I spent a good 20 minutes the other day, trying to make an antenna fit a Wireless LAN (WLAN) card. It just wouldn't snap on, and finally, I realized the antenna had a U.FL plug, whereas the WLAN card had a MHF 4 socket : )
I'd never heard of MHF 4 before, but it seems to be very popular in the laptop computer world. Anyway, while I was at it trying to visually compare the connectors, I took this photo - perhaps useful for identifying connectors in the future : )
The photo is missing connectors, especially some common ones like N connector, and the PL-259 (popular in ham radio equipment).
BNC of course is very popular, as is SMA. I really like SMB, it's like a hassle-free version of SMA, but unfortunately, it is not as popular on equipment.

EDIT:
Decided to re-take the photo and add N and TNC. Also added a PL-259.
