Joining committees or attending lectures about issues which already interest you are excellent starting points for networking. Talking to someone you don't know is easier when you have a common starting point. Or maybe you draw a total blank. A lot of people know the word, but don't really have any idea what it means. A network is like a web of intricate connections.
Networks consist of people who are connected by common interest.
There are many types of networks, including social, political, and professional. To network is to talk to people with whom you share common interests or services. You network when you call someone to get information. You also network when someone calls you and needs information that you can provide. It's always a good idea to have the number of a contact, or someone who has contacted you.
