Personal computers with two LAN ports

2 LAN ports

— the case features two Ethernet ports so that the PC can operate on two wired networks simultaneously or manage two communication lines. Such a computer is convenient when you need to separate office/home and work/guest networks without extra adapters, connect a separate NAS/storage server directly, or reserve one port for the internet and the other for a local network with devices like a printer, surveillance camera, and media server. Two LAN ports are often chosen for mini servers, home servers, workstations with large data volumes, and PCs for virtualization because they allow for redundancy setup (if one cable/router fails, the connection remains) or link aggregation for higher bandwidth if supported by network equipment. Example usage: one cable goes to a router with internet, and the second to a separate switch for devices in the workshop; or the PC is simultaneously connected to a home network and a closed office network through a separate router/firewall.
