A web page consists of two main areas: the head and the body. The body contains all of the elements which will be displayed in the browser window and the majority of which will be visible to the user. The head element, by contrast, contains information about the web page; meta information as it is sometimes called. In this article, we will look at the different ways in which Dreamweaver allows you to modify elements within the head of a web page, beginning with the title.
The title element should contain a broad description of the content of the page. It is extremely important that each page should have a title and that the title be pertinent to the page that contains it. Dreamweaver automatically adds a title element to every new page containing the text “Untitled Document”. Perhaps the easiest way of modifying the default title in Dreamweaver is simply to enter a title in the Document Title box of the Document toolbar which is normally displayed at the top of the page. An alternative is the choose Modify – Page Properties and then click on the Title/Encoding category on the left of the screen.
The title element is the only element which is required to be placed within the head element. In addition a number of optional meta elements may be placed in the head area to provide further information about the current page. One such meta element is generated automatically by Dreamweaver along with the title: the content-type. This declares the character encoding for the benefit of the browser and is particularly important if you have a site with an international audience. To specify the character encoding, choose Modify – Page Properties, click on the Title/Encoding category on the left of the screen and then choose an Encoding option from the drop-down menu.
The meta description element is also one of the most important since, along with the title text, it is often displayed when your page shows up in the search engine results. The description meta tag should consist of a couple of sentences summarising the content of the page. To create a description in Dreamweaver, choose Insert – HTML – Head Tags – Description then enter your description in the dialogue box which appears.
Let’s just mention one final meta element: keywords. The keywords meta element should contain a list of the important words and phrases to be found on the current page. Only text that actually appears on the page should be listed. To create the meta keywords element in Dreamweaver, choose Insert – HTML – Head Tags – Keywords.

The Remote Info tab of the Dreamweaver Site Setup dialog box allows you to supply details of the remote web server. This will be used by Dreamweaver to connect to the server hosting the site so that information can be uploaded and downloaded. For internet sites, Dreamweaver uses file transfer protocol (FTP) to connect to the server, as shown in the QuickTime example. For intranets and sites being developed on a local server, the Local/Network option is used.
For FTP host, you can enter either the host name or IP address of the FTP connection to your web server. The name usually takes the form ftp.yoursite.com or www.yoursite.com. If in doubt, consult your internet service provider (ISP).
Host Directory is the name of the directory on the web server in which internet files need to be uploaded if they are to be visible on the web. Check with you ISP to see whether files should be uploaded to the root directory or into a sub-directory.

In the next section, you need to specify the login and password which have been allocated to allow you FTP access to the server hosting your site. Note that Dreamweaver activates the save password option. If you think this is a security risk then click the checkbox to deactivate this option. Again, this information will be available from your ISP.
Firewalls are widely used by companies to block access to their intranets and to control how their own workers access the Internet. If your company uses a firewall then you must enter the relevant information in Preferences. Once you have done so, the Use Firewall option will be automatically selected. If your company uses a firewall, check with your network administrator to see whether it uses passive FTP, a system whereby the FTP connection is initiated by the client rather than the server.
The Check-in/Out feature can be used when several team members are working in collaboration on the same site. When a team member is working on a particular file, Dreamweaver will place a check mark next to the file in the remote listing in site files view as well as the name and email of the person editing the file, so other users can email him or her. If you activate this option, you must enter your name and email in the appropriate boxes.

You could say that it all started with a math problem. That problem brought on the challenge of more complex math problems. Humans were performing these complex math problems using various methods. Then came the abacus: a simple instrument designed to aid in performing mathematical calculations. One might say that this is where computer training began: the first teacher training the first student on the operation of the abacus.
Centuries later, even after other devices had been created to aid in mathematical computations, the original ‘computer’ – the abacus – remained. Through the aid of electronics came the first computer. This first computer could fill a room. In fact, there are many from that era in use to this day: they still fill a room. The purpose of the first computer was to complete complex mathematical operations in little or no time.
In the beginning, computers were the forte of scientists and mathematicians. Then they became more prevalent making their way into universities and other higher learning institutions. At the universities and other higher learning institutions sat students undergoing their first computer training classes. Students anxiously stood in line after line to sign up for computer training classes: many were turned away due to over-crowding.

Advancements in technology have meant that super computers have been continually shrinking in size. In fact, computers can now be found that are smaller than a cornflake: they are properly termed microchips or mini-computers. Along with the shrinking size of the computer came the shrinking price of a computer. Eventually, computers became affordable enough for the average Joe to own. Not only were they small and affordable, they were portable (think laptop).
As computers became more and more sophisticated, somebody needed to know how to use them. Universities offered computer training courses as well as small colleges and technical colleges. What was once considered an intellectuals pursuit only, has become commonplace. High Schools initially offered computer science’s where basic computer programming and computer basics were taught. The computer then made it’s way into middle schools and on into elementary schools. It’s come to the point where everyone attending public schooling is exposed to some form or another of computer training.
Nowadays, it’s probably true to day that young school-aged students began having more experience than the older generation. In fact, it seemed they were outpacing their elders in at least that one area of expertise.
The older generation began to recognize the need for computer training. Many were busy raising the younger generation. This generation found it difficult to take time to attend formal computer training in a classroom environment. Still others, busied by a full time job faced a similar dilemma. Computers were in the workplace and the higher paying jobs were going to those with computer knowledge or outright expertise.
Computer consultancies, institutions, and computer experts recognized this and took advantage of it. The lack of computer training and or lack of time created a niche. Computer training took off. Online computer training courses became available for just about anyone that could find their way onto the internet. This truly brought computer’s to everyone.
