Your telecommunications account allows you to access an almost inconceivable amount and variety of online information. In mid-1994, for example, there were more than 2 million hosts (computers with unique addresses that allow users access to online services) on the Internet, and between 20 and 30 million people in 146 countries who could exchange electronic mail with each other (Calcari, 1994; Quarterman, 1994). Within this vast array of possible connections, there are basically two ways that information can be shared online: among people and between people and remotely-located machines.
