Chapter Web Publishing Issues
Introduction Web Publishing • Web publishing, or "online publishing, " is the process of publishing content on the Internet. • It includes creating and uploading websites, updating Web. Pages, and posting blogs online. The published content may include text, images, videos, and other types of media. • In order to publish content on the web, you need three things: 1. web development software. 2. an Internet connection. 3. a web server.
Web Publishing Web development software. • Notepad • Dreamweaver • Artisteer

One of the greatest advantages of wireless Internet connections is the “always-on” connection that can be accessed from any location that falls within network coverage. Wireless connections are made possible through the use of a modem, which picks up Internet signals and sends them to other devices. Dial-Up • Dial-up connections require users to link their phone line to a computer in order to access the Internet. This particular type of connection—also referred to as analog—does not permit users to make or receive phone calls through their home phone service while using the Internet.
>>Continue : Web Publishing Internet connection. Broadband • This high-speed Internet connection is provided through either cable or telephone companies. One of the fastest options available, broadband Internet uses multiple data channels to send large quantities of information. The term broadband is shorthand for broad bandwidth. Broadband Internet connections such as DSL and cable are considered high-bandwidth connections. • DSL, which stands for Digital Subscriber Line, uses existing 2 -wire copper telephone line connected to one’s home so service is delivered at the same time as landline telephone service. Customers can still place calls while surfing the Internet.
>>Continue : Web Publishing Web Server • Web servers are computers that deliver (serves up) Web pages. • Every Web server has an IP address and possibly a domain name. For example, if you enter the URL http: //www. pcwebopedia. com/index. html in your browser, this sends a request to the Web server whose domain name is pcwebopedia. com. The server then fetches the page named index. html and sends it to your browser.

>>Continue : Technical Issues Site Design, building and maintenance • Two main options for publishing a web page are flat HTML or a CMS.
>>Continue : Technical Issues Design Considerations • Sites don't work like books. Most movement comes by means of web indexes, implying that clients can sidestep your landing page. That makes site configuration and route essential. • Key ideas to remember when planning your site are a. Straightforwardness b. Consistency c. Appropriate d. Ease of use.
>>Continue : Technical Issues Understand the medium • Readers experience web pages in two ways: by reading pages online or by downloading information into text files and perhaps printing it out. • Keep documents likely to be read online short. • Carefully tune the graphics to the bandwidth available to your audience. • Documents likely to be printed and read off-line should appear on one page, which should be narrow enough to print easily on standard-size paper.
>>Continue : Technical Issues Simplicity • • • Keep design elements to a minimum. Minimize clutter to make the document simple to use. Use only one or two fonts and a minimum of three heading sizes. Avoid piling up special effects (bold, italics, blinking and so on). The Web offers great possibilities for using color, moving images and sound files, but keep things simple and elegant, and do not overcrowd the screen.
>>Continue : Technical Issues Graphic Embellishments • Use horizontal rules, graphic bullets, icons and other visual markers sparingly (if at all). • The tools of graphic emphasis are powerful and should be used only in small doses if you want to avoid a garish, confusing clown's pants effect. • Keep the design elements and content appropriate to the situation. • Determine the image or mood you want to convey through your website and stick with it. • Use appropriate graphics to communicate rather than just decorate.
>>Continue : Technical Issues Consistency/predictability • Repeat major design elements (headings, text blocks, graphics, navigational controls, etc. ) to match users' expectations. • Create a template or format that provides a consistent pattern for the user. Establish a consistent background that is maintained throughout the different levels of your site.
>>Continue : Technical Issues Flexibility • Unlike a book, where the layout is literally fixed to the page, the Web is dynamic. • Users can increase or decrease font sizes and turn images on or off. • Users' screen resolutions can range from 600 x 800 to 1600 x 1024. When designing your site, remember that users can experience your site in a number of ways.
>>Continue : Technical Issues File optimization • Images, sound, video and PDF files can exist in a range of formats and resolutions. A twominute video clip, for example, could be provided to users as an avi file 100 Mb in size at one extreme or a 2 Mb MPEG file at the other. Both offer similar screen resolution and image clarity. • What is the best screen resolution for video files? High resolution (800 x 600 pixels) is too much and will result in a large file download; 250 x 200 pixels may be perfectly adequate. The same considerations apply to moving images and sound files. REMEMBER: the higher the resolution of the image, the larger the file size. • Accordingly, irrespective of format used, 72 DPI (dots per inch) will be more than adequate for images to be used on the Web.
>>Continue : Technical Issues File Backup • If you are building or maintaining a site yourself, remember to back it up frequently and to make a back-up copy before overwriting any file. That way, if things go wrong you can reinstall the original file.
Bandwidth • Bandwidth is like lanes on a highway. It allows for more traffic to go through at once, while still retaining high speeds. Common activities causing bandwidth problems are: • Watching videos from Internet (You. Tube, Netflix) • Large file transfers between computers (greater than 100 megabytes in size) • Constant stream of data (surveillance footage from security cameras) • Downloading files from internet • Uploading file to the internet. Large file transfers or data streams within a network should be placed on a separate network, in order to avoid bottlenecking other users.
Browser differences • Web browser is a translation device. It takes a document written in the HTML language and translates it into a formatted Web page. • The basic rules for translating HTML documents are established by the World Wide Web consortium, which publishes the official HTML standards. • But there's considerable room for interpretation within those ground rules. • Since HTML tags isn't universal, developer could building page parts using the language that not all browsers understand. In that case the browser will ignore that part page it can't translate, and the way page displays will be affected. • Test your pages with HTML Toolbox and review its Browser Compatibility report.
>>Continue : Browser differences Why do you care about Browser Compatibility? • Web sites reflect the company's professional image. If your site renders improperly or not at all, your company's reputation can be tarnished. If your site has browser display problems, visitors and potential customers will leave your site and not look back. • In contrast, a professional looking site will make visitors feel more comfortable, stay longer and browse more pages. And because of this increased credibility, they are more likely to purchase the products and services that they are looking for from you.
Monitor Resolution • Also called as screen resolution. • Screen resolutions begin at 320 px wide all go the way to thousands of pixels wide. • So, because of all these variants it is worth making sure that your site works in as many of them as possible.
>>Continue : Monitor Resolution There are three ways to get round the problem of screen resolution: • Make your content dynamic so that is adjusts to meet the browser resolution. The modern way to do this is with a responsive layout. • Make the site ‘full width’ to that it will always fill the screen. Which is fine if everybody has the same screen as you. But just because it looks good on your 1024 pixel wide screen doesn’t mean it will work for somebody with a 21″ monitor at 2048 pixel resolution. • Put your contents in a box that will fit most screen resolutions. Box width generally accepted minimum resolution for a PC/MAC these days is 1024 px, setting a content width of 960 px should be OK. Use your analytics package however to check before you make any major changes. • If most of the visitors use a smartphone or a tablet then you need to cater for them as well by using responsive design.
