Sharing an internet connection with a wireless router 

A wireless router hooks up directly to your cable or DSL modem via a cable. The wireless router will then transmit the broadband single to the computers with a wireless card in the range of the network. You will need to make sure that the cards are configured for the home network, same as with a wired network, but after that, you will be wire free!

Linksys wireless routers are an excellent brand which offers many benefits to users. Linksys makes routers which use 802.11g technology, which offers increased speed and range over older standards. They offer wireless routers in a variety of price ranges so they are affordable and functional for a wide variety of wireless networks. You can also purchase a linksys router with speed booster technology to further increase network speed and productivity.

Introduction to Web Development

Web developers and designers create the websites that makeup the Internet. These series of articles are meant to introduce web development and provide resources but not replace the benefits of taking a course through one of your local education centres.

The previous page is an example of what can happen to a website if to proper steps are not followed?

At a very basic level the Internet is one computer connected to another computer through a phone line, cable or wireless signal; communicating with each other. Add to this the ability to connect to any other computer and communicate with it in fractions of a second and you have the Internet in a nutshell. The terms 'net' or 'web' are a way of visualizing this interconnectedness.

Basic Concepts

When working on a website there are a couple of key concepts that need to be understood.

The local computer is the one you work on to develop your website. The remote computer or server is the one that contains website and serves up the web pages to your visitors. For security reasons servers require you to log on before you can work on them.

Always consider the file on the server to be the original copy as this is the one that visitors will see. If you need to make changes to a existing web page retrieve a copy of the original from the website first. If more than one person is updating the website this will avoid overwriting someone else's changes. This also allows you to test the new page(s) beforepublishing it to the website.

Hypertext Markup Language or HTML is the language that is at the core of all document on the Internet. It was created by Tim Berners-Lee. The language has evolved to work with the largerXML language. Extensible Hypertext Markup Language (XHTML) allows developers to build websites that take advantage of this broader language. An HTML or XHTML document is a text document with instructions for browsers on how to display the web page (Note: HTML and XHTML are used interchangeably through these documents). Hyperlinks tie all the documents together to integrating the website and connecting it to the rest of the "Net".

Protocols

Around the mid 90's with the introduction of HTML and graphic capable browsers the Internet has taken off as a major communication tool accessible to vast numbers of people. As there is no one organization that owns the Internet there are a number of protocols that have been established to make this communication work. These protocols are overseen by the World Wide Web Consortium or the W3C.org. As of January 2000 the W3C recommends that HTML documents should comply to XHTML 1.0 standards. Visit www.w3c.org for more information on this and many more Internet protocols and standards.

The protocol that connects the computers together and directs the transfer of information has stabilized on Transmission Control Protocol/Internet Protocol (TCP/IP). Error correction is built into this protocol so you can be fairly confident that visitors are seeing the website as it was meant to be viewed.

The three main graphic media formats are Graphic Interchange Format (.GIF), Joint Photographic Experts Group (.JPG) and Portable Network Graphic (.PNG).

There are many sound media format though MPEG 1 Audio Layer 3 (..MP3) and Window Audio (.WAV) are currently the most popular. Musical Instrument Digital Interface (.MID) format is a way of storing complete songs in relatively small files though not as popular with the advent of high speed internet connections.

The standards around video and animation media are less straight forward.

Streaming technology allows content providers to send information such as audio and video media in a controlled stream rather than as a complete file. There are number of companies that provide software to create and play multimedia including; Abode Flash, AOL Real Audio, Microsoft Media Player and Apple Quicktime.

Simple animations can be created using the GIF format. The Moving Picture Expert Group (.MPEG) format is also a video/audio format.

A player is required to play multimedia format. Most browsers have plugins that can be downloaded for free.

Separating Layout and Design

HTML is used to layout the document using the tag structure and styles are used to create the design. For example use tags to define a paragraph but use a style to indent and change the colour of the text in the paragraph.

