ITPEC IP April 2025 Question 18
ITPEC IP April 2025 — Question 18 of 100
BIOS, OS, resident application programs — startup proceeds from firmware to the operating platform and finally to applications.
Immediately after power-on, the BIOS or equivalent firmware initializes and checks hardware, then locates and starts the operating system. Once the OS has loaded the services needed to run programs, applications configured to remain resident can start.
Answer (a)
Why not others:
- (b) places the OS before the firmware that starts the boot process
- (c) also puts the BIOS last, although it must initialize the machine first
- (d) puts applications before both the firmware and OS services on which they depend
Key rule: Boot dependencies determine order: firmware initializes hardware, the boot process loads the OS, and the OS then launches startup applications.
