There is no charge for Internet usage after your initial membership fee. DePaul University pays an annual fee for access to the Internet regardless of how heavily you use the Internet - whether you connect with someone else on campus or to an international library thousands of miles away. Visit the DePaul Online Web Page Name Identifying Each machine on the Net has a number assigned to identify it to other hosts. The numbers are in four parts, like 123.45.67.89. The only number like this that you have to worry about is your host computer number.
Most hosts also have names, which are a lot easier to remember than numbers.
The names have multiple parts separated by dots, for example, csc.depaul.edu . The numbers can be used as a secondary means of contacting another computer if the name method does not work. E-mail is by far one of the most widely used tools on the Internet. It allows different users to communicate with each other with no consideration for the distance separating them. Eudora is a full-featured mail sending and receiving program available with DePaul computers.
