1. Ring network
1.1. Transmission medium Guided coaxial cable, twisted pair cable, optical fiber.
1.1.1. The signal passes along the ring in one direction, or from device to device, until it reaches its destination. Each device of the ring incorporates a repeater.
1.1.2. In this type of network communication is given by the passage of a token or witness.
2. Network in tree
2.1. Transmission medium Guided coaxial cable, twisted pair cable, optical fiber.
2.1.1. Device are connected to a secondary concentrator which, in turn, is connected to the central concentrator.
2.1.2. However, not all devices are connected directly to the central hub. Most devices are connected to a secondary concentrator which, in turn, is concentrated to the central concentrator.
3. Mesh net
3.1. Guided transmission medium, wireless, coaxial, twisted pair, all non-guided access methods.
3.1.1. Device has a point-to-point link and dedicated with any other device.
3.1.2. The term dedicated means that the link conducts the traffic only between the two devices it connects.
4. Cell network
4.1. Unguided transmission medium
4.1.1. Device needs only one link and one input / output port.
4.1.2. Composed of circular or hexagonal areas, each of which has an individual node in the center.
5. Mixed network
5.1. Transmission medium, guided coaxial cable, twisted pair cable, fiber optic.
5.1.1. Device needs only one link and one input / output port.
5.1.2. Does not allow direct device traffic. The controller acts as an exchanger: if one device wants to send data to another, it sends the data to the controller, which relays it to the final device.
6. Star network
6.1. Transmission medium, Guided coaxial cable, twisted pair cable, optical fiber.
6.1.1. Device needs only one link and one input / output port.
