Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communications facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). Telnet was developed in 1969 beginning with RFC 15, extended in RFC 854, and standardized as Internet Engineering Task Force (IETF) Internet Standard STD 8, one of the first Internet standards. Historically, Telnet provided access to a command-line interface (usually, of an operating system) on a remote host. Most network equipment and operating systems with a TCP/IP stack support a Telnet service for remote configuration (including systems based on Windows NT). Because of security issues with Telnet, its use for this purpose has waned in favor of SSH. (Excerpt from Wikipedia article: Telnet)

xml schema

An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints.

data model

A data model in software engineering is an abstract model, that documents and organizes the business data for communication between team members and is used as a plan for developing applications, specifically how data is stored and accessed. A data model explicitly determines the structure of data or structured data. Typical applications of data models include database models, design of information systems, and enabling exchange of data. Usually data models are specified in a data modeling language. (Excerpt from Wikipedia article: Data model)

Freedom of information (or information freedom) refers to the protection of the right to freedom of expression with regards to the Internet and information technology (see also, digital rights). Freedom of information may also concern censorship in an information technology context, i.e. the ability to access Web content, without censorship or restrictions. Freedom of information is an extension of freedom of speech, a fundamental human right recognised in international law, which is today understood more generally as freedom of expression in any medium, be it orally, in writing, print, through the Internet or through art forms. This means that the protection of freedom of speech as a right includes not only the content, but also the means of expression. Freedom of information may also refer to the right to privacy in the context of the Internet and information technology. As with the right to freedom of expression, the right to privacy is a recognised human right and freedom of information acts as an extension to this right.

SOAP, originally defined as Simple Object Access Protocol, is a protocol specification for exchanging structured information in the implementation of Web Services in computer networks. It relies on Extensible Markup Language (XML) for its message format, and usually relies on other Application Layer protocols, most notably Remote Procedure Call (RPC) and Hypertext Transfer Protocol (HTTP), for message negotiation and transmission. SOAP can form the foundation layer of a web services protocol stack, providing a basic messaging framework upon which web services can be built. This XML based protocol consists of three parts: an envelope, which defines what is in the message and how to process it, a set of encoding rules for expressing instances of application-defined datatypes, and a convention for representing procedure calls and responses. (Excerpt from Wikipedia article: SOAP)

mobile phone

A mobile phone (also called mobile, cellular telephone, cell phone, or hand phone (in Southeast Asian English)) is an electronic device used to make mobile telephone calls across a wide geographic area. Mobile phones are different from cordless telephones, which only offer telephone service within a limited range of a fixed land line, for example within a home or an office. A mobile phone can make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed-line phones across the world. It does this by connecting to a cellular network owned by a mobile network operator. In addition to functioning as a telephone, a modern mobile phone typically supports additional services such as SMS (or text) messaging, MMS, e-mail and Internet access; short-range wireless (infrared or Bluetooth) communications; as well as business and gaming applications, and photography. Mobile phones that offer advanced computing abilities are referred to as smartphones. (Excerpt from Wikipedia article: Mobile phone)

In general, a namespace is a container that provides context for the identifiers (names, or technical terms, or words) it holds, what allows the disambiguation of homonym identifiers residing in different namespaces. For many programming languages, a namespace is a context for their identifiers. In an operating system, an example of namespace is a directory. Each name in a directory uniquely identifies one file or subdirectory, but one file may have the same name multiple times. (Excerpt from Wikipedia article: Namespace)

The Research Support Libraries Programme (RSLP) was a national initiative, funded by the four higher education funding bodies. It has brought together both traditional and new forms of access to library information, with specific reference to support for research. While the principal beneficiaries of the Programme have been researchers and their postgraduate research students in UK higher education institutions (HEIs), there have also been significant benefits for other groups. It started in the academic year 1999-2000 and finished on 31 July 2002. (Excerpt from this source)

google scholar

Google Scholar is a freely accessible web search engine that indexes the full text of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes most peer-reviewed online journals of Europe and America's largest scholarly publishers. It is similar in function to the freely-available Scirus from Elsevier, CiteSeerX, and getCITED. It is also similar to the subscription-based tools, Elsevier's Scopus and Thomson ISI's Web of Science. Its advertising slogan - "Stand on the shoulders of giants" - is a nod to the scholars who have contributed to their fields over the centuries, providing the foundation for new intellectual achievements.

