Evolution of Operating Systems: A Timeline Exploration

Dive into the timeline of the universe and the digital universe, focusing on the first few seconds of system boot-up processes from power-on to app launch. Understand the crucial roles of BIOS, UEFI, and the OS in the sequence of events. Explore how CPU instructions are stored, when BIOS/UEFI hands over to the OS, and the initial apps that run. Discover if BIOS/UEFI remains active and the impact of running apps like email and browsing before full OS boot. Resources provided for a comprehensive class assignment.

  3. The first few seconds of the (Digital) Universe • Power On  POST  BIOS  OS  Apps • Revised! • Power On  POST  UEFI (EFI)  OS  Apps

  4. Class assignment (Now!) • The first few seconds: • What happens first? • CPU’s first instructions—Where/how stored? • What does BIOS/UEFI do? • When does BIOS/UEFI hand over to OS • Is the BIOS/UEFI completely inactive? • What does the OS boot-up do? • What are the first Apps in the OS to run? • What about running email and browsing before the OS boots? • How long does each stage take?
