Servers are systems which are used to manage computer networks. They are able to perform all kinds of activities and they could be dedicated to a particular job. For instance, a file server stores the files which contain data and information that belong to a certain network. An example of this would be Microsoft's Exchange Server, which is dedicated to handle business mails as well as other types of business communication. Another example would be multiprocessor servers that handle several tasks simultaneously such as managing mailboxes, storing data and other tasks.

Servers have been basically created to be able to have better management of data. They make the whole process of information management faster and safer. However, there are also other applications for servers. These would include the provision of access to the Internet. A lot of people make use of a server, which has been provided by a company, which manages the availability of web connectivity and other services for them. This actually makes it a lot cheaper and easier to use so that we can stay connected online.

Servers are also useful to manage official communication. Since virtually all offices today are running on LAN servers, companies are able to connect and manage all their computers centrally and conveniently. It also serves as a cheaper, simpler and safer method to keep everything well managed.

Servers also permit remote access. If an individual has to access a computer in the main office and he or she is traveling, that individual can access the information that he or she needs from that computer using a computer at the current location which is also connected to the same server where the other one is connected to.

Importance of a navigation scheme

One of the most important tasks when developing your website is creating a navigation system that is effective and easy to use. People have a tendency to try to include everything in the navigation tree all at once. Instead they should follow the same process as setting up the structure for the site and break it down in levels. This would be information relevant to the homepage that directs visitors to the main sections of the site. From the main sections of the site, the user gains access to the sub sections containing content pertinent to that section only. Remember to always include links back to the main sections and your homepage on every page in your site. While you are creating your navigation setup, try to look through your user's eyes. Remember, you are the one creating the structure, so you are biased in your opinions. If you think about what someone else might say or do, then you are one step ahead of the game.

As you create you website navigation, make sure that links can be added in the future with no difficulty. You must always keep in mind that your site must be flexible and open to change because it is never completed. All links should be clear and to the point. It makes no sense to have your visitor try to figure out where they are going. They should be able to quickly look for what they want and then access it in a timely and efficient method. There is a better chance of a visitor going somewhere else if it takes too long for them to find the information they are looking for. Your navigation scheme should stick out and be located in a common spot on every page of your site. Consistency allows your visitors to focus on the content instead of trying to figure another navigation system for the same site.

Linear navigation

Linear navigation provides the same capabilities as your forward and back button on your browser. With this navigation style, you cannot jump around and skip pages. Reading a book or viewing a PowerPoint presentations are also examples of linear navigation. As you read through the pages, it makes no sense to jump around or you might miss an important piece of information. People who create sites with this style often are directing the visitor from a starting point to a predetermined end in a step by step fashion. Your links will not allow the user to anywhere other than where you want.

Hierarchical navigation

Hierarchical navigation allows the visitor to go from a homepage to the main sections of your site and then to the subsections. Visitors can travel through your site without any restrictions. This type of navigation ties all the areas of your site together so any page can be accessed from another in as few clicks as possible. Hierarchical navigation is best used on sites that are filled with information and to be utilized like a library.

Sitemaps for navigating through your website

Sitemaps provide a list of organized links to the content of your website. The same way a table of contents tells you what is inside a book, a sitemap does the same for your website. Your visitors are given a one page view of the information structure that your site is based on. Sitemaps are not meant to be your websites primary navigation but more as a compliment to it.

Navigation bars

A navigation bar gives your visitors the ability to move between the different sections of your website. It should be placed on every page of your site and should be consistent as well. Placement of the navigation bar is entirely up to you. The navigation bar can go on the left side of your page because most people read from left to right. It can also be placed on the top of your page so it is the first thing your visitors see. Some people place it on the right hand side of the page intentionally making a visitor browse through content to then be able to navigate the rest of the site.

Theme and navigation links

The theme for a website is created with the way you use color, fonts and images. During the theme creation process, remember to not clutter your pages with unnecessary content that will draw your visitor's attention from the main content. There are many ways to create a theme. One example might be a newspaper look consisting of black and white colors with a plain font. Themes give a website character and often leave a strong visual impression on the visitor. Your website theme needs to be used on all your pages which helps tie your site together.

Navigation

Navigation of a website should be an easy process and not require the visitor to take much time in figuring out how to move through your site. Visitors have come to your site looking for information and should be able to find it easily. If a visitor has to waste time figuring out how to get what they want, they will go to another site. Navigation is not just for people, but search engines as well. Set up the navigation to allow search engines to follow the links to index your entire website. Your navigation scheme should appear in the same place on all pages. When a visitor navigates through your site, make sure they can flow through it. Do not set it up so a visitor has to use the back button of the browser to access another page. Through navigation, your visitor will have access to pages in your site, to other sites and to different sections of the pages on your site. You will need to place navigation menus in more than one area on your pages. There are many good ways to help the visitor move through your site. The most simple is a text link. The next is a navigation bar placed on the top or sides. Another is the use of graphic buttons created to help compliment the overall look of your site. It is always good idea is to include links at the bottom of your page in case someone does not feel like scrolling back to the top. Through navigation, your visitor should be able to get where they want quickly, know where they currently are on your site and be able to access other pages on your site for additional information.

Website Accessibility means the website accessible to all the users in the web including visitors with disability. Many website owners know that their website is available in the internet for visitors to access information but possibly may not know whether their website is easily accessible and even be unaware about Disability Discrimination Act (DDA).

According to Disability Discrimination Act (DDA), all the business should make their services accessible to disabled users. There is also a section in DDA which addresses that if a business offers an online service, even the information is on a single page, then the business is responsible for making an effort to make this information accessible to disabled users.

All new websites that are designed and developed should now follow the W3C (World Wide Web Consortium) and Web Content Accessibility Guidelines (WCAG) against which the accessibility of the website is measured. But when the website is found isn't complaint, then anybody can sue you legally, if they want to.

By following these guidelines, you enhance the professional look of your website, provide access to visitors who previously had not no choice, thus increasing your business prospects and finally not to forget, your business is legal.

Some basic Guidelines to increase the accessibility of the visitors

Validate HTML and CSS: To check if the HTML and CSS used is valid, W3C validator can be used. It is necessary that websites are checked as the validator automatically tells you about any errors and accessibility issues in the web pages.

Image and alternative text: For browsers which don't support images, alternative text can be used to explain what the image is about as the user will only see the text.

Resize font text: Most of the internet browsers use Internet explorer to search for information. If the size of the text can be increased by choosing the font size to the largest then it means that your website is accessible to visitors.

Use of Java script: Websites are not easily accessible when java script is disabled. Mostly people have the java script support switched off, if that's the case then make sure that you use the Java script sensibly and unnoticeably.

Check for the following,

1. Website is accessible without the use of a mouse

2. Website has a Sitemap

3. Website has link text relevant to the content (blind users use tabbing while browsing websites from one link to the other)
