Communication protocols

Definition

Communication protocols are sets of rules and conventions that determine how data is transmitted and received over a network. They ensure that devices can understand each other and communicate effectively, facilitating the exchange of information in systems like power electronics and smart grids. These protocols govern various aspects such as data format, timing, error handling, and synchronization, which are crucial for reliable operations in complex electrical environments.
