1. ACPI vs UEFI

ACPI (Advanced Configuration and Power Interface) and UEFI (Unified Extensible Firmware Interface) are both important standards in modern computer systems, but they serve different purposes.

ACPI is a power management and configuration interface specification for hardware and operating systems. It defines various aspects of system configuration, including power states, device enumeration, and resource allocation. ACPI is typically implemented in the firmware (BIOS or UEFI) of a computer system and provides a standardized way for the operating system to interact with hardware components.

UEFI, on the other hand, is a replacement for the traditional BIOS (Basic Input/Output System) firmware interface. It provides more advanced features than BIOS, including support for larger hard drives, faster boot times, a modular architecture, and support for modern security features like Secure Boot. UEFI serves as the interface between the operating system and the firmware, providing a standardized way f
