THE DEFINITION OF DATA COMMUNICATION

In this module, students will be introduced to the fundamentals of data communication, which involves the exchange of data between devices over a communication medium. Key components include the sender, receiver, medium, message, and protocol. Students will explore: • The distinction between analog and digital data. • The OSI Model and TCP/IP Model, which guide how data communication occurs in layered structures. • Data flow types: Simplex (one-way), Half-Duplex (two-way, but not simultaneously), and Full-Duplex (two-way simultaneously). The module provides foundational knowledge that prepares students for understanding more complex data communication concepts and systems.
