What is Ethernet? Walker 29-July-2007 04:12:26 PMComments Def> The Ethernet is the international standard networking technology for wired implementations. Basic 10BaseT networks offer a bandwidth of about 10 ... Posted by HamidAliKhan Hello! Ethernet, as defined by the Institute of Electrical and Electronic Engineer's (IEEE) 802.3 standard, is an access method that determines how data, in the form of electrical signals, is transmitted across a physical cabling medium that connects computing devices. Ethernet conforms to the carrier sense multiple access with collision detection (CSMA/CD) network access protocol, which essentially allows any station on a network to transmit data at any time. If the network is busy - that is, if another station is already broadcasting - the transmitting station backs off and waits a random length of time (measured in milliseconds) before trying again. Once the network is clear, the station is free to send. The IEEE 802.3 standard features several sub-specifications which define the specific cabling used by that particular Ethernet application. For instance, 10BASE-5 specifies the use of thick coaxial cabling; 10BASE-2 specifies thin coaxial cabling (like cable TV wire); and 10BASE-F, 10BASE-FB, 10BASE-FL and FOIRL all cover fiber optic cabling. Finally, the most popular method - IEEE 802.3I 10BASE-T - specifies the use of unshielded twisted pair telephone cabling with RJ-45 phone jacks for easy connections. Thanks. Posted by stephen |
