In this activity, "Introduction to Networking," I explored the basics of computer networks, including their types, components, and how different devices interact within these networks. A computer network is essentially a system in which multiple computers are interconnected to share information and resources. Key types of networks include Local Area Networks (LANs), which connect devices within a small, confined space, and Wide Area Networks (WANs), which span larger geographical areas. The course also highlighted intranets, which are private organizational networks, and extranets, which extend this access to trusted external partners. These types of networks, along with the different models such as peer-to-peer and server-based, provide a fundamental understanding of how modern communication systems operate.
In addition to understanding the types of networks, I also studied network components and topologies, which included crucial devices like routers, switches, and wireless access points (WAPs). Routers are used to direct data between networks using IP addresses, while switches connect devices within a LAN using MAC addresses to ensure data reaches the correct destination. WAPs allow wireless devices to connect to a wired network, providing both centralized control and expanded coverage. I also learned about the different types of network topologies, including star, bus, ring, and hybrid topologies, which define how network nodes are arranged and connected. This understanding of network components and topologies will be extremely useful in troubleshooting connectivity issues or designing networks, both in home environments and potential future professional settings.
The activity also delved into the OSI Model, which provides a layered framework for understanding network interactions. The OSI Model consists of seven layers, each with distinct roles: the Physical, Data Link, Network, Transport, Session, Presentation, and Application layers. These layers ensure that data is transmitted efficiently and securely, while allowing each layer to work independently. This modular approach is particularly helpful in understanding how different network functions are managed, from establishing connections (Session Layer) to error-free data transfer (Transport Layer). I envision applying the OSI Model in my future projects to systematically identify and address network issues, ensuring efficient data flow within networks and improving overall network management.
