Ethernet 音标拼音: ['ɛθɚn,ɛt] 以太网 ;
(一种以基频通讯技术为基础的高传输网络硬件标准。是一个很受欢迎的局域网络) 乙太网 ; (一种以基频通讯技术为基础的高传输网络硬体标准。是一个很受欢迎的局域网络) ethernet 以太网路 ethernet n 1: a type of network technology for local area networks; coaxial cable carries radio frequency signals between computers at a rate of 10 megabits per second Metcalfe & Boggs of {Xerox PARC} in 1976. Specified by {DEC}, {Intel} and {XEROX} (DIX) as {IEEE 802.3} and now recognised as the industry standard. Data is broken into {packets} and each one is transmitted using the {CSMA/CD} {algorithm} until it arrives at the destination without colliding with any other packet. The first {contention slot} after a transmission is reserved for an {acknowledge} packet. A {node} is either transmitting or receiving at any instant. The {bandwidth} is about 10 Mbit/s. Disk-Ethernet-Disk transfer rate with {TCP/IP} is typically 30 kilobyte per second. Version 2 specifies that {collision} detect of the transceiver must be activated during the {inter-packet gap} and that when transmission finishes, the differential transmit lines are driven to 0V (half step). It also specifies some {network management} functions such as reporting {collisions}, retries and {deferrals}. Ethernet cables are classified as "XbaseY", e.g. 10base5, where X is the data rate in {Mbps}, "base" means "{baseband}" (as opposed to {radio frequency}) and Y is the category of cabling. The original cable was {10base5} ("full spec"), others are {10base2} ("thinnet") and {10baseT} ("twisted pair") which is now (1998) very common. {100baseT} ("{Fast Ethernet}") is also increasingly common. {Usenet} newsgroup: {news:comp.dcom.lans.ethernet}. {(http://wwwhost.ots.utexas.edu/ethernet/ethernet-home.html)}.
