bridge - a product that connects one local area network (LAN) to another local area network that uses the same protocol. http://searchsecurity.techtarget.com/sDefinition/0,,sid14_gci211705,00.html?track=NL-35&ad=477840 BNC connector - used to connect a computer to a coaxial cable in a 10BASE-2 Ethernet network. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci211681,00.html?track=NL-35&ad=477840 Carrier Sense Multiple Access/Collision Detect (CSMA/CD) - the protocol for carrier transmission access in Ethernet networks. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci213869,00.html?track=NL-35&ad=477840 Coaxial cable - the kind of copper cable used by cable TV companies between the community antenna and user homes and businesses. It is also widely installed for use in business and corporation Ethernet and other types of local area network. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci211806,00.html?track=NL-35&ad=477840 collision - the result of two devices on the same Ethernet network attempting to transmit data at exactly the same time. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci211814,00.html?track=NL-35&ad=477840 Ethernet - the most widely-installed local area network (LAN) technology. Specified in a standard, IEEE 802.3, Ethernet was originally developed by Xerox and then developed further by Xerox, DEC, and Intel. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212080,00.html?track=NL-35&ad=477840 Ethernet/IP (Ethernet Industrial Protocol) - a network communication standard capable of handling large amounts of data at speeds of 10 Mbps or 100 Mbps, and at up to 1500 bytes per packet. The specification uses an open protocol at the Application layer and is especially popular for control applications. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci940057,00.html?track=NL-35&ad=477840 Fast Ethernet - a local area network (LAN) transmission standard that provides a data rate of 100 megabits per second (referred to as "100BASE-T"). http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212094,00.html?track=NL-35&ad=477840 frame - the unit of data that is transmitted between network points on an Ethernet network. It has explicit minimum and maximum lengths and a set of required pieces of information that must appear within it. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212152,00.html?track=NL-35&ad=477840 Gigabit Ethernet - a transmission technology based on the Ethernet frame format and protocol used in local area networks (LANs), provides a data rate of 1 billion bits per second (one gigabit). Gigabit Ethernet is defined in the IEEE 802.3 standard and is currently being used as the backbone in many enterprise networks. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212193,00.html?track=NL-35&ad=477840 jabber - a device that is handling electrical signals improperly. In an Ethernet network, a jabber can look like a device that is always sending, effectively bringing the network to a halt. A jabber is usually the result of a bad network interface card (NIC). http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212412,00.html?track=NL-35&ad=477840 network interface card (NIC) - a computer circuit board or card that is installed in a computer so that it can be connected to a network. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci212660,00.html?track=NL-35&ad=477840 Power over Ethernet (PoE) - a technology for wired Ethernet LANs (local area networks) that allows the electrical current necessary for the operation of each device to be carried by the data cables rather than by power cords. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci846792,00.html?track=NL-35&ad=477840 10BASE-T - ordinary telephone twisted pair wire; one of several physical media specified in the IEEE 802.3 standard for Ethernet local area networks (LANs). http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci211491,00.html?track=NL-35&ad=477840 10-Gigabit Ethernet - a developing telecommunication technology, being standardized in IEEE 802.3a, that offers data speeds up to 10 billion bits per second. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci535824,00.html?track=NL-35&ad=477840 Thicknet and Thinnet - commonly used terms for the larger and smaller size of coaxial cable used in Ethernet local area networks. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci213134,00.html?track=NL-35&ad=477840 vampire tap - used to connect each device to Thicknet coaxial cable in the bus topology of an Ethernet 10BASE-T local area network. http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci213528,00.html?track=NL-35&ad=477840 ____________________________________________________________________ ::::::::::::::::::: WHATIS.COM CONTACTS ::::::::::::::::::: MARGARET ROUSE, Site Editor ([EMAIL PROTECTED]) IVY WIGMORE, Consulting Editor ([EMAIL PROTECTED]) LOWELL THING, Consulting Editor and Founder ([EMAIL PROTECTED]) GABRIELLE DERUSSY, Advertising ([EMAIL PROTECTED]) ::::::::::::::::::::: ABOUT THIS NEWSLETTER :::::::::::::::::::::: This e-newsletter is published by WhatIs.com, a targeted Web site from TechTarget, the most targeted IT media and events company.
