Network TopologyDefinition and Types
Definition of Network Topology
Network Topology is the layout pattern of interconnections of the various elements of a computer or biological network. And it is of two(2) types; Physical and Logical.
Physical Topology: refers to the physical design of a network including the devices, locations and cable installation
Logical Topology: refers to how data is actually transferred in a network as opposed to its physical design.
Bus topology
A bus network topology is a network architecture in which sets of clients are connected via a shared communications line, called a bus.

Star Topology
Star network topology is the most common computer network topology.
A star network consist of one central switch, hub or computer, which acts as a conduit to transmit messages

Mesh Topology
Mesh topology is a type of networking where each node must not only capture and disseminate its own data, but also serve as a relay for other nodes, i.e it must collaborate to propagate the data in the network

Ring Topology
Ring topology is a network topology in which each node connects to exactly two or other nodes, forming a single continuous pathway for signals through each node-a ring

Repeater
RouterForwards data packets between computer networks.
Creats overlay internetwork.
Traffic directing
GatewayA gateway is a combination of hardware and software
Translate between different protocol suites
Operates on all 7 layers of the OSI model
SwitchReceives and transmit messages to other devices on the network
Operate at one or more layers of the OSI model
BridgeEthernet networks use transparent bridges
Token Ring networks use source-routing bridges Translation Bridges
RepeaterAn analog device that amplifies an input signal regardless of its nature
Operates on the physical layer, the 1st layer of the OSI model
