Data Formats

Communication Protocols: The Language of Digital Systems In tech, devices and apps talk through protocols. A protocol is a shared set of rules for exchanging messages, agreeing on data formats, timing, and error handling. When both sides follow the same rules, conversation is reliable and predictable. Most systems use layered models. A lower layer handles transport, while higher layers define how information is structured and understood. This separation makes it easier to swap parts without rebuilding everything. ...

Communication Protocols Under the Microscope Protocols are the rules that devices use to talk with each other. They shape how messages are built, how they travel, and how to handle mistakes. When you pick a protocol, you weigh speed, security, and how easy it is to use in real projects. A clear choice helps apps stay reliable and friendly for users. Most protocols work in layers. The transport layer moves data from one device to another, while the application layer explains what the data means and how actions should happen. Some protocols are very fast and light, so they work well on small devices. Others offer more features, but send bigger messages and need more power and bandwidth. ...
