Abstract Type - In software engineering, an abstract type is a type in a nominative type system which is declared by the programmer, and which has the property that it contains no members which also are not members of some declared subtype.

Computer science terms and definitions

In many object-oriented programming languages, abstract types are known as abstract base classes, interfaces, traits, mixins, flavors, or roles. Note that these names refer to different language constructs which are or may be used to implement abstract types.

Canvas provides tools for creating and editing vector graphics and pixel-based images. It is used for illustration, page layout, animation, presentations, and publications in printed and Web formats.

Asynchronous Communications Device Interface - Asynchronous Communications Device Interface ACDI is a software device that permits asynchronous transmission, a way of transmitting data in which one character is sent at a time, and there may be uneven amounts of time between characters.

Computer science terms and definitions

A start bit and a stop bit notify the receiving computer when the transmission begins and ends. In synchronous transmission, strings of multiple characters are transmitted; this method is faster, but more expensive. Acrobat - Acrobat, a document exchange software from Adobe Systems, provides a platform-independent means of creating, viewing, and printing documents.

The Acrobat reader can be downloaded free from the Adobe website. It is most commonly used as a tracking system. In addition, the database stores a set of metatables known as the data dictionary.
