one-time password — (security) (OTP) A security system that requires a new password every time a user authenticates themselves, thus protecting against an intruder replaying an intercepted password.

The equivalent term "S/Key", developed by Bellcore, is a trademark of Telcordia Technologies, so the name OTP is used increasingly. See RFC 1760 - "The S/KEY One-Time Password System" and RFC 1938 - "A One-Time Password System".
online dictionary — a dictionary that is available on the Internet or World Wide Web and accessed through a Web browser using a computer or a mobile device, primarily by typing a query term into a search box on the site. Online dictionaries like Dictionary.com offer immediate, direct access through large databases to a word's spelling and meanings, plus a host of ancillary information, including its variant spellings, pronunciation, inflected forms, origin, and derived forms, as well as supplementary notes on matters of interest or concern about how the word is used: Some people think online dictionaries will make print dictionaries obsolete.

optical computing — (hardware) (Or "Optical Signal Processing") Operating on data represented using electromagnetic radiation, e.g. visible light, instead of the electrical signals used in a conventional electronic digital computer. Electronic digital computers are built from transistors. These form components that store data and logic gates that perform the low-level Boolean operations such as AND, OR and NOT that are the basis of all digital computation. The optical equivalent requires material with a non-linear refractive index such that light beams can interact with each other to perform the same Boolean operations. Though the photons that carry optical signals offer some theoretical advantages over the electrons that carry electronic signals, there are many practical problems that would have to be overcome before optical computing could compete in terms of cost, power and speed.
