Fourth Week in Computer

I learned what are the different types of websites.


    Static Website

A static website is the simplest form of website, in which the site’s content is delivered without the use of server side processing. Static websites are used principally for brochure sites and can include complex graphics, animations and JavaScript driven features.

The main limitation of static websites is that they cannot provide complex user interactivity because they cannot either gather information from the user or serve content which is dependent on user actions. Large static sites are also time consuming to develop and more difficult to update because changes need to be implemented individually on each page of the site. However, if a business does not require a large website or advanced interactivity, a static site which is developed using XHTML and CSS will provide clean, compact coding and good search engine performance.

Dynamic Websites

Dynamic websites rely on server side scripting to provided advanced interactivity and usually use a database to deliver the content for individual pages. A dynamic approach is appropriate for developing large websites with content which is formulaic, for example, catalogues, photograph albums and complex series of data. A dynamic website will be required to allow users to sort and search records, or to restrict access to parts of the website using a log-in procedure.

Generating website pages on the fly, using a database to store and deliver content, is an efficient way of managing a large site, with maintenance and updating generally much easier than for a comparable static site. The disadvantage of dynamic websites is that Search Engine Optimisation (SEO) techniques are more difficult to implement, particularly if the site’s SEO needs are not taken into account at the development stage.

Content Managed Website 

A content managed website is a further refinement of the database driven dynamic site. The content management system provides a password protected interface through which users can add, edit and remove content from the site. A content management system is particularly useful in the case of large sites which have numerous contributors, some of whom may be working from remote locations.

eCommerce website

An eCommerce website is a dynamic website which has the functionality to process financial transactions. Most eCommerce websites are built to mimic a bricks and mortar store and use the model of stock pages, shopping basket system and checkout, using a secure online payment system. Many eCommerce sites also include a content management system, so that product details can be added or updated, and some include advanced features such as automated stock control.

Flash Websites

Flash is proprietary software developed by Macromedia which is used to generate complex animations. The programme is sophisticated enough for entire websites to be constructed using Flash technology. Flash websites can be visually stunning and provide otherwise unachievable levels of user interactivity. However, it is almost impossible to carry out any meaningful form of SEO on a Flash site and so it should, generally, be avoided.

Second Week in Computer

I learned what is meta tag.Metadata is information about data.

The <meta> tag provides metadata about the HTML document. Metadata will not be displayed on the page, but will be machine parsable.

Meta elements are typically used to specify page description, keywords, author of the document, last modified, and other metadata.

The <meta> tag always goes inside the head element.

The metadata can be used by browsers (how to display content or reload page), search engines (keywords), or other web services.

First Week in Computer

I learned what is HTML, which stands for HyperText Markup Language, is the predominant markup language for web pages. HTML is the basic building-blocks of webpages.

HTML is written in the form of HTML elements consisting of tags, enclosed in angle brackets(like <html>), within the web page content. HTML tags normally come in pairs like <h1> and </h1>. The first tag in a pair is the start tag, the second tag is the end tag (they are also calledopening tags and closing tags). In between these tags web designers can add text, tables, images, etc..

The purpose of a web browser is to read HTML documents and compose them into visual or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page.

HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts in languages such as JavaScript which affect the behavior of HTML webpages.

Web browsers can also refer to Cascading Style Sheets (CSS) to define the appearance and layout of text and other material. The W3C, maintainer of both the HTML and the CSS standards, encourages the use of CSS over explicitly presentational HTML markup.
