 * __ Ivan’s Knowledge of da technology __**

A common type of Internet server that stores PC office applications, databases, or other applications and makes them available to client programs that request them. || A company that manages and delivers application services on a contract basis. || Short for Web log, a personal Web page that often carries diary- like entries or political commentaries. Blogs are fast proliferating as new software allows users to create Web pages without having to learn the technical details of HTML and Web authoring. || An Internet connection such as DSL or cable modem that offers higher bandwidth, and therefore faster transmission speed, than standard modem connections. || E-commerce transactions that involve businesses providing goods or services to other businesses. || E-commerce transactions that involve businesses providing goods or services to consumers. || A type of broadband Internet connection that uses the same network of coaxial cables that delivers TV signals. || Small files deposited on a user's hard disk by Web sites, enabling sites to remember what they know about their visitors between sessions. || A term used to describe the Internet and other online networks, especially the artificial realities and virtual communities that form on them. First coined by William Gibson in his novel, Neuromancer. || A Web site that can display dynamic, changeable content without having constantly redesigned pages, due to an evolving database that separates the site's content from its design. || A system for purchasing goods and services on the Internet without using credit cards. || A term that describes the divide between the people who do and do not have access to the Internet. || A type of broadband connection to the Internet offered by phone companies. || A dedicated, direct connection to the Internet through a LAN, with the computer having its own IP address. || Business transactions through electronic networks. || A specialized server that acts like a local post office for a particular Internet host. || Extensible Markup language, a language that enables Web developers to control and display data the way they control text and graphics. Forms, database queries, and other data-intensive operations that can't be completely constructed with standard HTML are much easier with XML. || Private TCP/IP networks designed for outside use by customers, clients, and business partners of an organization. These networks are typically for electronic commerce. || A communications protocol that enables users to download files from remote servers to their computers and to upload files they want to share from their computers to these archives. || Software that, for the most part, keeps offensive and otherwise inappropriate Web content from being viewed by children, on-duty workers, and others. || A form of distributed computing in which not files but processing power is shared between networked computers. || An HTML document is a text file that includes codes that describe the format, layout, and logical structure of a hypermedia document. Most Web pages are created with HTML. || An alternative Internet-style network that provides faster network communications for universities and research institutions. || A business that provides its customers with connections to the Internet along with other services. || Connecting different types of networks and computer systems. || A self-contained intraorganizational network that is designed using the same technology as the Internet. || A platform-neutral, object-oriented programming language developed by Sun Microsystems for use on multiplatform networks. || A Web scripting language similar to, but otherwise unrelated to, Java. || Dial-up Internet connections; named because they don't offer much bandwidth when compared to other types of connections. || Standards not owned by any company. || The standard technique used to send information over the Internet. A message is broken into packets that travel independently from network to network toward their common destination, where they are reunited. || See peer-to-peer model. || A software extension that adds new features. || A Web site designed as a Web entry station, offering quick and easy access to a variety of services. || Technology in which browsers on client computers pull information from server machines. The browser needs to initiate a request before any information is delivered. || Technology in which information is delivered automatically to a client computer. The user subscribes to a service and the server delivers that information periodically and unobtrusively. Contrast with pull technology. || A broadband technology available through many of the same satellite dishes that provide television channels to viewers. For many rural homes and businesses, satellite Internet connections provide the only high-speed Internet access options available. || Sound files that play without being completely downloaded to the local hard disk. || Video clip files that play while being downloaded. || An HTML-like language designed to make it possible to link time-based streaming media so that, for example, sounds, video, and animation can be tightly integrated with each other. || The address of a Web site. || Networks that use encryption software to create secure "tunnels" through the public Internet. || Programs such as Macromedia's Dreamweaver that work like desktop publishing page layout programs to allow users to create, edit, and manage Web pages and sites without having to write HTML code. || An invisible piece of code embedded in HTML-formatted email that is programmed to send information about its receiver's Web use back to its creator. || See blog. || A server that stores Web pages and sends them to client programs-Web browsers-that request them. || New kinds of Web-based applications that can be assembled quickly using existing software components. || Part of the Internet, a collection of multimedia documents created by organizations and users worldwide. Documents are linked in a hypertext Web that allows users to explore them with simple mouse clicks. || Markup language that combines features of HTML and XML; its advantage is its backward compatibility with HTML. || **• means for blocking access to information** Some ISPs may prevent certain sites from being accessed. This is generally done for the users benefit to prevent them seeing unnecessary/bad things but they are sometimes annoying as they stop people accessing what they want.

**• comparison of Internet and Intranet** An intranet is a private computer network that uses the internet technologies to share its information with its members. **• encryption methods** Converting sensitive data that is sent via the internet into a code so that if it is intercepted, its message will remain unknown.

**• the limiting effect of bandwidth** no matter how good the webpage looks, what the user sees is determined by the internet bandwith that the user has. (how fast the internet is) program which can be transmitted between computers via networks (especially the Internet) or removable storage such as CDs, USB drives, floppy disks, etc., generally without the knowledge or consent of the recipient that are capable of reproducing themselves and usually capable of causing great harm to files or other programs on the same computer.
 * • viruses **

**• online services, e-commerce, banking, health, libraries** Many if the services that people have to leave their homes to acquire are now at their fingertips as the internet has enabled people to transfer money to each in exchange for goods and services from their own house.
