask her to do? why would you ask those questions?

Assuming you mean *cabling system*

you could ask:

- The architectural structure of the building, which houses for the cabling installation.

- The function of the cabling installation.

- The configuration of an already installed system (upgrades and retrofits).

others

- The cable and connection products.

- The types of equipment the cabling installation will support -- present and future.

- Customer requirement.

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
