Wireless PCI Adapter Appendix: Glossary Ad.Hoc -- Ad.Hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for an access point. Adapter - Printed circuit board that plugs into a PC to add to capabilities or connectivity to a PC. In a networked environment, a network interface card (NIC) is the typical adapter that allows the PC or server to connect to the intranet and/or Internet. Backbone - The part of a network that connects most of the systems and networks together and handles the most data. Bandwidth - The transmission capacity of a given facility, in terms of how much data the facility can transmit in a fixed amount of time; expressed in bits per second (bps). Bit - A binary digit. The value 0 or 1 used in the binary numbering system. Also, the smallest form of data. Boot - To cause the computer to start executing instructions. Personal computers contain built-in instructions in ROM chip that are automatically executed on startup. These instructions search for the operating system, load it, and pass control to it. Bridge - A device that interconnects different networks together. 51 Wireless PCI Adapter Broadband - A data-transmission scheme in which multiple signals share the bandwidth of a single medium. This allows the transmission of voice, data, and video signals over that medium. Cable television uses broadband techniques to deliver dozens of channels over one cable. Browser - A browser is an application program that provides a way to look at and interact with all the information on the World Wide Web or PC. The word "browser" seems to have originated prior to the Web as a generic term for user interfaces that let you browse text files online. Cable Modem - A device that connects a computer to the cable television network, which in turn connects to the Internet. Once connected, cable modem users have a continuous connection to the Internet. Cable modems feature asymmetric transfer rates: around 36 Mbps downstream (from the Internet to the computer), and from 200 Kbps to 2 Mbps upstream (from the computer to the Internet). Data Packet - One frame in a packet-switched message. Most data communication is based on dividing the transmitted message into packets. For example, an Ethernet packet can be from 64 to 1518 bytes in length. Default Gateway - The routing device used to forward all traffic that is not addressed to a station within the local subnet. 52
