• Object
• is a combination of data (called data members) and the operations (called methods) that can be performed on or with that data

Constructors …..to create the object

Mutator methods: to assign/change data members

Accessor methods: to return data members

Methods used within the object (another method calls the method);

Methods unique for that set of data

programming approach in which units of data are viewed as active “objects” instead of the passive units from procedural paradigm

devices and software used to “read” characters and translate into ASCII characters for later processing.

Ex: scanning printed documents to convert text into digital ASCII text that can be edited

optical mark and read forms

when user has access to a computer via a terminal

• processing in which all operations are performed by equipment directly under the control a central processor.
• Ex: airline reservations.

software that controls the execution of programs and that may provide services such as resource allocation, scheduling, input/output control and data management.

Ex: 3 + 4 * 5 = 23, because of operator precedence; multiplication first, then addition
