A2.3 Data transmissions

This section introduces key concepts related to how data is transmitted across networks, with a focus on addressing, transmission media, and routing methods. Students will learn about different types of IP addressing, compare physical and wireless transmission media, and explain how data is efficiently sent using packet switching. Higher-level students will also explore how static and dynamic routing techniques are used to move data across local area networks, gaining insight into how modern networks are structured for reliability and performance.
