What process is initiated by the router's bootstrap code stored in ROM?

The process initiated by the router's bootstrap code stored in ROM is the Power-On Self Test (POST). This is a diagnostic procedure that occurs during the boot-up sequence of the router. When the device is powered on, the bootstrap code runs the POST to check the hardware components of the router, such as the CPU, memory, and interfaces, to ensure they are functioning correctly. This step is crucial as it identifies any potential hardware failures before the device attempts to load the operating system.

This initial self-test is essential for proper operation of the router, as it helps prevent the router from running with defective hardware, which could lead to suboptimal performance or failures in routing data. After the POST is completed successfully, the router can then proceed to load the operating system and continue with the boot process, including other initialization tasks necessary for operation.
