 ##Networking
 ###8 - Research the following methods (*topologies*) for connecting devices to a network. In each case give a description and at least 1 advantage and 1 disadvantage.
 
 **Bus Topology (6 marks)**
 ```
-Describe:
+Describe:A bus network is a network topology in which nodes are connected in a daisy chain by a linear sequence of buses.
 
-Advantages:
 
+
+Advantages:
+It works well for small networks.
 Disadvantages:
+Entire network shuts down if there is a break in the main cable
 ```
 
 **Ring Topology (6 marks)**
 ```
-Describe:
+Describe:A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. Data travel from node to node, with each node along the way handling every packet.
 
-Advantages:
+Advantages:Very orderly network where every device has access to the token and the opportunity to transmit
 
-Disadvantages:
+Disadvantages:Communication delay is directly proportional to number of nodes in the network
 ```
 
 **Star Topology (6 marks)**
 ```
-Describe:
+Describe:Star networks are one of the most common computer network topologies.
 
-Advantages:
+Advantages:star topology prevents the passing of data packets through an excessive number of nodes. At most, 3 devices and 2 links are involved in any communication between any two devices. Although this topology places a huge overhead on the central hub, with adequate capacity, the hub very high utilization by one device without affecting others.
 
-Disadvantages:
+
+Disadvantages:Failure of the central hub renders the network inoperable
