Connected arcade game machines rely on various networking protocols to enable multiplayer gaming, online leaderboards, and remote management. The most common types include TCP/IP for reliable data transmission, ensuring stable connections in games requiring consistent data flow. UDP is often used for real-time multiplayer interactions due to its low latency, though it may sacrifice some reliability. Ethernet protocols provide wired connectivity for high-speed data transfer in arcade cabinets, while Wi-Fi supports wireless setups in modern arcades. These protocols facilitate features like global score tracking, firmware updates, and social integration, enhancing the player experience in digital entertainment venues.
