Give two examples of a ‘collision-free’ protocol ?
Answer / Nitin Jeet Kumar
A collision-free protocol is a communication protocol that prevents simultaneous transmissions, or collisions, from occurring in a network. Here are two examples:
1. Token Ring: A local area network (LAN) protocol where data transmission is controlled by a special packet called a token. Each device in the network can only transmit when it possesses the token and must relinquish control to the next device after transmitting. This prevents simultaneous transmissions and reduces collisions.
2. Fiber Distributed Data Interface (FDDI): A high-speed LAN protocol that uses a dual-ring topology for data transmission. One ring is used for normal data traffic, while the other ring acts as a backup in case of failure on the primary ring. This provides fault tolerance and reduces the likelihood of collisions.
