Things which exist on one's personal computer are referred to as "client side", and on the web host as "server side". The average internet user might have first heard "client" in the context of applications installed on the personal computer, such as "email client". Those mail systems which can be used from anywhere are "web mail", and exist on the server side.

In practical terms, all your office suite programs, media players, programs to edit images, most games, and so forth, are probably client side, although "utility" type functions are evolving on the server side. For example, users can now share data on server side spreadsheets and word processors.

Most browser function is defined on the client side, perhaps with some JavaScript add-ons for interaction, calendars, multi-level menus, animated graphics, et cetera.

Business enterprise level content management, databases, store systems, and much more are on the server side. Server side programming can range from simple CGI scripts ("Common Gateway Interface") written in a variety of languages, such as Perl. Large databases can be built in the popular open-source MySQL, and accessed through interfaces programmed in PHP.

First embodiments of such CGI functions started a new copy of the executing module for each command request. To avoid server shutdown from excessive workload, host programmers have evolved better ways, but these need not concern us ordinary mortals.

Fortunately for this author, a web site builder does not need to be an expert in all those server side tools in order to use them. Most hosting companies now offer access to pre-installed modules. Persons wanting better features can purchase modules from third parties to upload and install, such as shopping carts, which are backed by support staff, user, or similar.

If the site builder lacks a very fast connection to the server, s/he can install client side copies of operating systems for SQL, PHP, other... to emulate behavior on the host. Sometimes the emulation is less than perfect, such as with different release generations, so adjustments may be needed after upload.

Why would anyone bother to do this? One reason is that PHP can take over parts of HTML coding, such as with "include files" which represent often used sections of header, footer, body, or serve more robustly than JavaScript for interactivity and utility functions.

If the connection is fast, however, present day "shared hosting" and "virtual private/dedicated servers" make it very difficult for one domain owner to break the system for other users. And only privileged employees have access to the power switch. VPS allows power users to get more behind the scenes than can the SH customer.

Caveat: Whether your HTML writing is done directly on host account or on personal computer for upload, keep an off-site copy against the day your hosting company drops or back levels your content. It will happen.

What ever the approach a person uses for working on the internet, all these elements are examples of "distributed processing", a concept which some large mainframe computer manufacturers had hoped would never be realized. Now that the small guys and gals have forced the issue, by using ever more powerful personal computers in place of dumb terminals, the big dogs have learned to love and profit from it.

If you are considering building a web site for your business, then you will more than likely like it to rank in the search engines There are many factors that influence website rankings and many of these factors can be implemented while you are creating your website. Optimizing your website properly for your business will ensure a more successful site.

Have you heard the concept "Content is King"? The search engines are becoming more selective at who ranks highly and want to provide the best content for each search term. They are looking for high quality content that is continually updated and provides a quality experience for their searchers. It makes no difference whether you have a content site or a physical product site. Content is "King" as far as the search engines are concerned. By providing quality content and/or good descriptive descriptions of products you sell you will be helping your customers and you may just help yourself at ranking.

One mistake many new webmasters make is to over optimize their web page by using too many keywords. If you are excessive with your keywords, your web page will not read well and the search engines my penalize you. It is considered spamming when your techniques are questionable even if that wasn't your intention. There are other techniques that are considered unethical including hiding text, and redirects. Just write for your visitor and don't try to over optimize your web page.

Another thing to keep in mind that may cause you problems is the use of frames. Make sure you know how to use frames correctly before using them on your website. If the proper frame context is established, then the search engines can send visitors to your site. However if you use frames incorrectly the spiders for them will not be able to crawl your web page and or website.

During web site building, you should also consider the depth of your site. Search engines have spiders that crawl through the web pages and find the necessary keywords. If you do not setup the correct linking structure throughout your website the spiders may not be able to crawl your entire site. One of the best practices when setting up your websites' structure is to include a sitemap that lists all the web pages that make up your website and then link your sitemap to your homepage. This will help ensure that the search engines can crawl your site.

With proper planning and a little research you will be able to build a professional site that the search engines love.

Rack mount servers are essentially systems that are in a modern server and are used to mount different sizes and kinds of electronic modules. Rack mount servers would be ideal for individuals who need to set or probably pack a couple of personal computers to a smaller space.

This kind of server is commonly employed in many areas and countries globally for a lot of purposes and reasons. Rack mount servers are used wherever an application of computers has to be used for a wider and larger application, which could star t from video editing suites to computer animations to the other kinds of three-dimensional tasks.

These rack mount servers are also utilized for the installation of different Internet service providers or ISPs in the field of telecommunications as well as in the other types of communication and for different database houses. They are created and are designed to be able to fit in an open PC or probably in a closed cabinet. One advantage for the use and implementation of a rack mount server would be that they could really prove to be very functional and useful if someone needs or wants to save some space. The space-saving design of rack mount servers allows the user to maximize the space he or she has.

The role of these servers is crucial, as proper and adequate setting and support of hardware to a well-built storage space would ensure that they are would be well-protected from any external elements and other factors.
