V.23: The CCITT modulation standard for 75/1200 bps, half-duplex transmission over dial-up lines. This is not common in North America.

V.24: The CCITT hardware interface specification for interchange circuits between the DTE and DCE.

WATS (Wide Area Telephone Service) (pronounced "watts"): A discounted long-distance calling plan that allows calls in or out. The popular 800 numbers are WATS lines in. The calls are charged to the holder of the 800 number at a discounted rate.

Workstation: Traditionally a workstation has been a dumb terminal connected to a host. With the advent of LANs and WANs, PCs that are connected to a LAN are now called workstations also, even though they are capable of independent processing. A workstation, then, is simply an input/display device through which a user accesses a resource.
