Ethernet Standard EthernetFast EthernetGigabit EthernetTen Gigabit EthernetToken RingFiber Distributed Data Interface(FDDI)Asynchronous Transfer Mode(ATM) 4. ETHERNETHISTORYGENERATIONSTYPES (Categories of standard Ethernet) 5. What is Ethernet ?Ethernet is the most widely-installed local area network ( LAN) technology.An Ethernet LAN typically uses coaxial cable or twisted pair wires.Speed 1 Mbps to 10 Gbps.Ethernet use (CSMA/CD ) for transmission of data.CD mean Collision DetectionCSMA mean Carrier Sense Multiple Access 6. Ethernet was originally developed in 1976It was developed by Xerox PARCThe idea was first documented in 1973It was patented in 1975 7. Ethernet Generations Ethernet has gone through 4 generations 1.STANDARD EHTERNET2.FAST ETHERNET3.GIGABIT ETHERNET4.10 GIGABIT ETHERNET 8. 10BASE5: THICK ETHERNET(10 Mbps/500m) 10BASE2: THIN ETHERNET(10 Mbps/185m) The only difference is that cable is thinner and more flexible10BASET: TWISTED PAIR(10 Mbps/100m) It uses a bus topology with an external transmitter/receiversIt uses a star topology and uses a twisted pair cable10BASEF: FIBER EHERNET(10 Mbps/2000m) It also uses a star topology but it uses a fiber optic cable 9. Fast Ethernet It also called 100BASE-T using the same media and topology as Ethernet.Upgrade the data rate to 100Mbps.Maximum length 100m.This type of network commonly uses Cat 5.A new standard is called Cat 6.General difference b/w Cat 5 & Cat 6 istransmission performance. 10. Types of Fast Ethernet There are two types of fast Ethernet(a)100Base-TX100Base-TX(b)100Base-FX(1) it uses two twisted pair cable(Cat 5) (2) This creates the data rate of 125Mbps 100Base-FX(1) It uses two pair of fiber-optic cables (2) This creates the 100 to 125 Mbps (3) A new standard is called 100Base-T4 11. GigaBit Ethernet Upgrade the data rate to 1GbpsMake it compatible with standard or Fast EthernetIt has same technology that was created in 1970s.Maximum length of 1000Base-LX is 5000mMaximum length of 1000Base-T is 100m 12. Types of Gigabit Ethernet (1) 1000Base-SX or 1000Base-L(550m,5000m) Both uses the two wire implementation use fiber-optic cable(2) 1000Base-T(100m) 4 wire implementation Gigabit Ethernet implementation1000Base-LX1000Base-LX1000Base-CX1000Base-T 13. 10 GigaBit Ethernet Upgrade the data rate to 10 GbpsUse same frame formatKeep the same minimum and maximum frame lengthMake ethernet compatible with ATM 14. Types of 10-Gigabit Ethernet (1)10GBase-S (a) maximum length 300m(b)short wave media technology is used (2)10GBase-L (a)maximum length 10Km (b) long wave media technology is used (3) 10GBase-E (a)maximum length 40Km (b) extended media technology is used 15. Token Ring What is token ring ? (a) A local area network in which a node can only transmit when possession of a sequence of bits (the token), which is passed to each node in turn.Token ring use a ring topology to send from one machine to another.Token ring operated at 4 or 16 Mbps.Token ring networks are vary rare because of cost. 16. Working of Token Ring Token Ring transmits an electric token(small set of data) to each node of the network.Computer copy the data in Token and set the address where the dada is send.Token goes to every computer.Computer save the data and send acknowledgment to sending computer. 17. Fiber Distributed Data Interface(FDDI) What is FDDI ? FDDI (Fiber Distributed Data Interface) is a set of ANSI and ISO standards for data transmission fiber optic lines in a local area network (LAN).It use to connect two or more LANS often over long distance.It also use to make physical topology with dual rings.A router or a switch is used to for linking an FDDI. 18. FDDI has the following Characteristics Fiber optic is the cable used.Token passing is its media accessing method.100 Mbps speed.100 Km is the maximum length of the network.500 is the maximum number of nodes on the network. 19. Asynchronous Transfer Mode(ATM) Atm is a high-speed networking standard designed to support both voice and data communications.ATM has capability to transferring of data at a speed of 155 Mbps or more.Data is transfer in the form of packets of fixed size.Various types of media are supported eg(CD quality audio , video & Imaging)ATM use Star topology , which has advantage working with both twisted or fiber optic cables.Two or more LAN are connected by ATM.
