Because in a token ring network, all computers can send to the next computer at the same time,

Uh no, it's called a token ring because you have a token Which means you only send when you have it. Unless we are talking about 'can I have the token'


whereas CAN shares the same bus so only 1 device can talk. Before the device can talk, it must ask permission from the host, then the host will give permission. All these are done by sending messages.
Why gosh, almost sounds like a token ring Almost
