Star Network vs Bus Network
Summary: Difference Between Star Network and Bus Network is that on a star network, all of the computers and devices (nodes) on the network connect to a central device, thus forming a star. While bus network consists of a single central cable, to which all computers and other devices connect. The bus is the physical cable that connects the computers and other devices.
Star Network
On a star network, all of the computers and devices (nodes) on the network connect to a central device, thus forming a star. Two types of devices that provide a common central connection point for nodes on the network are a hub and a switch. All data that transfers from one node to another passes through the hub or switch. Star networks are fairly easy to install and maintain. Nodes can be added to and removed from the network with little or no disruption to the network.
On a star network, if one node fails, only that node is affected. The other nodes continue to operate normally. If the hub or switch fails, however, the entire network is inoperable until the device is repaired.
Bus Network
A bus network consists of a single central cable, to which all computers and other devices connect. The bus is the physical cable that connects the computers and other devices. The bus in a bus network transmits data, instructions, and information in both directions. When a sending device transmits data, the address of the receiving device is included with the transmission so that the data is routed to the appropriate receiving device.
Bus networks are popular on LANs because they are inexpensive and easy to install. One advantage of the bus network is that comput ers and other devices can be attached and detached at any point on the bus without disturbing the rest of the network. Another advan tage is that failure of one device usually does not affect the rest of the bus network. The greatest risk to a bus network is that the bus itself might become inoperable. If that happens, the network remains inoperative until the bus is back in working order.
