Chapter 1 Web Basics and Overview
Chapter 1 Web Basics and Overview The Web is an Internet-based distributed information system. Anyone with a computer connected to the Internet can easily retrieve information by giving a Web address or by simply clicking a mouse button. The Web is a great way to disseminate information and making it available 24/7. Information can also be collected from Web users and customers through online forms. Maintainers and administrators can control and update Web content from anywhere on the Web. All these make the Web a powerful tool for mass communication, e-business and e-commerce. Compared with TV, radio, news papers, and magazines, putting the word out on the Web is relatively simple and inexpensive. But a website is much more than such one-way communication media. It can be a virtual o±ce or store that is always open and supported by workers from anywhere. Web service companies o®er free Web space and tools to generate simple personal or even business Web pages. But, well-designed and professionally implemented websites are much more involved. Even then, expertly produced websites are still much more cost-e®ective than other means of mass communication. For business and commerce, the cost of a website is negligible when compared to building and operating a brick-and-mortar o±ce or store. Once in-place, a website is a store that never closes and that is very attractive. People take great pains in building an o±ce or store to project the right image and to serve the needs 7 8 CHAPTER 1. -
