ring topology uses token ring i.e one way communication which passes the token with header and Destination address into the network.If one client in the network just disconectd from the network then the the entire network collapse. For this problem FDDI is used for fault tolorence Where as ethernet works much efficiently in packet delivering
no. The differences between ethernet and token ring are greater then the frame type. Ethernet uses CDMA and token ring uses.....well a token. Token ring adapters have an on-board processor for source route bridging which uses a RIF field and ethernet has nothing of the sort. There are many more examples, but the simple answer is it will not work. fm

Essentially, you don't ... the data link layer is used by the underlying protocol of the LAN. If it is an Ethernet network then the frame is constructed as an Ethernet frame in layer 2. If you are using Token Ring, then you get a Token Ring frame, etc.
They are more expensive and are slower than Ethernet.
No. Ethernet and token ring have now become standards. However, the access method and the standard are not always the same. Ethernet is based on IEEE 802.3 standards, but is not exactly the same as IEEE 802.3. Some vendors' IEEE 802.3 equipment will not work with ethernet. Token ring and 802.5 are the same, despite token ring's origins as an IBM proprietary standard. Non-IBM vendors can provide 802.5 equipment that will work with IBM token rings, provided the equipment follows 802.5 standards
less chance of collisions. however TCP/IP resends data if its not acknowledged so in todays high performance switching equipment ethernet rules the roost for scalability and ease of implementation
Saguaro Federal should use Token ring protocol, as it appears there are multiple locations. Ethernet protocol could be appropriate if everything was located in the same building.
A token bus uses a shared bus for communication. Hosts on the bus are ordered in a logical ring, with access to the bus coordinated by passing a token (a special packet) around the ring, indicating permission to transmit. The intent is to get the robustness of a simple bus protocol with the deterministic response time of a token ring. Unfortunately, because the bus is shared, each host on the bus must wait for the token to be completely transmitted before it can pass it on. This is in contrast to a token ring, where the token passes through each host with only a few bits delay. This gives the token bus considerably worse latency than a token ring. The reliability of a token protocol over a (CSMA protocl such as Ethernet ) is undermined by the complex protocols needed to recover the token at exactly one host should it become corrupted.
Since there is no protocol known as Ethernet Token Ring I assume you are asking about the difference between Ethernet, Token Ring, and Token Bus usage. These are all different protocols, so connecting all three types of networks is not practical. Token Bus networks were an early attempt to get mainframes to connect to terminals through a bus topology structure, utilizing a token for arbitration. Those networks typically ran at 4 Mbps. They were also subject to the same problem as a linear bus structure with Ethernet, which is a break in the cable would bring down the entire network. A later version of Token ring uses a ring topology structure, where a failure in the network will not bring down the entire network. It still uses a token for station arbitration, but can ran at 16 Mbps. Newer versions of HSTR can run at 100 Mbps and there is a standard for a gigabit version. Chances are you will need to bridge between Ethernet and Token Ring (not token bus). For that, you will need a bridge, router, or gateway that can convert between the protocols. In some cases the media is different as well, going from coaxial cable to unshielded twisted pair (UTP). So the difficulties are in correctly converting the protocols between the two, connecting different media types together, and troubleshooting problems between the two networks.
You will need a router. Token Ring and Ethernet refer to two different layer two protocols. You will need a layer three device to encapsulate the data for communication between the two networks. A bridge refers to a layer two device.
3. Unlike Ethernet, Token Ring uses a ring topology whereby the data is sent from one machine to the next and so on around the ring until it ends up back where it started. It also uses a token passing protocol which means that a machine can only use the network when it has control of the Token, this ensures that there are no collisions because only one machine can use the network at any given time.
Advantage: No packet collisions Disadvantage: Single point of failure
A token bus is a type of network which uses the token ring protocol. The protocol is implemented over a virtual ring using coaxial cable. A token is passed around the ring, so that only one computer has the right to transmit data. If the chosen computer doesn't have any data to transmit, the token is passed to the next computer.
oken-Ring was initially successful for IBM - as most IBM-endorsed technologies are. But beyond IBM, it never garnered much support among top-tier vendors, which gravitated toward Ethernet, the preferred LAN technology of research institutions and manufacturing companies.Token-Ring began its downward spiral soon after the emergence of 10Base-T Ethernet, an inexpensive, 10Mbps transmission technology than ran across telephone grade unshielded twisted-pair copper media. Matters were not helped when Soderblom began demanding royalties from the few Token-Ring vendors and chip makers, driving prices higher.Stations on a token ring LAN are logically organized in a ring topology with data being transmitted sequentially from one ring station to the next with a control token circulating around the ring controlling access. This token passing mechanism is shared by ARCNET, token bus, and FDDI, and has theoretical advantages over the stochastic CSMA/CD of Ethernet. Physically, a token ring network is wired as a star, with 'hubs' and arms out to each station and the loop going out-and-back through each. Cabling is generally IBM "Type-1" shielded twisted pair, with unique hermaphroditic connectors, commonly referred to as IBM data connectors. The connectors have the disadvantage of being quite bulky, requiring at least 3 x 3 cm panel space, and being relatively fragile.Initially (in 1985) token ring ran at 4 M bit/s, but in 1989 IBM introduced the first 16 M bit/s token ring products and the 802.5 standard was extended to support this. In 1981, Apollo Computer introduced their proprietary 12 M bit/s Apollo token ring (ATR) and Proteonintroduced their 10 M bit/s ProNet-10 token ring network in 1984. However, IBM token ring was not compatible with ATR or ProNet-10. Each station passes or repeats the special token frame around the ring to its nearest downstream neighbor. This token-passing process is used to arbitrate access to the shared ring media. Stations that have data frames to transmit must first acquire the token before they can transmit them. Token ring LANs normally use differential Manchester encoding of bits on the LAN media.IBM popularized the use of token ring LANs in the mid 1980s when it released its IBM token ring architecture based on active MAUs (Media Access Unit, not to be confused with Medium Attachment Unit) and the IBM Structured Cabling System. The Institute of Electrical and Electronics Engineers (IEEE) later standardized a token ring LAN system as IEEE 802.5.Token ring LAN speeds of 4 Mbit/s and 16 Mbit/s were standardized by the IEEE 802.5 working group. An increase to 100 Mbit/s was standardized and marketed during the wane of token ring's existence while a 1000 Mbit/s speed was actually approved in 2001, but no products were ever brought to market.
Token ring hub
assuming the DE-528CT CARDS ARE COMPATIBLE WITH THE OFFICE NETWORK,DOES THE LAN USE ETHERNET OR TOKEN RING?
Typically you would need a gateway for this purpose, because the protocols are very different. In my HP server, for example, I have two NIC cards; one of the NICs connects to a Token Ring network and the other connects to an Ethernet network. The software in the HP server (gateway) manages the translation between the two different types of networks.
In a token bus network architecture, the nodes at either end of the bus do not actually meet. In a token ring, the network logically functions as a ring, but is wired as a star.
It is a 'token' of your affection for that person.
That is not possible. In Token Ring, only the station with the token can transmit.
