Cards in this set: Term Analog Definition Real World Representation of Data Information represented in continuous form Term Digitial Definition Information represented in discreet form. I.E. Breaking infomration in to separate elements. Term Von Neuman Architecture Definition A computer architecture in which data and instructions to manipulate the data are logically the smae and camne be stored in the same place. Term Fetch-Execute Cycle Definition Fetch Decode Gather Execute Term Piping Definition Programs can be run together such that one program reads the output from another with no need for an explicit intermediate file Term Port Definition numerical designation that corresponds to a particular high level protocol. Port numbers are used to help control and process network traffic.

Term Subclass Definition a class with inherited properties of the superclass Term Tcp/ip Definition suite of protocols and programs that support low-level network communication(TCP rests on top of IP foundation) Term Traceroute Definition A program that shows the route a packet takes across the internet Term Turing test Definition proposal for a test that tests a machine’s capability to perform human-like conversation Term Turing machine Definition a machine that performs human-like conversation Term Whois Definition queries a database in order to determine information about the owner of a domain name, ip address or system Term OS Definition core of the system software that manages computer resources and provides an interface for system interaction Term Data type Definition description of the set of values and the basic set of operations that can be applied to values of the type. Term Control structure Definition an instruction that determines the order in which other instructions in the program are executed. Term Data structure Definition The implementation of a composite data field in an abstract data type Term Abstract data structure Definition a data type whose properties are specified independently of any particular implementation Term Abstraction Definition a model of a complex system that includes only the details essential to the viewer. Term Compiler Definition a program that translates a high level programming language to machine language Term Interpreter Definition immediately translates prog language to machine language and executes. Term Boolean expression Definition a sequence of identifiers separated by compatible operators that evaluate to true or false Term Machine language Definition the language made up of binary-coded instructions that is used directly by the computer Term Inheritance Definition a mechanism by which one class acquires the properties, data fields, and methods of another class. Term Polymorphism Definition ability of the language to have duplicate method names in an inheritance hierarchy and to apply the method that is appropriate for the object to which the method is applied. Term Encapsulation Definition the bundling of data and actions in such a way that the logical properties of the data and actions are separated from the implementation details.

Pg. 72 Term Run Length encoding Definition “recurrence coding” ex. AAAAAAAA would become A8. Replaces a long series of repeated character with a count of the repetition Term Codec Definition Methods used to encode something in order to reduce the size.
