Network engineering is the field of designing, building, and managing computer networks. It involves creating and maintaining the infrastructure that allows devices like computers, servers, and smartphones to communicate with each other and share information.
In simpler terms, network engineering is like constructing a system of roads and highways that connect different places. The network engineer is responsible for planning the routes, setting up the necessary equipment such as routers and switches, and ensuring that the traffic flows smoothly and securely.
Network engineers work with various technologies such as Ethernet, Wi-Fi, and the Internet to establish reliable and efficient connections. They configure network devices, troubleshoot issues, and optimize performance to ensure that data can travel quickly and securely between different devices and locations.
