Short for Wi-Fi Protected Access, a Wi-Fi standard that was designed to improve upon the security features of WEP. The technology is designed to work with existing Wi-Fi products that have been enabled with WEP (i.e., as a software upgrade to existing hardware), but the technology includes two improvements over WEP:
machine bolt (a bolt with a square or hexagonal head on one end and a threaded shaft on the other end; tightened with a wrench; used to connect metal parts). kingbolt; kingpin; swivel pin (bolt that provides a steering joint in a motor vehicle).
The definition of a shaft is a long, narrow handle or a long narrow part of something, a sudden bolt of light or a sudden flash of some feeling. The long narrow handle of a golf club is an example of a shaft. A long narrow mine shaft or a vertical elevator shaft are both examples of a shaft. A sudden bolt of lightening is an example of a shaft of lightening. A sudden flash of happiness is an example of a shaft of happiness.
