Internet Definition: The Internet, or simply the Net, is the publicly accessible worldwide system of interconnected computer networks that transmit data by packet switching using a standardised Internet Protocol (IP) and many other protocols. It is made up of thousands of smaller commercial, academic, domestic and government networks. It carries various information and services, such as electronic mail, online chat and the interlinked web pages and other documents of the World Wide Web. The Basics A Website: One or more files (pages) stored on a computer (a "server") that can be accessed via the Internet. Every website has a "home page", which is generally designed as the file visitors first see when coming to the site and which gives an idea of the site's contents. All files on a website usually contain textual or graphical "links" that can be clicked using an input device such as a mouse to move to other files, either within the site or on another one. E-mail: The most popular application on the Internet, email allows you send and receive text, HTML, images and other data files. Email is known as the "killer-app" because it is the most popular online activity and a vital tool for electronic commerce. FTP: File Transfer Protocol (FTP), a standard Internet protocol, is the simplest way to exchange files between computers on the Internet. FTP is commonly used to transfer Web page files from their creator to the computer that acts as their server for everyone on the Internet. It's also commonly used to download programs and other files to your computer from other servers. Online Chat: Online chat is a generic term for what are now mostly known as instant messaging applications - computer programs that enable two-way typing to connect users to each other. E-Commerce: Electronic
commerce - the conducting of business communication and transactions over
networks and through computers. Specifically, ecommerce is the buying and
selling of goods and services, and the transfer of funds, through digital
communications. Definition: The status regarding whether two computer systems are communicating with each other over either a local network or over the Internet. When computers are communicating with each other, there is said to be "connectivity" between them. Dial up: 'Dialup Access' or a 'Dialup Account' is when a modem is used to gain access to the Internet via a network. A dial-up connection to the 'Net is almost as slow as it gets. Dial up access can be either analogue or ISDN. Analogue Dial up: An Internet connection over standard phone lines, using a modem, with a maximum speed of 56k. ISDN Dial up: Integrated Services Digital Network (ISDN) is a type of circuit switched telephone network system, designed to allow digital (as opposed to analog) transmission of voice and data over ordinary telephone copper wires, resulting in better quality and higher speeds, than available with analog systems. ISDN supports data transfer rates of 64 or 128Kbps through an ISDN modem. Broadband: Broadband comes from the words "broad bandwidth" and is used to describe a high-capacity, two-way link between an end user and access network suppliers capable of supporting full-motion, interactive video applications. ADSL: ADSL (Asymmetric Digital Subscriber Line) is a technology for transmitting digital information at high bandwidths on existing phone lines. Unlike regular dialup phone service, ADSL provides a continuously-available connection. ADSL is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. ADSL simultaneously accommodates analog (voice) information on the same line. ADSL is generally offered at downstream data rates from 512 Kbps to about 6 Mbps. Wireless Internet: A broadband internet connection using radio waves between a Wisp (Wireless Internet Service Provider) and a client network. Website Hosting The World Wide Web is a massive collection of web sites, all hosted on computers (called web servers) all over the world. Because of the web's uniquely global nature, a web site should be accessible 24 hours a day, seven days a week. Rather than pay to have a 24/7 dedicated Internet connection to an in-house web server, many people opt to host their sites with a web hosting provider. Web hosting clients simply upload their web sites to a shared (or dedicated) web server, which the ISP maintains.
