Traditional commerce perhaps started before recorded history when our ancestors first decided to specialist their everyday actively.

Instead of each family unit having to grow crops, search for food, and make tools, families developed skills in one of these areas and traded some of their production for other needs. It started with bartering, which eventually gave way to the use of currency, making transactions easier to settle. However, the basic mechanisms of trade were the same.Some body rated a product or provided a service, which somebody else found valuable, and therefore was willing to 'pay' for it in exchange. Thus, commerce, or doing business, is a negotiated exchange of valuable products or services between at least two parties and includes all activities that each of the parties undertakes to complete the commercial transaction. Any commercial transaction can be examined from either the buyer's or the seller's viewpoint.

One of the most utilized of these Internet applications is the World Wide Web.What sets the Web apart is an easy-to-use interface to a complex network of computers and data.

WWW Basics: Browsers A browser is an application which provides a window to the Web. All browsers are signed to display the pages of information located at Web sites around the world. The most popular browsers on the market today include Microsoft's Internet Explorer and Netscape Navigator. Web Sites Information on the Web is displayed in pages.

New Roles for E-commerce These integration efforts are likely to continue in the future. "You're getting to the point where consumers are more and more expecting Web sites to help them do their retail buying," Gartering research director David Cheer told the E-commerce Times. "They may not necessarily be looking for the click to order, but they're looking for store-locator information, to help plan a project.

Also, more companies will start to offer post-product support that, in effect, serves as brand enhancement for the next sale. Through all of these tactics, the Web will become an integral part of the 360 degrees of the sales cycle," Cheer said. And as businesses increasingly embrace e-commerce, consumers' level of comfort and familiarity with online transactions also will keep rising steadily. With more consumers turning to the Internet to shop and interact with the same brands they see in the real world, the importance of the online channel will keep growing.This growth should prompt even more retailers to set up shop on the Web, perpetuating a cycle that will boost e- commerce revenue to record levels again and again in coming years.

Packet Switched Networks: A packet-switched network is a digital communications network that groups all transmitted data, irrespective of content, type, or structure into suitably sized blocks, called packets. The network over which packets are transmitted is a shared network which routes each packet independently from all others and allocates transmission resources as needed.The principal goals of packet switching are to optimize utilization of available link capacity, minimize response times and increase the robustness of communication. When traversing network adapters, switches and other outwork nodes, packets are buffered and queued, resulting in variable delay and throughput, depending on the traffic load in the network.
