STAR topology
• Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages.

The star topology has the
form of a star, thats why it Gots its name, in the center it has a switch that sends signal to all the computers conected to it.When a conection is interferenced, it
doesn`t affects the other conection.

BUS topology
• A bus network uses a multi-drop transmission medium, all node on the network share a common bus and thus share communication. This allows only one device to transmit at a time. A distributed access protocol determines which station is to transmit. Data frames contain source and destination addresses, where each station monitors the bus and copies frames addressed to itself.

• A bus topology connects each computer (nodes) to a single segment trunk (a communication line, typically coax cable, that is referred to as the 'bus'. The signal travels from one end of the bus to the other. A terminator is required at each to absorb the signal so as it does not reflect back across the bus

Ring topology
• Also known as a ring network, the ring topology is a type of computer
network configuration where each network computer and device are connected to each other forming a large circle (or similar
shape). Each packet is sent around the ring until it reaches its final destination. Today, the ring topology is seldom used.

• The ring topology is rarely used in now days. When one
conection is Interferenced, all the conection are affected.
