| Gender Changer | A gender changer is a cable adapter that converts a male connector into a female connector of the same type, or a female connector to a male connector of the same type. A gender changer can be a self-contained, rigid piece of hardware, or it can consist of a short length of cable with male connectors on each end or female connectors on each end. Sometimes the term is used in reference to a device that has a male or female connector at each end, but the two connectors are of different types (for example, a female USB connector on one end and a female serial port connector on the other). |
| Geocaching | Geocaching, also referred to as a global positioning or GPS stash hunt, is a recreational activity in which someone "buries" something for others to try to find using a Global Positioning System (GPS) receiver. The pursuit can be thought of as a GPS-enabled treasure hunt. Usually, a geocache consists of a small, waterproof container that holds a logbook and inexpensive trinkets. Participants are called geocachers. |
Glyph
| graphic symbol that provides the appearance or form of a character (alphabetic or numeric or form for a character).
|
| Grid Computing | Grid computing (or the use of a computational grid) is applying the resources of many computers in a network to a single problem at the same time - usually to a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data. A well-known example of grid computing in the public domain is the ongoing SETI (Search for Extraterrestrial Intelligence) @Home project in which thousands of people are sharing the unused processor cycles of their PCs in the vast search for signs of "rational" signals from outer space. According to John Patrick, IBM's vice-president for Internet strategies, "the next big thing will be grid computing." |
GroupWise
| a groupware product developed by Novell that provides a wide range of collaboration features.

(GSM) Global Standard for Mobile Computing
| Standard for cellular services found widely in Europe and in some other countries, but not in the U.S. and not a truly global standard for cellular service.
|
Hard Disk
| part of the hard drive that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of surfaces.
|
Hardware
| physical aspect of computers, telecommunications, and other information technology devices.
|
(HFC) Hybrid Fiber Coax
| are second generation cable TV infrastructure. HFC networks combine both optical-fiber and coaxial cable lines. Optical fiber runs from the cable head end to neighborhoods of 500 to 2,000 subscribers. Coaxial cable runs from the optical-fiber feeders to each subscriber. Hybrid networks provide many of fiber's reliability and bandwidth benefits at a lower cost than a pure fiber network. With two-way communications, HFC enables cable operators to offer two-way communications, providing subscribers with Internet access, telephone service over the cable as well as full interactive access to broadband signals, including hundreds of channels of interactive TV, digital services, and more. The theoretical size of the cable link is very large-a total of some 735 MHZ usable bandwidth. HFC divides the total bandwidth into a downstream (to the home) band and an upstream (to the hub) band. The downstream band typically occupies 50-750 MHZ, while the upstream band typically occupies from 5-40 MHZ.

| HSPD-7 | HSPD-7 (Homeland Security Presidential Directive No. 7) is a directive that was issued by U.S. President George W. Bush in December, 2003 to update policies intended to protect the country from terrorist attacks. This directive superseded the earlier PDD-63 (Presidential Decision Directive No. 63), which was issued by President Clinton in May of 1998. The original purpose of PDD-63 (which predated the September 11, 2001 attacks) was to require federal agencies to ensure the continuity and viability of physical and computer-based systems essential for minimal functioning of the U.S. government and economy in case of a terrorist attack. Under HSPD-7, federal departments and agencies are required to develop methods and technologies to protect all critical infrastructures and key resources of the government and economic sector |
(HTTP) Hypertext Transfer Protocol
| set of rules for exchanging files on the World Wide Web.
|
Hyperlink
| synonym for link or hypertext link.
|
| HyperTerminal | HyperTerminal (also known as HyperTerm) is a communications and terminal emulation program that comes with the Windows operating system, beginning with Windows 98. HyperTerminal can be used to set up a dial-up connection to another computer through the internal modem using Telnet or to access a bulletin board service (BBS) in another computer. It can also be used to set up a connection for data transfer between two computers (such as your desktop computer and a portable computer) using the serial ports and for serial port control of external devices or systems such as scientific instruments, robots, or radio communications stations. HyperTerminal can also be used as a troubleshooting tool when setting up and using a modem. You can send commands through HyperTerminal to make sure that your modem is connected properly. |

Identifiers
| an identifier is a function that maps real-world subjects into name or character strings, so that distinct subjects have distinct strings. A real-world subject may be a person, an object (i.e.: a printer or a file), a group, or a department. A real-world subject can have multiple identifiers. When campuses seek to interoperate, issues will arise on the type of identifier that needs to be exchanged, and the forms and policies for that identifier. Moreover, to the degree that identifiers enable users to access other forms of electronic credentials, there may need to be agreements and consistency between campuses about the policies associated with classes of identifiers.

| Incident Response | Incident response is an organized approach to addressing and managing the aftermath of a security breach or attack (also known as an incident). The goal is to handle the situation in a way that limits damage and reduces recovery time and costs. An incident response plan includes a policy that defines, in specific terms, what constitutes an incident and provides a step-by-step process that should be followed when an incident occurs. |
| Intelligent Database | An intelligent database is a full-text database that employs artficial intelligence (AI), interacting with users to ensure that returned items (hits) contain the most relevant information possible. This is in contrast to a traditional database, which is searchable only by keywords and verbatim phrases connected by Boolean operations such as AND, OR, and NOT. Intelligent database technology is in its infancy, and is evolving as AI becomes more advanced. |
(IDS) Intrusion Detection System
| combination of hardware and software products that are used to analyze network traffic passing through a single point on the network. The software analyzes the data searching for specific signatures (known patterns of traffic) of malicious intent. More sophisticated systems are capable of taking immediate action to terminate connection, to send an alert to an attendant or to log activity.

Internet2
| high speed networking infrastructure that includes extremely high bandwidth, management techniques and products that support levels and quality of service. Over 170 U.S. universities, working together with partners in industry and government, are leading the Internet2 project. Internet2 is working to enable applications, such as telemedicine, digital libraries and virtual laboratories that are not possible with the technology underlying today's Internet. As a project of the University Corporation for Advanced Internet Development (UCAID), the Internet2 project is not a single separate network, but rather joins member network application and engineering development efforts together with many advanced, campus, regional, and national networks.
