Data networking refers to the practice of connecting computers and other devices to share information and resources. This connection can be established through various means, such as wired cables or wireless signals. The primary goal of data networking is to enable communication between devices, allowing users to access files, applications, and the internet efficiently. In a data network, devices are often organized into structures like local area networks (LANs) or wide area networks (WANs). Networking equipment, such as routers and switches, plays a crucial role in directing data traffic and ensuring that information reaches its intended destination. This interconnected system is essential for modern communication and collaboration.
