Hello. I am looking at getting a new wireless card for my Dell Latitude E6520 running Ubuntu 16.04 LTS. I want to know what the difference between a/b/g/n is. Can anyone please help? Thanks.

:)

I'd suggest the readings above, but if you want the tldr:

Basically, each iteration improves thoroughput speeds (data transfer) and usually has some range improvements as well. In this day and age, B is pretty terrible to be stuck on, so I'd suggest going for N as it will match with most modern peripherals; if you want cutting edge, AC with Mu-MIMO is recommended.
