Networking refers to the practice of connecting multiple computing devices, such as computers, servers, and network switches, enabling them to communicate and share resources. These connections can be made via wired cables like Ethernet or wirelessly through Wi-Fi, allowing data, software, and hardware to be shared across the network. Networking can happen on a small scale, often referred to as a Local Area Network (LAN), within a single location, or it can span across great distances, creating a Wide Area Network (WAN). The Internet itself is a form of a global network, allowing computers from around the world to communicate with each other. Network configurations can serve various purposes, from sharing files and printers in an office to enabling complex, distributed computing environments that power large-scale web services. As cybersecurity concerns have grown, the field of networking has also evolved to include the study and implementation of security protocols to protect data as it traverses these networks. Computer networking plays a critical role in modern-day communication, business operations, and access to information.