Taxonomy (from Ancient Greek: taxis "arrangement" and Ancient Greek: nomia "method") is the practice and science of classification or the result of it. Taxonomy uses taxonomic units, known as taxa (singular taxon). A resulting taxonomy, a taxonomy, or taxonomic scheme, is a particular classification ("the taxonomy of ..."), arranged in a hierarchical structure or classification scheme. Typically this is organized by supertype-subtype relationships, also called generalization-specialization relationships, or less formally, parent-child relationships, typically indicated by the phrase 'is a kind of' or 'is a subtype of'. In such an inheritance relationship, the subtype by definition has the same properties, behaviours, and constraints as the supertype plus one or more additional properties, behaviours, or constraints. For example: a bicycle is a kind of vehicle, so any bicycle is also a vehicle, but not every vehicle is a bicycle. Therefore a subtype needs to satisfy more constraints than its supertype. Thus to be a bicycle is more constraint than to be a vehicle. If other kinds of relationships between concepts are also included, a taxonomy is extended into an ontology. Thus various ontologies also include a taxonomy. This holds especially for the upper level ontologies (arrangements of generic concepts). (Excerpt from Wikipedia article: Taxonomy)

web app

A web application is an application that is accessed by users over a network such as the Internet or an intranet. The term may also mean a computer software application that is coded in a browser-supported programming language (such as JavaScript, combined with a browser-rendered markup language like HTML) and reliant on a common web browser to render the application executable. Web applications are popular due to the ubiquity of web browsers, and the convenience of using a web browser as a client, sometimes called a thin client. The ability to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity, as is the inherent support for cross-platform compatibility. Common web applications include webmail, online retail sales, online auctions, wikis and many other functions. (Excerpt from Wikipedia article: Web application)

information architecture

Information architecture (IA) is the art of expressing a model or concept of information used in activities that require explicit details of complex systems. Among these activities are library systems, Content Management Systems, web development, user interactions, database development, programming, technical writing, enterprise architecture, and critical system software design. Information architecture has somewhat different meanings in these different branches of IS or IT architecture. Most definitions have common qualities: a structural design of shared environments, methods of organizing and labeling websites, intranets, and online communities, and ways of bringing the principles of design and architecture to the digital landscape.

PHP is a general-purpose scripting language originally designed for web development to produce dynamic web pages. For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. It also has evolved to include a command-line interface capability and can be used in standalone graphical applications. PHP can be deployed on most web servers and as a standalone interpreter, on almost every operating system and platform free of charge. (Excerpt from Wikipedia article: PHP)

An electronic portfolio, also known as an e-portfolio or digital portfolio, is a collection of electronic evidence assembled and managed by a user, usually on the Web. Such electronic evidence may include inputted text, electronic files, images, multimedia, blog entries, and hyperlinks. E-portfolios are both demonstrations of the user's abilities and platforms for self-expression, and, if they are online, they can be maintained dynamically over time. Some e-portfolio applications permit varying degrees of audience access, so the same portfolio might be used for multiple purposes. An e-portfolio can be seen as a type of learning record that provides actual evidence of achievement. Learning records are closely related to the Learning Plan, an emerging tool that is being used to manage learning by individuals, teams, communities of interest, and organizations. To the extent that a Personal Learning Environment captures and displays a learning record, it also might be understood to be an electronic portfolio. (Excerpt from Wikipedia article: E-portfolio)

data mining

Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD), an interdisciplinary subfield of computer science, is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. Aside from the raw analysis step, it involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating.

E-Government (short for electronic government, also known as e-gov, digital government, online government, or connected government) is digital interactions between a government and citizens (G2C), government and businesses/Commerce (G2B), government and employees, and also between government and governments /agencies (G2G). Essentially, the e-Government delivery models can be briefly summed up as (Jeong, 2007): G2C (Government to Citizens); G2B (Government to Businesses); G2E (Government to Employees); G2G (Government to Governments). This digital interaction consists of governance, information and communication technology (ICT), business process re-engineering (BPR), and e-citizen at all levels of government (city, state/provence, national, and international).
