A switch would be the best network device to use in a corporate environment to connect PCs and a printer to one another in a wired LAN. A switch is a networking hardware device that connects devices together on a network by using packet switching to forward data to its destination. Switches are scalable, can handle high bandwidth, and allow for efficient communication between the connected devices. They also provide security and can prioritize network traffic, ensuring critical data transmissions get through smoothly while minimizing network congestion.
