Networks and infrastructure serve as the backbone of modern connectivity, facilitating the flow of data across various devices, systems, and geographical locations. Whether it's a multinational corporation managing its global operations, a healthcare provider transmitting patient records securely, or an individual streaming videos on their smartphone, all rely on a solid network foundation.

At its core, network infrastructure encompasses hardware components such as routers, switches, servers, cables, and data centers. These components are interconnected through a series of protocols and technologies, including TCP/IP, Ethernet, VPNs, and Wi-Fi, among others. Together, they form the underlying framework enabling data transmission and communication.
