Network protocols are sets of rules that govern how data is transmitted and received between devices. They include TCP (Transmission Control Protocol), which ensures reliable data transmission, and UDP (User Datagram Protocol), which is faster but less reliable. Understanding these protocols is important for developing a smooth and stable multiplayer experience.

3. Synchronization and Interpolation:

Synchronization is the process of ensuring that all players see the same game state at the same time, while interpolation is the process of smoothing out movement and animation to make it appear more fluid. These processes are critical for creating a seamless multiplayer experience and avoiding issues such as lag and desynchronization.

Understanding these basic concepts is crucial for creating a successful multiplayer game in Unity. With this foundation in place, developers can begin to explore the technical aspects of multiplayer game development in Unity.
