On occasion, though, they would throw chad parties for departing sailors in which they would cover their shipmates in chad.
What seems to be jargon may in fact be considered mainstream because it’s been reported that the word chad was used (1993) in the directions for a card-based voting machine in California.

- channel bonding
A technology that combines two telephone lines into a single channel, effectively doubling the data transfer speeds. To take advantage of channel bonding, you need two modems and two telephone lines. If both modems offer 56 Kbps speeds, for example, bonding two modems together would give you a 112 Kbps Internet connection, comparable to an […]
