Ring topology refers to how computers can be connected directly without the need for devices. There are similarities between Bus Topology and Theory. When connected in the ring topology, data can collide with each other during transfer.
Ring is usually used for Banking & Train Station etc. It is widely used in Rings transfer data collisions if they transfer one after the other, causing data delays. If we were connected to a ring, I would send data from machine 1 at the same time, machine 2 would send data, and then there would be a collision between the data and the data would be junk. Then they take back the timing. Timing is controlled by the CPU. MAC Priority (Multi Access Access Controller) Prefers large machine data. In other words, the sender first enters. When attacked, a large MAC machine enters first. This is called Ring
