This document outlines the essential concepts of computer networking, including the roles of clients and servers, networking protocols, and various network topologies. Key topics discussed include the functions and communication methods of networking media, the importance of network protocols in data transmission, and different configurations such as star, ring, mesh, bus, line, and tree topologies. The document serves as a learning module for students to develop a comprehensive understanding of these networking principles.

- 2. Learning Competencies At the end of this learning module the students will be able to . . . ○ Discuss the client and servers functions in computer networking. ○ Understand the concept of Network Protocol ○ Enumerate and classify computer networking topologies.
- 3. Networking Media Networking media can be defined simply as the means by which signals (data) are sent from one computer to another (either by cable or wireless means). INSIDE THE ETHERNET CABLE
- 4. CLIENT AND SERVER In a client/server network arrangement, network services are located in a dedicated computer whose only function is to respond to the requests of clients. The server contains the file, print, application, security, and other services in a central computer that is continuously available to respond to client requests.
- 5. NETWORKING PROTOCOL (TCP/IP) Network protocols are formal standards and policies comprised of rules, procedures and formats that define communication between two or more devices over a network. Network protocols govern the end-to-end processes of timely, secure and managed data or network communication.
- 6. PROTOCOL CONCEPTS ○ Set of rules ○ What do you want to do? (Application) ○ Where are you going? (Addressing) ○ How do you get there? (Media Types) ○ Did you get there? (Error Checking)
- 7. Computer Networking Models Models, also called protocol stacks, represented in layers, help to understand where things go right or wrong.
- 8. Network Topologies Network Topology refers to the shape of a network, or the network's layout. How different nodes in a network are connected to each other and how they communicate are determined by the network's topology.
- 9. RING TOPOLOGY All the nodes are connected to each-other in such a way that they make a closed loop. Each workstation is connected to two other components on either side, and it communicates with these two adjacent neighbors.
- 10. STAR TOPOLOGY The most commonly used network topology. All the network nodes are individually connected to a central switch, hub or computer which acts as a central point of communication to pass on the messages.
- 11. STAR TOPOLOGY The most commonly used network topology. All the network nodes are individually connected to a central switch, hub or computer which acts as a central point of communication to pass on the messages.
- 12. FULLY CONNECTED / MESH TOPOLOGY All the network nodes are connected with one another to perform data communication. Every computer in the network has a connection to each of the other computers in that network.
- 13. BUS TOPOLOGY is a network setup in which each computer and network device are connected to a single cable or backbone.
- 14. LINE TOPOLOGY In this system, data is sent to all nodes on the network at the same time. Devices are positioned along a line.
- 15. TREE TOPOLOGY it is a combination of two or more star networks connected together. Each star network is a local area network (LAN) in which there is a central computer or server to which all the workstation nodes are directly linked.
