| 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 |
