A typical imperative language contains an (1)_ sub language which approximates the mathematical abstractions of" timeless" functions applied to "space- less" values, where the actual operation sequences and use Of storage space duringexpression evaluation are organized behind the (2).In this setting, values are data structures of low volume, typically a few computer words or less, which means that an illusion of (3) can be realized by having intermediatere- suits during expression evalution stored at thediscretion of the language implementation, andeffecting pa- rameter (4)and (5)operations through value copying.(1) A. applicative B. mandatoryC. applicationD. voluntary(2) A. screen B. backgroundC. foregroundD. scenes(3) A. spaceful B. spacelessnessC. spacelessD. space(4) A. transportation B. tranverseC. transmissionD. translation(5) A. assignment B. dispatchC. valueD. design四翻译Query By Example (QBE)In database management programs ,a query technique ,developed by IBM for use in the QBE program ,that prompts you totype the search criteria into a template resembling the data record .The advantage of query-by-example retrieval is that youdon’t need to learn a query language to frame a query .When you start the search ,the program presents a screen that lists allthe data fields that appear on every data record ;enter information that restricts the search to just the specified criteria .Thefields lift bland ,however ,will match anything.Query LanguageIn database management programs ,a retrieval and data-editing language you use to specify what information to retrieve andhow to arrange the retrieved information on-screen or when printing .The dot-prompt language of dBASE is a full-fledgedquery language ,as is Structured Query Language (SQL) ,which is used for minicomputer and mainframe databases and isgrowing in popularity in the world of personal computers .The ideal query language is a natural language ,such as English. ARPAnetA wide area network (WAN) .A network that connected Department of Defense research sites across America. Created in1969 with funding from the Advanced Research Projects Agency (ARPA) .Undergoing constant research and development inthe early-to mid-1970s,ARPAnet served as the test bed for the development of TCP/IP( the protocols that make the Internet possible ).A Major goal of the ARPAnet project was to increase the military's command and control capability by enabling communication across a variety of physically dissimilar media ,including satellites .An allied goal was to create a robustnetwork capable of withstanding outages ,such as those that might result from a nuclear exchange .ARPAnet met these objectives ,but it also surprised its creators :It was found in short order that most ARPAnet users preferred to use the network for communication ,such as electronic mail and discussion groups .Initially ,the ARPAnet was available only to government research institutes and to universities holding Department of Defense (DoD) research contracts .In 1983,ARPAnet was divided into a high-security military network (Milnet )and an ARPAnet that was recast as a research and development network .Although it formed the foundation of the Internet ,it was decommissioned in 1990.。
