Web site building: domain names.
Materials for given article have been written based on own personal experience. Some moments seem disputable and are now checked in practice; therefore article information will be supplemented and specified further on.
Whence we get this www?
It is possible to find weight of guidelines in the Internet how to “unite” domain.com and www.domain.com. But except as how to make it, it would be useful to understand a little as well why. It could help to select appropriate solution from an offered variety.
At first, it is important to understand that www.domain.com – technical the same, as sub.domain.com though such state of affairs exists for absolutely other reason.
Ten or twelve years ago, World Wide Web was only one small part of the Internet, and the fastest PC has been grounded on 386 chips. They were not so fast and could not handle the loading most part, thus, there was a necessity to place various “parts” of the Internet on separate computers.
For example, server Apache took places on one computer, a mail server on other, and server FTP on one more. Each of computers responded on various IP address, but on the same domain name. In this domain name computers were differentiated on given tools (that was named then, “a computer name”). Thus, names of servers in the Internet started with “a computer name” on tools given to it: www.domain.com, mail.domain.com, and ftp.domain.com. (“Old residents” of the Internet, probably remember also such archaic tools as gopher.domain.com, in customizations of IE it still remained).
Today’s computers are, of course, much more powerful, and we can place all various “parts” of our services of the Internet in same “box” (principle Head&Sholders – “two in one bottle”.
Really, we often install some hundreds of domains, everyone with its own set of tools (http, ftp, a mail …), on the same server. Therefore now the prefix www is “antiques” and can be ignored. Trouble that, set of the software and the big directories (for example, Yahoo), automatically substitute www.domain.com even if you type domain.com, plus to it we have some billions persons which automatically print www before any domain name.
This digression to History, at least, for me, is represented interesting, but a unique important thing from it – that technical www.domain.com in the same way as sub.domain.com – are considered completely as various objects rather domain.com, but for the reasons stated above, usually www.domain.com and domain.com usually should show the same page, unlike sub.domain.com. The web user (web surfer) or the retrieval system (spider), at inquiry of page will receive the same code of the answer and will also fail to differentiate domains with www and without that.
Nowadays the online technologies are very popular. The Internet network is not only a place to entertain but also a spot to earn money. Whatever the reason is, to be presented in the Internet one needs a site. And this is when the question how to make a website arises. Those who are searching for details on how to build a website, should refer to the Web itself. There are lots of guides on how to make a website and related topics.
In any way, it wouldn’t be wise not to avail themselves of this opportunity given to us by modern technologies. Google and other search engines, social networks and forums, blogs – all of them could assist to find info on “ make a new website” and similar topics.
