Ethernet is used for connections in a local area networking and also uses different protocols for the confirmation of information either they are completely sent or received or not. It is simpler and cheaper then Token rings and ATM.

Ethernet have several types .

Fast Ethernet 

Gigabit Ethernet

 10-Gb Ethernet.

Token rings are the LAN which has the properties to transmit the node only when it has certain successful parts of packets that comes from other nodes one by one. 

Ethernet :gets defined as 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.

ETHERNET: is defined as 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.

An important distinction between the two topologies is that “TOKEN RING” is a token-passing system in which only one workstation can talk at a time. It has to be in posession of the token in the packet; no one else is supposed to be able to talk until their turn comes.  ETHERNET is a Collission Sense Multiple Access/Collission Detection (CSMA/CD) topology.  This means that if multiple workstations start talking at the same time, they will all shut down, wait a randomized period of time and then start up.  What is theoretically supposed to happen is that one workstation will start talking before the others do, and the remaining worsktations will see that someone is talking and remain silent until the current talking workstation has finished. If the vendor of the system you are looking at supports full-duplex Ethernet, you can be looking at a theoretical speed of 200M bit/sec.

TOKING RING: a local area network in which a node can only transmit when in possession of a sequence of bits (the token), which is passed to each node in turn. Also Token Ring is a  local area network (LAN) technology is a communications protocol for local area networks. It uses a special three-byte frame called a "token" that travels around a logical "ring" of workstations or servers.

 

ETHERNET supports a direct cable connection between two network interfaces cards by the use of a crossover cable or through auto-sensing if supported. WHILE TOKEN RING does not inherently support this feature and requires additional software and hardware to operate on a direct cable connection setup.

TOKEN RING eliminates collision by the use of a single-use token and early token release to alleviate the down time. ETHERNET alleviates collision by carrier sense multiple accessand by the use of an intelligent switch, primitive Ethernet devices like hubs can precipitate collisions due to repeating traffic blindly.

 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.

Working: Deterministic

Delays: Delay start to occur whenever the load becomes low.

Type: A token-passing system which has only one workstation to call upon at one instant and

More secure and stable

 

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.

Working: Non-deterministic

Delays: The flow stays the same even if load become less or more.

Type: Collision Sense Multiple Access/Collision Detection (CSMA/CD) topology and the Ethernet Less secure and stable
 
 

Ethernet uses the CSMA/CD specification which stands for "Carrier Sense, Multiple Access / Collision Detect". When a station wants to transmit on the network it first 'listens' to the cable until it detects a quite period where there is no traffic on the network. At this point it will try and transmit its data. If another workstation has also detected the quite period and transmits at the same time you get a collision, and both stations have to wait a random ammount of time before retrying. Waiting for a random time allows one of the workstatins to retransmit first. 

Token Ring devices are often quite a bit more expensive than the ethernet equivalent due to the cost of the extra logic the boards need to have as well as having to have MAU's or CAU's etc.
 
 
 
 Ethernet is available at speeds of 10, 100 and 1000mb/s. There are many tools, utilities and various suppliers of devices for ethernet, whereas the choices for Token Ring are much more limited.
 
 Token ring was more resilient than a coaxial/BNC cabled ethernet network, but UTP with hubs and switches etc these days mean that the cabling can be much more fault tolerent. So assuming that when you talk of ethernet, you ARE talking about UTP structured cabling and not the older coaxial cabling which is prone to noise and failure (a break on one cable segment brings all stations down on that segment) ethernet should give more resilience and easier upgrade/expansion as well as higher speed options.
