How do I keep my computer and data safe and secure while using the Internet?

Some things that I use is a VPN...

Also make sure not to overshare information on social media...

Oh and don't use the same password for everything (I'm guilty of this one lol)

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.
