Radio Resource Control (RRC): The layer in mobile networks responsible for controlling the radio resources between the mobile device and the base station.
Analogy: Like a stage manager for a play, it manages the stage (radio resources) and coordinates with the actors (mobile devices and network) to ensure a smooth performance.
Why It Matters: RRC ensures that radio resources are used efficiently, that mobile devices can connect to the network, and that data can be transmitted reliably.
