What is a type of local network that people can use to access the Internet?

Computer

Mobile

Public Wi-Fi

Router

Router: it can host the local network at home (via wifi) and through NAT (network area translation), route local traffic to internet traffic

Id say Router is the answer based on your Question.

Router - is a device used to host a network signal which people will require the SSID (network-name) to connect to.

It is a bit confusing because the correct answer is SSID which leads me to belive Public Wi-Fi is also correct ...
