Network Reference Models

It is a schematic description of a network arrangement, connecting various nodes (sender and receiver) through lines of connection

• Star Topology

• Network Topologies

• Ring Topology

• Bus Topology

in this type of topology, the computers are connected to a single hub through a cable. This hub is the central node while all other nodes are connected to it.

• Star Topology

• Network Topologies

• Ring Topology

• Bus Topology

a network type in which every computer and network device is connected to a single cable.

• Star Topology

• Network Topologies

• Ring Topology

• Bus Topology

– forms a ring as each computer is connected to another computer, with the last one (1) connected to the first—exactly two (2) neighbors for each device.

• Star Topology

• Network Topologies

• Ring Topology

• Bus Topology

has a root node and all other nodes are connected to it forming a hierarchy. It is also called hierarchical topology

• Tree Topology

• Full Mesh Topology

• Mesh Topology

• Partial Mesh Topology

a point-to-point connection to other nodes or devices. All the network nodes are connected

• Tree Topology

• Full Mesh Topology

• Mesh Topology

• Partial Mesh Topology

in this topology, some systems are connected in the same fashion as mesh topology, but some devices are only connected to two (2) or three (3) devices.

• Tree Topology

• Full Mesh Topology

• Mesh Topology

• Partial Mesh Topology

each node or device is connected.

• Tree Topology

• Full Mesh Topology

• Mesh Topology

• Partial Mesh Topology

it consists of a mix of two (2) different types of topologies merging as one network.

• Tree Topology

• Hybrid Topology

• Mesh Topology

• Partial Mesh Topology

It is the end-device of the data communication system. It provides the necessary functions required by the user access protocol operations.

• Firewall

• Router

• Terminal Device

• Switch
