Web site structure has followed a relatively simple pattern for many years. The basic design pattern is very simple a header, a left column and possibly a right column depending on the screen space available.
In some instances the left column is translated to the right column. Navigation of the site is usually within the a column or beneath the header.
The real reason to for web designers to maintain this approach is very simple - web site visitors expect a familiar format whereby they can navigate the site - and that is all.
These terms 'static' and 'dynamic' are a general reference to web pages which either mixed with functionality ie 'Static' or appearance separated from functionality ie 'Dynamic'.
'Static' refers to hard coded page where appearance and content are mixed ie are intermingled with content and cannot be separated. If a change of content is required it is necessary to review the page, make the necessary changes and upload (by FTP) the new page to the web server. This is the most common client - web master scenario. For every page change the web master charges accordingly. These charges vary immensely but, there is a definitely a charge.
'Dynamic' refers to a page which is composed from possibly several different sources. Page content is usually stored in a data base. Which is extracted on request and served as the whole or part of the page,
In effect the web page can be composed (potentially) of a multiple of sources, including the content of the site date base but, also it is possible to include other, off site resources such as 'youtube'.
Whatever the classification such as dynamic or static, Site owners cannot in the majority make amendments or changes to their site without using the web master as a go between. The reason for this is very simple - lack of knowledge!
For instance, how many site owners know the access code for the the domain registrar? Very few I would suppose. In fact how many know what a domain registrar is? Moreover, what would they do with it if they had it? Well, he who controls the registration record controls the domain, in English that means if you are a site owner without this information you could be in a very difficult position.
It is simple really, a domain registrar, registers your domain on the world wide web, for which he charges a fee. Depending on the domain name extension, costs vary. Tucked away in every registration record is something called D.N.S. It is well beyond the focus of this article to dwell on the intricacies of D.N.S. However, simply put DNS provides a pointer to the web host.
