Network+ Guide to Networks, 5th Edition

The layout of How a network communicates with different devices is called a "TOPOLOGY" and the most common topology is the "Star Topology" In a Star Topology all Computers are connected to the central wiring point such as a Hub or a Switch and all data on star network passes through the central point before continuing to its destination when is the major benefits of this topology is that if there is one computer failed or if there was a break in a cable the other computers were not be effected because each computer has there own cable connecion however a disadvantage of a star topology is that if central hub or switch fails, the other computers on that central point would be effected and this is called a "Single Point of Failure" if this happens the entire network goes down. this is called bus topology that is topology is very old technology and it is not use today that much. this
