(in machine building), an accessory for machine tools that serves as an auxiliary support for the workpieces as they rotate during machining. A rest prevents flexing of workpieces because of cutting forces and their own weight and increases their resistance to vibration. Rests are used in machining long flexible shafts and workpieces that have long projections on lathes, circular grinding machines, and thread-milling and spline-milling machines. A distinction is made between steady rests (usually attached to the guide bed) and follow rests (which move together with the saddle).



(Russian pauza,) in music, a break in one, several, or all voices in a musical composition; also, a sign in music notation signifying a break.

In modern music notation, there are whole-note rests, half-rests, quarter-rests, eighth-rests, and 16th-, 32nd-, and 64th-rests. The shorter rests are rarely used. More prolonged rests are usually represented by a long mark with a numeral over it to indicate the number of bars for which the rest is to be observed. Originally, the primary purpose of the rest was to separate melodic voices. Later, the rest was used within melodic lines, and it became an important expressive means.

(1) Rest and relaxation. See digital vacation.

(2) (REpresentational State Transfer) A software architecture for activating services over the Web. Introduced in 2000 by Roy Fielding, one of the authors of HTTP, REST is used to request services and return responses over the Web, commonly known as Web services.

Considered a simpler approach to Web services than the more complex and formal SOAP protocol, "RESTful" Web services make use of standard HTTP verbs, URIs and Internet media types. Requests are made via HTTP, and data is returned in XML, JSON or other data formats. REST concepts predate SOAP but were brought back into focus after developers gained experience with SOAP implementations. See HTTP, URI, Internet media type, WADL and SOAP.
