Token Ring and IEEE 802.5 networks are basically compatible, although the specifications differ in minor ways. IBM's Token Ring network specifies a star, with all end stations attached to a device called a multistation access unit (MSAU).

In contrast, IEEE 802.5 I Ethernet ) does not specify a topology, although virtually all IEEE 802.5 implementations are based on a star. Other differences exist, including media type (IEEE 802.5 does not specify a media type, although IBM Token Ring networks use twisted-pair wire) and routing information field size. Figure 9-1 summarizes IBM Token Ring network and IEEE 802.5 specifications.

criteria are used to determine the Pros and Cons of Ethernet and Token Ring:-
Ability for trouble shooting
Token Ring is better than Ethernet. Test procedures are invoked every time a systems first accesses the ring. If one of the procedures fails, messages are generated to indicate the possible causes of failure, including suspicious addresses. In ethernet, however, problems are identified through a series of isolated procedures.
Easier Installation
Ethernet is easier to install because of the flexibility to mix and match different kinds of topologies ( hub or star, bus, and tree ) makes it extremely easy to implement an Ethernet network of any size. On the other hand, Token Ring requires a hub where connections are made to the main Multi-station Access Unit with any other system or hub.
Multi-vendor Environment
Ethernet is the choice because most non-IBM systems support it as the primary LAN. Examples are Digital Euqipment, Hewlett Packard, and Sun Microsystems.

Ability to support more users
The upper limit for an isolated LAN is around 200 systems. Small LANS of both Ethernet and Token Ring can be established and then interconnected.
When there are frequent accesses to the network
Ethernet is less suitable when many users have to access information through the network. An example would be a travel reservation company in which the agents need to retrieve data across a LAN. They may check whether flights and hotel rooms are available at first, then proceed to make bookings. These "frequent calls" to the network will lead to fluctuation of levels of performance. To remedy this problem, the Ethernet can be divided into segments.
