A professional network service (or, in an Internet context, simply professional network) is a type of social network service that is focused solely on interactions and relationships of a business nature rather than including personal, nonbusiness interactions. By using a professional network service, businesses are able to keep all of their networks up-to-date, in order, and help figure out the best way to efficiently get in touch with each of them. A service that can do all that helps relieve some of the stress when trying to get things done.
