Which two statement describe the functions or characteristics of ROM in a router?

ROM (Read-Only Memory) in a router stores the firmware or the basic operating system required for the router to boot up and perform essential functions. It contains the router's initial instructions and diagnostics, which are crucial for hardware initialization and running the system software. Unlike RAM, the data in ROM is not volatile, meaning it remains intact even when the router is powered off. Additionally, ROM can store bootloader programs and configuration settings that are necessary for the router's operation.
