Question | Answer |
What is Pervasive Computing + Environments | embedding microprocessors in everyday objects so they can communicate information--
Devices, Networking, middleware, and applications |
Pervasive Devices | Traditional devices - Keyboard, Mice.//
Wireless Mobile Devices - Pagers, Cellphones.//
Smart devices - intelligent applications, floor tiles with embedded sensors |
Pervasive Networking | Links devices together, "Backbone of the network" |
Pervasive Middleware | Software that enables two seperate programs to work with eachother.
Can act as a communicator between two softwares/networks |
Pervasive Applications | Help guide middleware and networking issues |
Advantages of using graphs and charts | Save time, Gain attention, Show relationships, Permit study of data Efficient use of information |
Graph uses: Efficient use of information | Represent verbal descriptions, helps to make understanding information easier |
What is a chart? | Portrays structure of a set of data. Shows the parts in some relationship to the whole. Depicts a sequence of events |
Line Graphs | At least one data path to portray changes in a continuous variable |
Bar charts | Compare the values of one or more variables. Compare geographic areas. Compare components of a larger unit. |
Advantages to Bar charts | Flexibility and visual impact |
Pie Chart | Represented by slices. |
Advantages of pie charts | Visually appealing and can show precentages |
GIS- Geographical Information Systems | A geographic information system designed to capture store, manipulate, analyze, manage and present all types of geographical data |
Geo Information Science | The science underlying geographic concepts, applications, and systems |
Famous Definition of a program | Programs equal Data Structures plus algorithms |
Algorithm | A set of necessary steps to accomplish a particular task |
Input | Data being used by an algorithm |
Process | A way that the data can be manipulated |
Output | The result of applying the processes to the input |
What makes semantic web possible? | XML, RDF, Ontologies, Logic |
XML | Extensible Markup Language- a markup language that both machines and humans can read |
RDF | Resource Description Framework- Language capable of describing all sorts of information and metadata |
Ontologies | Ontologies- Language used to define vocabularies and establish the usage of words and terms |
Logic | Logical Reasoning- Used to establish the consistency and correctness of data sets and to infer conclusions that aren't explicitly stated |
Pervasive Computing definition | A term that signifies several new elements of computing |
Elements of Pervasive Computing | Computers and sensors everywhere in devices and a high degree of communication among devices |
What is a semantic web? | make data located anywhere in the Web accessible and understandable to people AND machines |
