Glossary

Note: these aren't the definitions you'd find in a book. If that's what you want, then go look in a book. These are they way I would explain the terms to someone. I'd appreciate it if you'd let me know of anything that's misleading or just plain wrong, but I'm not trying to be too strict. Life is tough enough. Sometimes, I may show some sarcasm, though.

VPN

Virtual Private Network. A VPN is created when a company uses the public Internet to connect its sites, and encrypts the traffic so that others cannot understand the contents of packets. A VPN replaces a dedicated (expensive) connection between two locations with a (cheap) internet connection.
