Distance learning comes in different mediums. Some of the various technologies used to facilitate distant communications and learning are summarized below. Remember that some classes may employ a combination of two or more of these technologies.

Online classes use computer networks for communication and information exchange. The largest computer network is, of course , the Internet, so an online course usually requires Internet access. There are many types of online communication possible - it can be as simple as e-mail or as elaborate as streamed video and audio. The most basic online courses will make use of the World Wide Web and e-mail. |

The ND Interactive Video Network (IVN) is a high quality compressed digital videoconference system. All IVN rooms are equipped with video cameras, TV monitors, microphones and other specialized telecommunication equipment to transmit live audio and video over leased T1 telephone lines. This connection provides a two-way audio and two-way video connection. |
|
Classes are transmitted in a fashion similar to regular TV broadcasts, except orbiting satellites relay the signal instead of land-based antennas. Specialized receiving equipment ( dish antenna and associated electronics) is required to view the signal. Therefore, satellite courses are usually received at a host site, typically a school. |
|
A VCR and TV are required to view the class materials. Course lectures are presented on standard VHS videotapes. Since videotape is a one- way medium, these classes usually use another form of communication in conjunction with the tapes, typically correspondence or online. |
|
Students will study and learn independently under the guidance of a university professor. All the communication between you and the professor is accomplished through the mail or by fax. If you need help, you can use the telephone or arrange for an appointment. |
|
The Educational Telephone Network (ETN) includes a conference bridge which connects several locations via standard telephone lines for an interactive credit class, discussion or educational presentation. ETN can also interface with the Medstar Satellite Network to provide interactive return audio from receiving sites. |
|
Online Dakota Information Network (ODIN) provides a computer-based library catalog for the NDUS libraries. There are currently 49 libraries that are ODIN members. Additionally , ODIN is part of a regional network linking Minnesota and South Dakota. |
|
Courses may be offered off campus but in a face-to-face medium. This means the course is being offered in-person at a site other than the home campus. Both the instructor and the students will be located at a designated site away from the campus. |
