""E-business (electronic business), derived from such terms as "e-mail" and "e-commerce," is the conduct of business on the internet, not only buying and selling but also servicing customers and collaborating with business partners."

The term E-business is often used synonymously with e-commerce, but e-business is more of an umbrella term for having a presence on the web. An e-business site may be very comprehensive and offer more than just selling its products and services. For example, it may feature a general search facility or the ability to track shipments or have threaded discussions. In such cases, e-commerce is only the order processing component of the site.

Today, many corporations are rethinking their businesses in terms of the internet and its capabilities. Companies are using the web to buy parts and supplies from other companies, to collaborate on sales promotions, and to do joint research. Exploiting the convenience, availability, and global reach of the internet, many companies, both large and small have already discovered how to use the internet successfully using e-business."
