Answer 1

The command that can be used to gather information about the CPU found during boot is: 2. cat /proc/cpuinfo | grep CPU

What is this command

This command reads the CPU-related information from the "/proc/cpuinfo" file and filters the output using "grep" to display details related to the CPU.

The command cat /proc/cpuinfo is used to display the contents of the /proc/cpuinfo file in the terminal. This file includes information such as CPU type, model, number of cores, cache size, flags, and more for each CPU core present in the system.
