Network Components are essential for setting up and optimizing computer networks. These include routers, modems, switches, hubs, network cables, and Wi-Fi extenders. Routers connect local networks to the internet, while modems convert data for use by your network. Switches and hubs allow multiple devices to connect within the network, with switches offering more efficient data management. Network cables ensure stable connections, and Wi-Fi extenders improve wireless coverage. Choosing the right network components is crucial for maintaining a fast, reliable, and secure network.
