Internet Definitions

The definitions listed below are terms that have been used throughout this website. Simply click on any Internet term that is in blue and underlined, and you will be brought to this page.

Blog Definition

A blog is a lot like a journal except it is generally intended to be read by others. The topics for blogs vary greatly; some being about day to day activities and others taking a more corporate or political slant. There is no defined or widely accepted format and so blogs range from one liners that the author adds every few hours to relatively long, well thought out arguments for or against a topic of interest.

Usually, users that are interested in a particular blog can subscribe to the blog and receive updates automatically through the use of an RSS feed aggregator (also known as a news aggregator). Unlike mailing lists, you do not need to provide an e-mail address and if nothing else, blog subscriptions protect your e-mail address from spam.

Typically, a blog contains posts that are more often than not presented in reverse chronological order. A blog, at a minimum, consists of the following components:

  • Title of the post
  • Body area for the main content
  • Comment area where readers can discuss the posting
  • Category to help with grouping posts
  • Permanent link aka permalink which is the URL of the full post
  • Post or publishing date

Blogging Definition

Blogging is the verb (action word) that has been coined by people to refer to the act of adding an entry or entries to a blog (see blog definition). Those that actively engage in blogging write entries almost hourly, but there is no rule for how often a blog entry must be added. It is entirely up to the individual.

BMP Definition

BMP (short for bitmap) is a graphic format used internally by the Microsoft Windows graphics subsystem, and used commonly as a simple graphics file format on that platform. BMP files are usually not compressed, so they are typically much larger than compressed image file formats such as JPEG or PNG. Despite its shortcomings, the simplicity of BMP and its widespread use in Microsoft Windows and elsewhere, as well as the fact that this format is well-documented and free of patents, makes it a very common format. As such, many image programs are likely to be able to read in BMP files.

e-Business Definition

e-Business (electronic business) is, in its simplest form, the conduct of business on the Internet. It is a more generic term than e-commerce because it refers to not only buying and selling but also servicing customers and collaborating with business partners.

IBM, in 1997, was one of the first to use the term when it launched a campaign built around the term. Today, many corporations are rethinking their businesses in terms of the Internet and its capabilities. Companies are using the Web to buy parts and supplies from other companies, to collaborate on sales promotions, and to do joint research. Exploiting the convenience, availability, and global reach of the Internet, many companies, both large and small have already discovered how to use the Internet successfully.

e-Commerce Definition

e-Commerce (electronic commerce) is the buying and selling of goods and services on the Internet, especially the World Wide Web. In practice, this term and a newer term, e-business, are often used interchangeably.

When the Web first became well-known among the general public in 1994, many journalists and pundits forecast that e-commerce would soon become a major economic sector. However, it took about four years for security protocols to become sufficiently developed and widely deployed (during the browser wars of this period). Subsequently, between 1998 and 2000, a substantial number of businesses in the United States and Western Europe developed rudimentary websites.

Although a large number of "pure e-commerce" companies disappeared during the dot-com collapse in 2000 and 2001, many "brick-and-mortar" retailers recognised that such companies had identified valuable niche markets and began to add e-commerce capabilities to their websites.

HTML Definition

HTML (Hypertext Markup Language) is the markup language used to construct websites. Web browsers use it to interpret and compose text, images and other material into visual or audible web pages.
Most websites these days have moved on from HTML and now use XHTML (extensible hypertext markup language)

HTML isn't really a programming language as it is missing many of the standard features associated with programming languages. It is more a way to describe how things should appear in a web browser. With it you can make sections of text bold or make the typeface bigger.

Purists believe that HTML shouldn't be used to specify content layout. They feel that the content should flow freely and fill the screen in whatever way best suits the end-user. However, in practice, most web designers do attempt to control layout, feeling that expressing their message in a specific and controlled manner is a worthwhile pursuit.

To build features such as forums, shopping carts and registration forms requires technologies other than HTML. It is best to think of HTML as the glue that binds all this functionality into something that a web browser can interpret and display for the end-user.

GIF Definition

GIF (Graphics Interchange Format) is a bitmap image format for pictures with up to 256 distinct colours. The format was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web. GIFs are compressed files, and were adopted to reduce the amount of time it takes to transfer images over a network connection.

A GIF file employs lossless data compression so that the file size of an image may be reduced without degrading the visual quality. Contrast this to the JPEG file format which discards data to achieve file size reductions. The GIF format's 256-color limitation makes it unsuitable for photographs. The GIF format is normally used for diagrams, buttons, and drawings that have a small number of colours, while the JPEG format is used for photographs.

