This paper is about networking structure and what this structure is all about, what it does and what happens when it doesn’t work.
In a bus network, there is a use of a backbone or main line that connects all devices. The single cable functions as a shared communication media that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message.
Ethernet bus topologies are relatively easy to install and don’t require much cabling compared to the alternatives. 10Base-2 (Thin Net) and 10Base-5 (Thick Net) both were popular Ethernet cabling options many years ago for bus topologies. However, bus networks work best with a limited number of devices. If more than a few dozen computer are added to a network bus, performance problems will likely result. In addition, if the main cable fails, the entire network crashes.
1. It’s easy to setup, handle and implement.
2. It’s best suited for small networks.
3. It very low in cost.
1. The cable length is limited. This limits the number of networks nodes that can be connected.
2. This network topology can perform well only for a limited number of nodes. When the number of devices connected to the bus increases, the efficiency decreases.
3. It’s suitable for networks with low traffic. High traffic increases load on the bus and the efficiency drops.
4. It’s heavily dependent on the center main cable. A fault in the bus leads to network failure.
5. Each device on the network “sees” all data being transmitted, thus posing a security risk.
In a ring network, every device has exactly 2 neighbors for communication purposes. All messages travel through a ring in the same direction (either “clockwise” or “counter-clockwise”). A failure in any cable or a device...
