B2B(Business to Business)Internet-based business-to-business (B2B) e-commerce is conducted through industry-sponsored marketplaces and through private exchanges set up by large companies for their suppliers and customers. Of course, companies also sell to business customers through their own Web sites.
Business-to-business (B2B) e-commerce is significantly different from business-to-consumer (B2C) e-commerce. While B2C merchants sell on a first-come, first-served basis, most B2B commerce is done through negotiated contracts that allow the seller to anticipate and plan for how much the buyer will purchase. In some cases B2B is not so much a matter of generating revenue as it is a matter of making connections with business partners.
B2C(Business to Consumer)B2C (Business-to-Consumer) is basically a concept of online marketing and distributing of products and services over the Internet. It is a natural progression for many retailers or marketer who sells directly to the consumer. The general idea is, if you could reach more customers, service them better, make more sales while spending less to do it, that would the formula of success for implementing a B2C e-commerce infrastructure.
For the consumer, it is relatively easy to appreciate the importance of e-commerce. Why waste time fighting the very real crowds in supermarkets, when, from the comfort of home, one can shop on-line at any time in virtual Internet shopping malls, and have the goods delivered home directly
C2C(Consumer to Consumer) C2C (Consumer to Consumer)E-Commerce has also emerged that allows unknown, un-trusted parties to sell goods and services to one-another. An excellent example of this is found at Ebay, where consumers sell their goods and services to other consumers. To accommodate this activity, several technologies have emerged. Firstly, Ebay allows all sellers and buyers to rate one another. In this manner, future prospective purchasers may see that a particular seller has sold to more than 2,000 customers - all of whom rate the seller as excellent. In another example, a prospective purchaser may see a seller who has previously sold only 4 times and all 4 rate the seller poorly. This type of information is helpful. Another technology that has emerged to support C2C activities is that of the payment intermediary. Pay Pal is a good example of this. Instead of purchasing items directly from an unknown, un-trusted seller, the buyer can instead send the money to Pay Pal. From there, Pay Pal notifies the seller that they will hold the money for them until the goods have been shipped and accepted by the buyer.
A type of network setup where each of the computers and network devices are interconnected with one another, allowing for most transmissions to be distributed, even if one of the connections go down. This type of topology is not commonly used for most computer networks as it is difficult and expensive to have redundant connection to every computer. However, this type of topology is commonly used for wireless networks. Below is a visual example of a simple computer setup on a network using a mesh topology.
