Define the Internet, Intranet and E-Commerce. Discuss the advantage of E-commerce over conventional business. Briefly describe the different generation of E-business.
INTERNET
The Internet is a new world. The Internet is not only "The Big Picture," it also offers a global perspective. By providing connectivity to anyone with a computer and a telephone line, the Internet is the networking breakthrough of our lifetime. It includes everything from universal e-mail to transactions between individuals and between companies. Of course, this now includes commerce as well as information exchanges and new directories (such as search engines) that provide phone book-style accessibility for digital communications.Some of the most important results of this networkingrevolution are new forms of marketing and outreach, new connections between customers and collaborators, new sources for news and research, and opportunities for new kinds of distribution of products (as well as of information). But because the Internet is the broadest information super-highway, it lacks some of the security and privacy that's needed for the internal workings of business organizations. Advanced features like multimedia are also more likely to be limited because most individuals are still using dial-up connections and, as a result, have very limited data bandwidth.
INTRANETS
Intranets are new kinds of internal networks. Think of "Intra" as it is used in Intramural sports. Intranets tend to resemble the architecture of a closed-circuit video network as opposed to the Internet which is more like broadcasting in terms of its reach. Intranets are used for more private communications, connectivity among work groups and larger organizations. For example, some companies use Intranets to offer corporate services such as benefits programs and other kinds of corporate communications. Also, Intranets enable information sharing that empowers employees who might otherwise be left "out of the loop." (See "Groupware" below.) Because of their limited geographic range, Intranets offer more bandwidth, frequently Ethernet's 10Kbps or better. As a result of this bandwidth and the "closed loop" structure, more advanced networking features such as video and multimedia, as well as more technological control, are possible. For example, a company can specify that a specific web browser and even a specific version of that browser (licensed by the company) be used on its network. This enables a consistent and more dependable user experience than is possible on the Internet. Even Internet related services such as Pointcast can be customized for a particular company and its Intranet.
