Last updated: October 31, 2007 «I'm sitting in a coffee shop in Milford, NH. In the booth next to me are two men, a father and a son. Over coffee, the father is asking his son about modems, and the son is holding forth pretty well on the subject of compatibility, UART requirements, and so on. But he's little out of date: The father asks, "So should I get one with a DSP?"

"A what?" says the son.

You just can't get far if you're not up on the lingo. You might squeak by in your company of technological nonexperts, but even some of them will surprise you. These days, technical acronyms quickly insinuate themselves into the vernacular.»