Many software vendors were caught by surprise when it was revealed that the GIF format had been patented by Unisys and that they would have to pay royalties for writing programs that generated (or displayed) GIF files. The desire for a comparable format with fewer legal restrictions (as well as fewer technical restrictions such as the number of colours) led to the development of the PNG (Portable Network Graphics) standard. Although the GIF patents will expire in the near future, PNG is still touted as a technically superior alternative, and has become the third most common image format on the web.

Internet Definition

The Internet, sometimes called simply "the Net," is a worldwide system of computer networks – a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. Government in 1969 and was first known as the ARPANET. The original aim was to create a network that would allow users of a research computer at one university to be able to "talk to" research computers at other universities. A side benefit of ARPANET's design was that, because messages could be routed or rerouted in more than one direction, the network could continue to function even if parts of it were destroyed in the event of a military attack or other disaster.

Today, the Internet is a public, cooperative, and self-sustaining facility accessible to hundreds of millions of people worldwide. Physically, the Internet uses a portion of the total resources of the currently existing public telecommunication networks. Technically, what distinguishes the Internet is its use of a set of protocols called Transmission Control Protocol/Internet Protocol (TCP/IP). Two recent adaptations of Internet technology, the intranet and the extranet, also make use of the TCP/IP protocol.

Using the Web, you have access to millions of pages of information. Web browsing is done with a Web browser, the most popular of which are Microsoft Internet Explorer and Netscape Navigator.

ISP Definition

An Internet Service Provider (ISP) is the company that sits in between the Internet and someone that wants to use the Internet. These companies are often the phone or cable companies themselves, but sometimes they are independent providers of Internet access. Of course, if they're independent vendors they still need to work with the phone and cable companies since they are the ones that have the communications infrastructure.

Originally, ISPs required users to dial in much the same way that you dialled a phone. However, over the last several years it has become more common for connections to be always on or to at least require only a second or two to be established.

At the consumer level, ISPs provide Internet access along with basic services such as e-mail accounts, spam filtering, and sometimes anti-virus software. At the corporate level, ISPs provide a guaranteed level of service, configuration flexibility, and a lot of bandwidth. As you can imagine, corporations pay much more than consumers.

JPEG Definition

JPEG (pronounced jay-peg) is a commonly used method of compressing photographic images. The compression algorithm is "lossy" in that information is removed from the image to assist with decreasing the file size. The greater the compression, the more information is discarded. Files that have undergone JPEG compression usually have extensions such as .jfif, .jpeg, or jpg.

The name stands for Joint Photographic Experts Group. JPEG itself specifies only how an image is transformed into a stream of bytes, but not how those bytes are encapsulated in any particular storage medium. JPEG is the most common format used for storing and transmitting photographs on the World Wide Web. It is not as well suited for line drawings and other textual or iconic graphics because its compression method performs badly on these types of images. It is better to use the PNG and GIF formats for such purposes.

Most digital cameras also create files that are in JPEG format. A testament to the popularity of the standard.

SPAM Definition

Generally speaking, spam is unsolicited, bulk e-mail. Similar to how your mailing address is used, an e-mail address gets on to one or more mailing lists which are then used repeatedly to send advertising. Some of the e-mails are legitimate sales offers, but a large portion seems to be of dubious value. It's this second type that often annoys people enough to form anti-spam groups and to ask governments to create anti-spam legislation.

Unlike junk mail which the senders must pay to have delivered, there is no charge for sending spam. Spam actually costs companies and end-users money in terms of time and potentially increased Internet fees associated with the added bandwidth and hardware required to process all the spam.

Spam has become such a significant problem that a niche market has been created to develop anti-spam technologies.

URL Definition

A uniform resource locator (URL) is a way of unambiguously describing the location of something on a network. This something can be a web server, printer, FTP server, or even another desktop computer. Most commonly, a URL refers to a website or web page.

The URL was a fundamental innovation in the history of the Internet. It was first created by Tim Berners-Lee in 1992 to allow document authors to establish hyperlinks on the World Wide Web. Since 1994 the URL concept has been subsumed into that of the more general Uniform Resource Identifier (URI), but URL is still a widely used term.

WWW (World Wide Web) Definition

A technical definition of the World Wide Web is; all the resources and users on the Internet that are using the Hypertext Transfer Protocol (HTTP).

A broader definition comes from the organisation that Web inventor Tim Berners-Lee helped found, the World Wide Web Consortium (W3C).

"The World Wide Web is the universe of network-accessible information, an embodiment of human knowledge."

XHTML Definition

XHTML (Extensible Hypertext Markup Language) is the markup language used to construct websites. Web browsers use it to interpret and compose text, images and other material into visual or audible web pages.
Most early websites used HTML but XHTML 1.0 use became a World Wide Web Consortium (W3C) recommendation on January 26, 2000.
