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 Detection

CSMA mean Carrier Sense Multiple Access

6. 
Ethernet was originally developed in 1976

It was developed by Xerox PARC

The idea was first documented in 1973

It was patented in 1975

7. Ethernet Generations

Ethernet has gone through 4 generations
1.
STANDARD EHTERNET
2.
FAST ETHERNET
3.
GIGABIT ETHERNET
4.
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 flexible
10BASET: TWISTED PAIR(10 Mbps/100m)


It uses a bus topology with an external transmitter/receivers
It uses a star topology and uses a twisted pair cable
10BASEF: FIBER EHERNET(10 Mbps/2000m)

It also uses a star topology but it uses a fiber optic cable

11. 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 is
transmission performance.

12. Types of Fast Ethernet

There are two types of fast Ethernet

(a)100Base-TX

100Base-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

13. GigaBit Ethernet

Upgrade the data rate to 1Gbps

Make it compatible with standard or Fast Ethernet

It has same technology that was created in 1970s.

Maximum length of 1000Base-LX is 5000m

Maximum length of 1000Base-T is 100m

14. 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
implementation
1000Base-LX
1000Base-LX
1000Base-CX
1000Base-T

15. 10 GigaBit Ethernet

Upgrade the data rate to 10 Gbps

Use same frame format

Keep the same minimum and maximum frame length

Make ethernet compatible with ATM

16. 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

17. 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.

18. 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.

19. 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 LAN’S 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.

20. 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.

21. 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.
