Browsers are software programs that render web pages and help you move through the web.
The browser that triggered the World Wide Web explosion was Mosaic, a public domain graphical user interface (GUI) from the National Center for Supercomputer Applications (NCSA). Released in 1993, Mosaic made it possible to design documents containing images for display over the internet. Up to that point, an internet document was basically just a bunch of text on a server. In 1994, Mosaic ship-jumper Marc Andreessen released Netscape 1.1, following Mosaic’s successful lead, by distributing the browser free of charge on the internet in order to establish a wide user base.
Popular web browsers today include Internet Explorer, Firefox, Safari and Opera. See Browser Charts for information on some of their differences.
The term “eyeballs” is a quaint reference to the number of people who see, or “lay their eyes on,” a certain advertisement. When buying radio time, marketers refer to “ears” instead of “eyeballs.”
Another elusive Holy Grail of online business, micropayments let content providers charge very small fees (some fraction of a penny, say) for access to a site or other electronic information. The aggregated payments are then deducted from a user’s ecash account or credit card, making the experience highly fluid. However, unless you rack up a lot of micropayments, the cost of processing each transaction is far greater than the revenue gained. On top of that, your users have to be willing to set up an ecash account.
PHP is an open-source scripting language that is embedded alongside HTML to perform interactive functions, such as accessing database information. PHP is similar to Microsoft’s active server page technology, but is used primarily on Linux web servers (or Windows servers with add-on software). An HTML page that has PHP script usually has a “.php” extension. Visit Webmonkey’s Tutorial:PHP Tutorial for Beginners to learn how it works.
