- A JavaBeans component that corresponds to a JSP page that includes JavaServer Faces components. The backing bean defines properties for the components on the page and methods that perform processing for the component. This processing includes event handling, validation, and processing associated with navigation.

The type of items which may be stored in an array - the array's defined type. For instance, in
int[] numbers;
the base type ofnumbersisint. Where the base type is a class type, it indicates the lowest super type of objects that may be stored in the array. For instance, inShip[] berths;
only instances of theShipclass may be stored inberths. If the base type of an array isObject, instances of any class may be stored in it.- Browse Related Terms: array, base type, deep copy, dynamic type, finalization, garbage collection, heterogeneous collection, homogeneous collection, shallow copy, subarray

A search of sorted data, in which the middle position is examined first. Search continues with either the left or the right portion of the data, thus eliminating half the remaining search space. This process is repeated at each step, until either the required item is found, or there is no more data to search.

The smallest unit of information in a computer, with a value of either 0 or 1.
A binary digit, which can take on two possible values:
0and1. Bits are the fundamental building block of both programs and data. Computers regularly move data around in multiples of eight-bit units (bytes for the sake of efficiency).
