netcode

Netcode is a blanket term most commonly used by gamers relating to networking in online games, often referring to synchronization issues between clients and servers. Players often infer "bad netcodes" when they experience lag or when their inputs are dropped. Common causes of such issues include high latency between server and client, packet loss, network congestion, and external factors independent to network quality such as frame rendering time or inconsistent frame rates. Netcodes may be designed to uphold a synchronous and seamless experience between users despite these networking challenges.
