Many home networks use the star topology. A star network features a central connection point called a "hub" that may be a hub, switch or router. Devices usually connect to the hub with Unshielded Twisted Pair Strengths Easy to Install, Flexible IF single device or cable failure will not bring down the network Weakness If the centralize device fails the entire system is affected Bus
Bus is the simplest network topology. All computers are connected to a single cable that makes a connecting Ethernet. Computers decide when network is not busy and communicates data as needed. Bus computers listen to transmissions from other computers and do not forward or echo transmissions to other computers Weakness Limited cable length and number of stations, If there is a problem with the cable, the entire network goes down, Low security Strengths Requires less cable length than a star topology, Flexible Ring
In a ring network, every device has exactly two neighbors for communication purpose. All messages travel through a ring in the same direction, either "clockwise" or "counterclockwise". A failure in any cable or device breaks the loop and can take down the entire network. To implement a ring network, one usually uses FDDI, SONET, or Token Ring technology. Ring topologies are found in some office buildings or school campuses. Strengths All devices have equal access. Adding additional nodes has very little impact on bandwidth . Weakness Data packets must pass through every computer between the sender and recipient Therefore this makes it slower. It is difficult to troubleshoot the ring.
