Glossary hub A networking device that enables attached devices to receive data transmitted over the network. Most networks need a hub to help modify transmission signals and to extend the network past two workstations. HVAC heating, ventilation, air conditioning A common acronym for the environmental systems in your home. hypertext The text on the page that supplies the links. When you click on these links — rep- resented as underlined text, and often as graphics, on a Web page — you “jump” to another Web page. Using links, you can view information or images related to the original topic. Hypertext Markup Language See HTML. Hypertext Transfer Protocol See HTTP. ICMP Internet Control Message Protocol One of the TCPIP protocols. It helps IP communi- cate error information about the IP transmissions. IDE Integrated Device Electronics A popular hard disk interface standard that provides only medium-to-fast data transfer rates. IEEE Institute of Electrical and Electronic Engineers Networking cabling and other equipment have standards that are set by the IEEE to ensure interoperability of products and services from vendor to vendor. IGMP Internet Group Management Protocol One of the TCPIP protocols. It enables IP datagrams to be broadcast to computers that belong to groups. incremental backup This type of backup backs up only the files that have changed since the last incremental or full backup. Industry Standard Architecture See ISA. infrared A method of wireless networking connection using high-frequency light waves instead of cabling to transmit data. With infrared, you must have a clear line of sight between the two computers, because the light waves cannot penetrate obstacles. inputoutput See IO port. Institute of Electrical and Electronic Engineers See IEEE. Integrated Device Electronics See IDE. Integrated Services Digital Network See ISDN. intelligent home also SmartHome or smart home Intelligent homes vary from those hav- ing simple motion detectors outside to those that are fully connected and fully wired with automatic heating and cooling, security cameras, whole-house video and audio, and more.

Internet An internetwork of smaller networks that spans the entire world. Each smaller net- work contains servers that display information of various types on the Web WWW, or World Wide Web. The Internet is a public network, available to all who have a computer with the appropriate software and a connection to the Internet.
