You know, I just realized how long it's been since I recorded a PodSnack myself. The guys at the office gave me so many of them, I've been posting theirs for a couple of weeks now. I finally decided it's time for me to step up to the plate again. Since we've been talking about various Internet-related concepts, and since this question came up in my class last week, I thought I'd tackle the term Internet service provider (ISP). Most of us probably know what this is and, if we don't, the term is pretty self descriptive. But we also talk about ISPs in various tiers (e.g., Tier 1, Tier 2, Tier 3). This is somewhat confusing to people these days, so I'll focus on it a bit in today's PodSnack.
