A business network can be defined as a group of people that have some kind of commercial relationship. It could be a boss-employee, buyer-supplier, colleague-colleague, etc.

An interesting approach is the one used by LinkedIn and ReferNet, which using the Internet can connect people with more than 1 degree of separation.

According to the experts, networking works best when you offer to help someone else with a connect, rather than asking for yourself. Business networking can take place outside of traditional business functions. Places such as airports, restaurants, even while in a movie line, provide opportunities to make new business contacts.
