2. Introduction to Computer Networks Definition: A computer network is a group of interconnected computers that share resources and communicate with each other. Purpose: Enables resource sharing, data exchange, and communication across multiple devices. Define computer network. Discuss various types of network topologies in computer network. also discuss various advantages and disadvantage of each topology.

3. Types of Network Topologies Overview: Network topology refers to the arrangement of elements (links, nodes, etc.) in a computer network. Common Types: Bus Topology Star Topology Ring Topology Mesh Topology Tree Topology

4. Bus Topology Structure: All devices are connected to a single central cable (the bus). Advantages: Simple to set up. Requires less cable than other topologies. Cost-effective for small networks. Disadvantages: Difficult to troubleshoot. A break in the central cable can cause network failure. Limited cable length and number of devices.

5. Star Topology Structure: All devices are connected to a central hub or switch. Advantages: Easy to install and manage. Failure of one device doesn’t affect the network. Easy to add or remove devices. Disadvantages: Expensive due to the cost of the hub. Hub failure can bring down the entire network. More cable is required compared to bus topology.

6. Ring Topology Structure: Devices are connected in a circular fashion, with each device connected to two other devices. Advantages: Data transmission is relatively straightforward. Can perform better than a bus topology under heavy load. Disadvantages: A failure in any cable or device disrupts the entire network. Troubleshooting is difficult. Adding or removing devices can cause network downtime.
