This document provides information about token ring networks. It discusses that a token is a series of bits that circulates a token ring network, allowing only one computer to transmit data at a time. It describes how a Local Area Network (LAN) connects devices within a small geographic area. Token ring was developed by IBM as an alternative to Ethernet and involves computers connected in a ring or star topology passing logical tokens to allow transmission. The document outlines the unidirectional flow of tokens and how different types of token ring networks like physical, dual, bus, and star topologies work. It compares token ring networks to Ethernet networks, noting token ring uses deterministic access while Ethernet uses non-deterministic CSMA/CD access.
3. TOKEN
Token is series of bits that circulate on
token ring network.
Token takes data from sender and move
towards destination point.
There is only one token for each token ring
network.
One computer only data can send at a time.

4. LAN
Local Area Network
A LAN is a network infrastructure that
spans a small geographical area.
Interconnect end devices in a limited area.
Administered by a single organization or
individual.
Provide high-speed bandwidth to internal
devices

5. Token Ring
Token ring was developed in the early
1980’s by IBM for LAN.
It was in direct competition with Ethernet.
A token ring network is used in local area
network.
A token ring network all computers are
connected in a ring or star topology and
pass one or more logical tokens from host
to host.
Only a host that holds a token can send
data and tokens are released when receipt
of the data is confirmed.

6. How token ring works
6
Token moves in one direction that is called
uni direction.
Token revolve every time in ring topology If
A computer wants to send data to C then A
hold token and fill up data in token then it
send to C.
8. PhysicaltokenRing
This one visible ring where token
work in token ring.
Devices are connected with each
other in ring shape
If wire damage then system not
work.
9. DualtokenRing
Dual ring Bothe side devices are
connected outgoing and incoming
Primary and secondary ring
If ring primary damage then
secondary ring will work on ring
10. BusTokenRing
In Bus ring we can not see physical
shape as ring topology but it will
work as ring.
11. StarTokenRing
In Star token ring the devices are
connected through hub.
star token ring message pass through
hub.
If one device damage then others
devices working.

Token Ring Ethernet
The local area network which has the
properties to transmit the node only when
it has certain pieces in succession that
come from the other successive nodes turn
by turn.
The system used for connecting various computers
to form a local area network and has different
protocols to ensure the passage of information
takes place smoothly.
Deterministic Non-deterministic
Delay start to occur whenever the load
becomes low.
The flow stays the same even if the load becomes
less or more.
A token-passing system which has only one
workstation to call upon at one instant.
Collision Sense Multiple Access/Collision Detection
(CSMA/CD) topology.
