Computer Science Terms Essay -- Definitions

Computer Science TermsComposite structure the size of a typical software strategy implies that it must be broken down into manageable servicemans of thisComposition the operation of building a arranging using simpler parts or componentsAbstraction the process of ignoring details digressive to the problem at hand and emphasizing essential ones. To abstract is to disregard certain differentiating detailsData the info the computer programme deals withFunctionality what the program does with the data, the responsibility of the bearing to doObject the most abstract description of a basic component of an object oriented systemValues a profound piece of info that can be manipulated by the programTypes a set of related values along with the operations that can be preformed with themObject fundamental abstractions from which systems are builtClasses a set of objects having the same features and propertiesState of an object the set of data maintained by an object at any abandoned time Reference values a value that denotes an objectData descriptions properties of the object (name, date, etc)Associated value a property an object has at any condition timeVariable a portion of memory reserved to hold a single valueInstance changeables a variable that is a unchangeable part of an object memory space for the variable is allocated when the object is createdImmutable an object thats accede cannot be changedMutable and object thats state can be changed*An object is characterized by the features it offers*1. Query a request for data2. Command a request to change stateFloat & figure sets of real quick-scented numbers (i.e. 170000 or 1.4e12)Char set of values representing Unicode ... ...Chapter 6*Black knock testing = functional testingTest propose generally begins with an analytic thinking of The functional specifications of the system The ways in which the system will be usedTest sideslip is defined by A statement of case objectives The data set for the case The expected resultsFunctional testing testing to determine that the system as a whole meets the customers specifications. The system is treated as a black box whose behavior can be observed, but whose internal structure is unknown.*white box testing= whole testing social unit testing incremental testing of classes as they are implemented in order to ensure that they function properly. Testing can be white box testing where the tests are developed based on the units implementation, or gray box testing where tests are developed based whole on a methods specification Computer Science Terms Essay -- DefinitionsComputer Science TermsComposite structure the size of a typical software system implies that it must be broken down into manageable pieces of thisComposition the process of building a system using simpler parts or componentsAbstraction the process of ignoring details irrelevant to the problem at hand and emphasizing essential ones.
