Hubs and switches are essential components in networking environments, primarily used to connect multiple devices together within a local area network (LAN). A hub is a basic networking device that transmits data packets between connected devices, but it does so indiscriminately, broadcasting the data to all ports, which can lead to collisions and network inefficiency. In contrast, a switch is more advanced; it not only connects devices but also manages the data traffic more efficiently by sending data only to the intended recipient device. This not only enhances security by reducing the chances of data interception but also improves network performance by minimizing unnecessary traffic. Both hubs and switches are fundamental in creating interconnected networks, facilitating communication and data sharing across computers, printers, and other network-enabled devices.
