Uniform resource locator
Universal resource locator
URLs are the Internet equivalent of addresses. How do they work? Like other types of addresses, they move from the general to the specific Take this URL, for example:
http://www.jayamwebsolutions.com/services.html which speaks about the services of Jayam Web Solutions
In a general sense, this term describes information-carrying capacity. It can apply to telephone or network wiring as well as system buses, radio frequency signals, and monitors. On a more human level, the term can describe a person's capacity for dealing with multiple projects ("I'd like to update this database, but I don't have the bandwidth.").
Bandwidth is most accurately measured in cycles per second, or hertz (Hz), which is the difference between the lowest and highest frequencies transmitted. But it's also common to use bits or bytes per second instead.
If you can read this, it's highly likely that you're using a Web browser. In brief, a browser is your interface to the World Wide Web; it interprets hypertext links and lets you view sites and navigate from one Internet node to another. Among the companies that produce browsers are NCSA Mosaic, Netscape, and Microsoft, as well as commercial services like CompuServe, Prodigy, and America Online.
» What is cache?Caches come in many types, but they all work the same way: they store information where you can get to it fast. A Web browser cache stores the pages, graphics, sounds, and URLs of online places you visit on your hard drive; that way, when you go back to the page, everything doesn't have to be downloaded all over again. Since disk access is much faster than Internet access, this speeds things up. Of course, disk access is slower than RAM access, so there's also disk caching, which stores information you might need from your hard disk in faster RAM.
» What is a database?A database can be as simple as a shopping list or as complex as a collection of thousands of sounds, graphics, and related text files. Database software is designed to help users organize such information. While early "flat" databases were limited to simple, searchable rows and columns, modern relational databases allow users to access and reorganize data in a variety of ways. Even more advanced databases let users store and retrieve all kinds of nonstandard data, from sound clips to video.
» What is a cookie?According to Netscape, cookies are a "general mechanism which server side connections can use to both store and retrieve information on the client side of the connection." In English, that means cookies are small data files written to your hard drive by some Web sites when you view them in your browser. These data files contain information the site can use to track such things as passwords, lists of pages you've visited, and the date when you last looked at a certain page.
» What is a domain name?Looking for a domain name? You'll find it to the right of the @ sign in an email address, or about ten characters into a URL. Desert Web Design's domain name is desertwebdesign.com. Domain names are issued by the National Science Foundation (NSF), and they come with different extensions based on whether the domain belongs to a commerical enterprise (.com), an educational establishment (.edu), a government body (.gov), the military (.mil), a network (.net), or a nonprofit organization (.org).
» What is FTP? (file transfer protocol)This Internet protocol is used to copy files between computers--usually a client and an archive site. It's old-fashioned, it's a bit on the slow side, it doesn't support compression, and it uses cryptic Unix command parameters. But the good news is that you can download shareware or freeware apps that shield you from the complexities of Unix, and you can connect to FTP sites using a Web browser.
» What is an OS? (operating system)A computer by itself is essentially dumb bits of wire and silicon. An operating system knows how to talk to this hardware and can manage a computer's functions, such as allocating memory, scheduling tasks, accessing disk drives, and supplying a user interface. Without an operating system, software developers would have to write programs that directly accessed hardware--essentially reinventing the wheel with every new program. With an operating system, such as Windows NT or Mac OS 8, developers can write to a common set of programming interfaces called APIs and let the operating system do the dirty work of talking to the hardware.
» What does POP mean? (Post Office Protocol)The current champ in Internet email mailbox access standards, but its limitations--basically, you connect to a server and download all your messages, which are then deleted from the server--discourage flexibility. Of course, some clients let you leave all messages on the server, and/or refuse to download messages above a certain size. Still, as messages become longer--with multimedia (such as sound or video) objects and the likes--we'll want some flexibility in what we retrieve and when we retrieve it. That's where IMAP comes in. The current version of POP is POP3.
