Of CGI & Java Scripts

CGI and Java Scripts are both functional with both Netscape and Internet Explorer browsers. But there is an essential difference between the two. Java functions as a code executed and downloaded in the clients' side while CGI operates with the server. Before probing deeper into the difference of the two, let us first try to understand these two often-used scripts.

JavaScript requires no special plug-ins, and it works transparently within an HTML page. It animates web page graphics, allows users to change page elements (background color, display preferences), and allows site navigation. Usually, Java Scripts are made up of two parts: the JavaScript functions (the instructions for what the JavaScript does on the page) and elements that cause the JavaScript functions to execute. These two go in different ways. The JavaScript functions are placed between special JavaScript tags within the head tags in the HTML source. Java Scripts follow specific punctuation conventions. Usually, JavaScript functions are the last element within the head tag. The elements that cause the JavaScript to execute are placed within the body tags of the HTML source, depending on where the web page designer wants the JavaScript to run. Because JavaScript is included in the other HTML tags in the page source, a web page with JavaScript elements will be saved in exactly the same format as a web page: the file type should be an ASCII text, and the file name should have the suffix .html appended to the end of it. The script's difference from CGI will not be clear unless we discuss both CGI and Java Scripts.

CGI is the short version of Common Gateway Interface. It is commonly used in web pages because it allows interactivity by letting the web server respond to user input through a web page with CGI elements. A common example of CGI function is a web guest book. A web designer usually includes a web guest book in the web page so users and visitors can put in their suggestions. These suggestions are collected by the CGI and e-mailed to the designer. CGI and Java Scripts also have a similarity. Like in a JavaScript, files used in CGI must be ASCII text with the suffix .html appended to the end of it. However, if a CGI script will be stored in the CGI bin, it is most likely that the file must be saved as a Perl document. Unlike JavaScript, where the functions must reside within the head tags, form elements can be placed wherever the web page designer wants to put them. The only consideration is that to call the CGI script, HTML tags should come before the form elements of the page.

Though both scripts have different functions, both CGI and Java Scripts have undoubtedly improve the way the internet works. They have also infiltrated the world of movies and televisions with digital films and fantastic characters. Who knows, maybe

Website Development: An Introduction

Website development pertains to the whole gamut of processes and activities in regards to the development of web sites. Website development includes e-commerce businesses, web content development, optimization and web server configuration. Website development is among the prime and most lucrative businesses today. Well website development simply means the building of websites through written content and setup. It can vary from that of the static single page text websites to the most creative and complex applications like online games or social network services, example facebook.

With the increasing significance of the internet as an instrument of entertainment, knowledge and interaction, various businesses are trying to tap into its popularity. Almost all organizations have there own website, well even stars (Hollywood or otherwise) have their twitter or personal website. Websites are the simplest and most easily accessible mechanisms of reaching to various individuals from all parts of the world. With just one click, a whole new world opens up for the internet surfer.

Website development is a highly complex and equally challenging endeavor. It takes a team of knowledgeable web developers to produce a hit website. We can say that anyone can make his or her own website. All one needs is some little twitching of pictures, posting of notes. But to get the best of the domain and site, web developers should consist of the webmaster, graphic designers, IT technicians and content writers. Collaboration between and among the various professionals is necessary for true website development.

Website development can be classified into different areas. There is the client side coding, server side coding, combination, and those that utilize database technology. Client side coding pertains to one area of website development wherein the programs are executed by the client or the user's web browser. Examples of client side coding are AJAX, Javascript, among others. This means that the output, i.e. what the users see on online may differ from person to person. In server side coding, on the other hand, any request of the user is fulfilled through a script that is directly on the web server. Basically, client side coding is on layout and design, while server side coding is on back end systems. Aside from scripting and coding, web developers also perform differing roles which include web designing, copywriting and copyediting, search optimization and project management.

Website development is considered to be one of the fastest growing industries in the world. This phenomenon can be attributed to the significant decrease in cost and increasing demand for website development from many small and large businesses. The expected cost of website is a variable considering the complexity and the content of the site. The more applications and choices available, the more pricey it is.
