Tim Berners-Lee, the man who invented the phrase WWW, believes that the Internet will continue to grow, and a “Web 3.0” will not be delayed to appear. The internet veteran believes that in the next stage the Internet will be transformed into a “semantic Web“, a place where computers will be able to select information according to the settings indicated by users and the...
Web 2.0 is a term that refers to a whole lot of interactive and collaborative aspects of the Internet, and here in particular of the World Wide Web, which appeared in nature from 2004 to 2005. Web 2.0, also called the “social web“, represents the second generation of intelligent web page development, which facilitates communication, provides secure information and different services...
The World Wide Web (known as the Web) is not synonymous with the Internet, but it is the most prominent part of the Internet, which can be defined as a technical-social system of interaction with people based on technological networks. The notion of a technical-social system refers to a system that improves human cognition, communication, and cooperation; Cognition is the prerequisite for...
An applet is a program written in Java that can display the results between well-defined boundaries in a web page. Thus, an applet runs in a rectangle of the size specified in the web page in which it is embedded. Java has been designed to provide a high degree of security. The ability to execute code taken from the Internet on the client’s computer can open Pandora’s box for it...
CorelDRAW is the most important graphics package under Windows. It allows the creation of beautiful illustrations, professional advertising, annual reports. It is an object-oriented drawing program. In many ways, it is similar to computer-aided design programs (AutoCAD). With its module PHOTO-PAINT, this program resembles the painting programs, where they use the graphics made through dots and...
Nowadays, the most used method of interacting with a Web server is that of the client/server architecture based on Web technology. The process of exchanging information used in Web technology does not differ from the process implemented by the standard client/server architecture, in which the server program manages the processing of the queries received from the client programs. In the process of...
ActiveX is a set of technologies from Microsoft that focuses on integrating and unifying the methods of representing and processing information from computer networks, built in accordance with the web architecture. The main idea of ActiveX technology consists of the identical means of accessing information from the network, in which web technology was selected as the basis for unifying these...
Chimera – a demonstrative visual programming by demonstration. Chimera is an example of how imperative programming is supported in LPVs by having the programmer demonstrate his or her desired actions. D.J. Kurlander designed the system in his doctoral thesis. In the case of Chimera, the “programmer” is an end-user, as a result, it is also an example of LPV intended to improve...
Cocoa (initially called KidSim) is a rules-based LPV, in which the programmer specifies rules for demonstrating a postcondition starting from a precondition. The “programmers” targeted are children, and the associated field is the specification of graphics simulations and games. Cocoa is a complete Turing language, except that its facilities were not designed for general-purpose...
Forms / 3 – Forms / 3 is an example of LPV based on the spreadsheet paradigm, implemented by Margaret Burnett in 1991, as a prototype of her dissertation work. In this case, the programmer realizes his program by creating a form and specifying its content. This paradigm is commonly used in commercial spreadsheets, where the form is in the form of a marked grid, and the content is specified...
