Retail sources, e.g. Rapid Electronics - http://www.rapidonline.com/
and other places that sell RPis.

Or visit http://www.raspberrypi.org/

Its difficult to say more without knowing where you are, so what RPi
sources are near you or what hardware / IT / programming experience you
have.

If you like WiFi, buy the dongle from your favourite store, stuff it in
one of the RPi's USB ports, configure it. I don't use WiFi myself, so
that all I know about it. Pi Zeros (and the Pi 4?) have a built-in WiFi
link.

I use an Ethernet cable to connect the RPi to the nearest Ethernet switch
on my local LAN, so choose which way to go.
