Data Communication
Data communication is the process of transmitting digital data between two or more devices over a communication channel, such as wired or wireless networks. It involves protocols, standards, and technologies that enable reliable and efficient exchange of information, forming the foundation of modern networking and internet systems. This concept encompasses everything from low-level signal transmission to high-level application data exchange.
Developers should understand data communication to build networked applications, optimize performance, and troubleshoot connectivity issues in distributed systems. It's essential for roles involving web development, IoT, cloud computing, and any software that relies on network interactions, as it underpins how data flows between clients, servers, and devices.
