Bus Topology is one of the oldest connection technologies. In Bus Topology, one computer should be at least 1m away. It can be extended with extension. The bus uses 10 base 2. 10 base 2 means 10 means speed (10 Mbps) and 2 means distance 185m. Buses use terminators with both ends off.
Star Topology
Star Topology is a separate application from Central Point. For example, switch through the Hub / Switch. Using the Star is easy to troubleshoot and can be used over a distance of over 300 m. Star is commonly used in current network systems. The advantages of star topology are that if a single cable fails, the system will not be affected and troubleshooting will be easier. Disadvantages are the large cost of installing large cables. A single device error can cause the entire system to crash. Star can also be connected to a wireless device.
