Arcade machines, a staple of gaming culture, rely on various networking protocols to ensure smooth multiplayer experiences, online connectivity, and system updates. The most common protocols include:

1. TCP/IP (Transmission Control Protocol/Internet Protocol)

- Ensures reliable data transmission between arcade machines and servers.

- Used for online leaderboards, firmware updates, and multiplayer synchronization.

2. UDP (User Datagram Protocol)

- Favored for real-time gameplay due to lower latency.

- Ideal for fast-paced arcade games where speed outweighs packet loss.

3. HTTP/HTTPS

- Facilitates secure communication for online features like score submissions and game downloads.

4. Proprietary Protocols

- Some arcade manufacturers develop custom protocols for specialized hardware or security.

These protocols ensure arcade machines remain connected, competitive, and up-to-date in the modern gaming landscape.
