c. Four advantages of ring topology:
1. Easy to install and configure: Ring topology simply requires connecting each device in a ring or loop, making it relatively easy to set up and manage.
2. Efficient data transfer: In ring topology, data travels in a circular manner from one device to another, allowing for efficient and consistent data transfer.
3. No data collisions: Since each device in the network has its own dedicated communication path, there are no data collisions, resulting in a more reliable and stable network.
4. Easy scalability: Adding or removing devices in a ring topology is quite simple, making it easy to scale up or down the network as per requirements.
