Help through the tech thicket for journalists
The Hack/Hackers group, which is designed to help journalists connect with and understand the technology running their lives, has a very useful glossary of tech terms.
I suggest reading it - two or three times. You don't have to get all tech-talk about things, but these days you do have to understand what the tech talk is all about.
Another version of the glossary with a little more commentary is on Poynter.
Hack/Hackers was put together by three journalists: Rich Gordon of Northwestern, Aron Pilhofer of the New York Times and former AP correspondent Burt Herman.
