Data routing is the process of selecting paths in a network along which to send data packets. It involves directing data from its source to its destination through various devices, such as routers and switches. These devices analyze the data's destination address and determine the most efficient route, ensuring that information reaches its intended endpoint quickly and accurately. Effective data routing is crucial for maintaining network performance and reliability. It helps manage traffic loads, reduces congestion, and minimizes delays. By optimizing the flow of data, routing enhances the overall user experience in applications like internet browsing, video streaming, and online gaming.