Role of the Webmaster

The Webmasters role is to oversee the entire website whether they are maintaining the entire site themselves or the site is being maintained by various other people. Their role is to keep the site consistent with company or organizational policy, ensure that the site is working properly (i.e. links work, graphics display etc...) and answer questions that are generated from the website. In smaller organizations most often the Webmaster is also the Web Developer. Even if the Webmaster isn't involved in the day to day site maintenance the person taking on this role must have a good understanding of HTML.

Role of the Web Developer

The Web Developer's role is to layout, markup and develop the web content. Their strengths are a strong understanding of HTML and a grounding in web server technology. Though a developer will often use a HTML editor or publisher, the core language of the Internet is HTML and that design tool is simply interpreting the hypertext markup language for the developer. If the developer doesn't understand HTML they will, very quickly, find themselves in a crisis.

Another skill that is not always required but good to have is an understanding of aprogramming or scripting language. Developers usually use cascading style sheets (CSS) to create complex site-wide formatting of documents and to create dynamic HTML documents. Adding and modifying JavaScript is also a common required task. Many sites also incorporate programs based on a variety of different languages such as Perl, PHP, ASP, etc. Many website use databases for various functions including updating information, displaying user specific data, submitting queries and tracking transactions as well as many other functions. Knowledge of a range of Simple Query Language (SQL) languages may also be necesssary.

Role of the Web Designer

A design's skills are geared to graphicals design and visual content. Their job is to create the visual imagery for the site. A background in graphic design and a sense of style are required skills. A designer must also understand HTML and CSS to be able to use these languages when formatting a document.

HTML and/or Publishers

As mentioned it is important that the designer have a strong basis in HTML. That being said much of the design work done today is created in a web design software application. Web design software has improved over the years to become a useful and even a required tool of a designer.

There are many commercial programs available. Microsoft's Frontpage and Macromedia's Dreamweaver are two examples.

Mozilla Composer is a free yet versitile web page editor. It takes a bit of practice to understand the quirks of the software but it is a very useful tool.

As well as commercial products there are many shareware software packages that range from HTML text editors to complete GUI applications.

Regardless of the development tools that you use you will find that you are constantly referring back to your favorite text editor. Microsoft's Wordpad or Apple's TextEdit (SimpleText) are free options but a good text editor is worth the cost. Which ever application you use be sure to save all HTML documents as a text file.

Internet

The Internet or the Net is a collection of computers, all linked together, to share information globally. It was first developed in the U.S. by two universities who were both working on the same contract and wanted to share their data. They were faxing information back and forth and then retyping it until they came up with a piece of software called Unix to Unix Copy Program or UUCP.

The Internet was born and has mushroomed outward from that point.

There are 4 things that are necessary to "get on the net" with a full graphic interface (picture, sounds, animation, etc...).

• A computer - preferably with a fast processor and lots of memory (64 Mb or more)
• A modem - preferably 56,000 baud or high speed digital
• Browser Software - often installed with your operating system or can bedownloaded off the Internet
• An ISP - An Internet Service Provider is a service that connects your home or office computer to the Internet

Once you have purchased an account with an ISP you will be given an account name. This is often your email address as well. You will also be given a passwordand should also be provided with instructions on how to change the password to a unique and personalized. The generic password provided with your account should be change to one of your own. Protect your password as you would any personal identification number (PIN) number.

top

The ISP will also provide information on how to configure your software. This can be simple or difficult depending on your Operating System. Once configured you simply run the software to connect your computer's modem to the ISP's modem, giving you access to the Internet.

