The Boot Process, Chapter 6

When you first power on the PC, what is the first step?

• a. The Power Supply circuitry checks for proper voltage.

• a. The CPU awakens and responds to all requests from the MCC.

• a. All information from DRAM is re-obtained onto the computer's hard drive.

• a. The LED, located in front of the computer chassis, illuminates.

What is the second step in powering on the PC?

• b. The MCC connects to the CPU, there in which its responsibility of data-exchange between memory and the CPU begins.

• b. DRAM powers on and its spreadsheet-like structure expands in size five score and two.

• b. It sends a signal down the Power Good wire to awaken the CPU.

• b. The signal of the system ROM is sent and obtained by the CPU, where it then recollects volatile data.

Step #2: The CPU:

• a. The Power Supply Unit begins using voltage.

• a. Awakens and immediately sends a built-in memory address via the address bus.

• a. Video RAM (VRAM) begins processing and tracks the computer's frames per second.

• a. The Memory Controller Chip (MCC) begins taking requests from the Central Processing Unit (CPU).

Step #2B: The CPU...

• Free Slot: One Less Answer Choice! :)

  (This answer choice is incorrect)

• b. The chipset ignores System ROM's volatility, shortly after the Peripheral Component Interconnect Express (PCIe) synchronizes to the computer's System Crystal (Quartz Oscillator).

• b. The computer begins its Power On Self Test, shortly after electricity in the Power Supply Unit (PSU).

• b. The address is the first line of POST on the System ROM.

Step #3: The system starts...

• a. The POST runs.

• a. POST ends.

• a. POST activates the CPU.

• a. The POST activates volatility.

OS loading in UEFI systems... (step a.)

• a. UEFI, the Unreal Editor for Fortnite, activates.

• a. macOS Ventura activates UEFI, as it does not have an integrated Basic Input/Output System.

• a. Windows 10 does not load until the user has moved past CMOS.

• a. POST hands control of the boot process to the boot manager.

OS loading in UEFI systems... (step b.)

• b. Boot managers checks Boot config. and loads the OS Boot Loader.

• b. The OS creates an involatile QR-code like information-retainer used for device-scanning, shortly after the Boot Process activates BIOS.

• b. The Application Programming Interface (API) activates and loads for all applications installed onto the Windows computer and provided by the Windows Operating System.

• b. The computer's operating system temporarily transforms into one that is 32-bit, to process smaller bits of information, mainly used for storing files, selecting file-types, and choosing file sizes.

OS loading in older BIOS environment... (step a.)

• a. POST "walks" to the Recycling Bin and closes all unnecessary running programs.

• a. Post passes control to the Boot-Strap loader.

• Free-Slot

  One less answer choice to worry about :)

  (This choice is incorrect.)

• Free-Slot

  One less answer choice to worry about :)

  (This choice is incorrect.)

OS loading in older BIOS environment... (step b.)

• b. The POST heads to its office, where it prepares to send all mail set as scheduled.

• b. POST goes through a phase known as "medium," where it activates SDRAM to enable 77% of the operating system's tasks.

• b. The Boot-Strap Loader reads CMOS to find out where the OS is (using Boot sequence).

• b. 25 of 30 processing chips found on the Northbridge shut down to make room for more storage-consuming tasks created by the Windows operating system.

• b. The Complementary Metal-Oxide Semiconductor gains 7 electrons and loses 3 protons after the Operating System powers on.

OS loading in older BIOS environment... (step c.)

• c. Good luck on your Boot Process Quiz!

  You got this!

  (This answer is not a correct choice.)

• c. Control is passed to the OS and the Boot strap loader is removed from memory.
