The Basics of Web Development
The World Wide Web, also commonly referred to as the Web, is a collection of information systems that are interconnected by links, and can be accessed over the Internet. This collection of systems allows users from around the world to locate information on the Internet or to send electronic mail. Many people access the Web for business purposes. The Internet offers an extensive range of opportunities to advertise products and services and to make connections with customers.
Prior to the World Wide Web (WWW), there were two networks that had specific service domains. These domains included first-world wide web servers and local area network (LAN) servers. The Internet has evolved into a comprehensive system that includes national, regional, global, and international connections.
The first web server was the National Standards Association (USAS). The USAS was formed in response to the needs of network managers who were faced with managing large collections of data in a reliable and efficient manner. The association resolved that a uniform standard be developed for the management of information in this environment. The Uniform Resource Locator (URL) is the model that is used to determine locations on the Internet. A number of USAS member organizations developed and governed the W3C specification model, which became known as Hypertext Transfer Protocol (HTML).
Websites run on a web server. The web server contains programs that run on the web server and send data to and from the websites that depend on it. A web server can either be a computer system or a network of machines. A web server can serve static files such as web pages, or it can serve dynamic information, such as web applications or web pages that change frequently. A web application is a piece of software designed to display web-pages in a graphical user interface (GUI) format.