There are a number of pieces of software that work together to connect you to the Internet.

top

The first and most complicated is the dialer or socket software. This is the software that makes the physical connection with the ISP's computer and the internet. This needs to be configured only once but you will need instructions from your ISP on how to do this as each ISP has a different setup.

top

The second piece is an Internet browser. This is the program that locates websites for you and allows users to maneuver around (surf) the World Wide Weband view web pages. Some of the more popular browsers are Mozilla Firefox and Microsoft's Internet Explorer.  Mosaic was the first browser and most modern browsers still use the basic model that the first browser used. Some other browser are Opera, Safari, Netscape as well as dozens of others. Before graphic browsers Lynx  was the most popular browser and is still available for text browsing. New browser are being developed and current browsers are constantly updating their programs. It is extremely important to update your browser every once in a while. Some ISP have a proprietary type of browser though most have given up this practice as it limits the users abilities to browse the Internet.

Type the url or web address of the website that you want to visit in the address bar of your browser and press Enter or click Go. Collect your favorite websites by adding them to your Favorites or Bookmarks. To go to a Favorite or Bookmark, click on the menu and click on the link.

Another piece of software is an email program   . This program controls sending, composing and receiving email. Most email programs can also be used to read postings on newsgroups.

Instructions for getting this software can be obtained from your ISP though you may have to download the newest version yourself.

top

There are many different ISPs. If you attend a university or college or belong to a military or government organization you can most likely get Internet accessthrough your school or work. If not you will most likely buy access from acommercial provider.

Another option, if you are in a major center, is the Freenet. Many major cities have groups devoted to making the Internet accessible to the greater majority of people and create Freenets which allowing members free access to the Internet. They run on private and public donations. It is an excellent way of learning about the Internet in a helpful environment.

Once you are connected you will have access to Email, Newsgroups, the World Wide Web (WWW), File Transfer Protocol (ftp), Internet Relay Chat (irc),Search Engines, ICQ and other Internet Services.

Backing up Files

Computer errors and software failures happen ocasionally so it is important to backup your files and documents.

One simple way to backup your files is to copy them to a disk. If there are only a few small files a floppy disk will work but if you are backing up lots of large files a cd/dvd burner, a second hard drive or tape backup may be needed. You can use a software program to automate backups or do it manually. A manual backup usually involves dragging the files or folders to the backup disk or tape to create the duplicate backup.

Store your backup files in a safe place out of the sun and away from electro-magnetic devices such as speakers and wires with strong electrical currents.

Every file that you create and plan to keep should be backed up. This includes word processing documents, financial information, databases, photos, etc...

Some less obvious files that also need to be backed up are email, Internet Favorites or Bookmarks, and Address Books. Check the help files in your email program on how to back up email. Generally each folder name in your email program is a file containing the individual email messages and copying these files to the backup disk or tape will be sufficient. Software preferences such as customized menus and settings can also be backed up. Check your software's help files to find out where these files are located.

A newer software version may be installed on the computer before ever needing the backups so make sure that the newer programs can handle the older file format.

When to backup is an individual choice. A company should have a backup policy which explains how and when data should be backed up. It all depends on how important the information is and how difficult it would be to duplicate it in the event of a system failure. If the information is critical an automatic backup system that duplicates the documents immediately may be needed (a Redundant Arrays of Inexpensive Disks (RAID) system is an example). If the files are not critical a weekly backup may be all that is needed. It is impossible to determine when a system failure will occur so it is better be cautious.

The backed up data can then be used as an archive, to recover from a system failure or to transfer data to a new computer system. Simply copy the files to the correct folder to restore them. Backup software will have an automatic recovery feature that will restore the backed up file automatically.

Compression and Decompression

Most software you buy or get off the Internet is Compressed. Computers store information in bytes which are made up of on or off signals. The software applications that uses these files need to have all the on and off signals (bytes) in place but when the file is stored they can be modified to take up less space on the storage disk or tape.

There are commercial and shareware programs that will compress and decompressed files for you. The most popular form of data compression is calledzip or stuffit but there are others available as well.

Programs are also available to compress and decompress your files as you or the application you are using requires them. This can be a way of making more space available on a hard drive. Windows comes with a program that will compress part of your hard disk. Be sure to read the documentation before embarking on a project like compressing a hard drive.
