In programming, a series of objects all of which are the same size and type. Each object in an array is called an array element. For example, you could have an array of integers or an array of characters or an array of anything that has a defined data type. The important characteristics of an array are:
Each element has the same data type (although they may have different values).
The entire array is stored contiguously in memory (that is, there are no gaps between elements).
Arrays can have more than one dimension. A one-dimensional array is called a vector ; a two-dimensional array is called a matrix.
- array processor
Also called a vector processor. A microprocessor that executes one instruction at a time but on an array or table of data at the same time rather than on single data elements.
- arrow keys
Most computer keyboards contain four arrow keys for moving the cursor or insertion point right, left, up, or down. When combined with the Shift, Function, Control, or Alt keys (on PCs), the arrow keys can have different meanings. For example, pressing Shift +Up-arrow might move the cursor or pointer up an entire page. On Macintoshes, […]
- Artificial Intelligence (AI)
Artificial intelligence is the branch of computer science concerned with making computers behave like humans. The term was coined in 1956 by John McCarthy at the Massachusetts Institute of Technology. AI Specialization Artificial intelligence includes the following areas of specialization: games playing: programming computers to play games against human opponents expert systems: programming computers to […]
In typography, the portion of a lowercase letter that rises above the main body of the letter (that is, above the height of a lowercase x). For example, the letter t’s ascender is the part of the vertical line above the horizontal line.
- aspect-oriented programming
Aspect-oriented programming, or AOP, complements object-oriented programming by allowing the developer to dynamically modify the static object-oriented model to create a system that can grow to meet new requirements, allowing an application to adopt new characteristics as it develops. *AOP provides a solution for abstracting cross-cutting code that spans object hierarchies without functional relevance to […]
