Topology
Network topology
The physical configuration of a network that determines how the network's computers are connected. Common configurations include the bus topology, mesh topology, ring topology, star topology, and tree topology.

Bus topology
This is where everything is connected to a one way cable and if one thing goes down the whole thing breaks.
Mesh topology
Is where every computer is interconnected with each other. Allowing for most transmissions to be distributed, even if one of the connections go down. This is very expensive so is not used often
Ring topology
This is when all computers are connected with the computer next to them making a ring a message is sent around the ring till it reaches the right computer.
Star topology
This is the most commonly used network. Each devise is connected to a central hub. There is a problem with this set up. If the hub goes down then the whole network goes down.
Tree topology
Alternatively referred to as a star bus topology, tree topology is one of the most common network setups that is similar to a bus topology and a star topology. A tree topology connects multiple star networks to other star networks.
A HUB, a SWITCH, and a ROUTER
An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment. It has multiple input/output (I/O) ports, in which a signal introduced at the input of any port appears at the output of every port except the original incoming. A hub works at the physical layer of the OSI model. The device is a form of multiport repeater.
A network switch (sometimes known as a switching hub) is a computer networking device that is used to connect devices together on a computer network. A switch is considered more advanced than a hub because a switch will only send a message to the device that needs or requests it, rather than broadcasting the same message out of each of its ports.
A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Routers perform the "traffic directing" functions on the Internet.
