Web page - Explanation and definition of web page
What is a web page
Web page is defined as an electronic document that contains textual, visual and / or audio information that is hosted on a server and can be accessed by anyone who has a connection to Internet. A web page is part of a collection of other web pages giving rise to the so called website which is identified under the name of a domain.
The creation and development of a web page is under a programming language that can be interpreted by browsers, languages like HTML, PHP, ASP, JSP or RUBY are examples among others. At the beginning of the era of Internet, on the 90´s, knowledge of a programming language for the development of a web needed, a task entrusted to people with high computer skills, today we have specialized software capable to work as a text editor, that transforms all the information inserted in a programming language that can be interpreted by browsers, thus allow a lot of people create websites with just a few computer skills, software as Dreamweaver, Amaya, Sharepoint Designer or Mozilla Composer are among others called WYSIWYG (acronym for "what you see is what you get") capable of creating complex websites with the environment of a simple text editor.
Once you have created and developed the web page is necessary to host them in a server which can be defined as a constantly connected computer to private intranet or Internet whose goal is to have the website at any time of day. To access the server is necessary to use software called FTP clients, which connect the personal computer which has developed the web page to the server where you will host, Filezilla, FileFTP or Cute FTP are other examples of FTP clients.
Finally, once hosted our website these are accessible to everybody by the use of browsers which allow display properly housed and developed information, Chrome, Mozilla, Spartan and Safari are other examples of widely used browsers.
Classification and types of Web pages
We can group or classify all the web pages into 2 groups:
Static web page
Dynamic web page
Static web pages are those whose information is not changed in a medium or short term, it is also recognized as not interact with the user or navigator, its programming language is based on HTML and are composed mostly of text and images.
Static web pages were the first type of pages that appeared during the development and expansion of the Internet, its creation and development is relatively easy only with programs styles text editors that allow us to program them without knowing any HTML, this is one of the great advantages that this type of web pages. On the other hand whenever you need to change any part of the web you need to connect to the server where it is hosted and upload the modified documents, which the inconvenient that this takes time and effort.
Dynamic websites are those that are able to interact with the user due they are connected to databases that allow the development of web applications, its main advantage is the personalization of web based user and the speed of modification of the content. Such sites are developed under programming languages like PHP, ASP, JSP or RUBY, managing these languages requires some computing knowledge.
The first dynamic web pages were created in the early 90s due to the expansion and exponential growth expansion acquired by Internet and the new needs that originated, the immense volume of information that was needed to have search engine like Google, Sales by Internet triggered the development of the first e-commerce sites like Amazon, web 2.0 finally led to the development of the first social networks like Facebook launched in 2004.
Opinion forums, social networking, online stores, search engines, emails managers or hosted business applications in the cloud, are other examples of dynamic websites.
The dynamic and static web page can be classified in turn:
Private web pages are those that can only access a limited number of people that can be identified and recognized by the system access while public are accessible by anyone with an Internet connection.
Today within the same website there are 4 kinds of web pages described above, for example access to our bank account is a dynamic page given that the available balance changes instantaneously when we make a purchase, in turn is a private page due their access is restricted to persons who can authenticate with keys or password. But within the website of our bank are static web pages with contact addresses or global information about the site and use policies turn these pages are public given that no authentication is required to access them.
