In layman's terms:
APIC: a chip that helps interrupt routing -- addresses the historic
problem with x86 PCs only having 16 IRQs (extends this to 256)
ACPI: system capabilities interface -- defines different aspects of your
computer, and ties different pieces together. Also acts as an interface
to power-related features often used on laptops (not to be confused with
S1/S3 suspend states)
