Question
You are reviewing the history of the original 8088 processor with a new technician in your department. As a computer starts and goes through its startup routine, the CPU is in a state called “real mode” up to the boot loader phase of the startup, when it changes to “protected mode.” What are some characteristics of a CPU running in protected mode? (Choose two.)
A. In protected mode, a CPU can access memory up to 1 MB.
B. In protected mode, a CPU can support multitasking.
C. In protected mode, a CPU can support virtual memory.
D. In protected mode, a CPU can read the BIOS.
Explanation / Answer
B and C. Once a CPU is in protected mode, a CPU can access memory above 1 MB, support multitasking and virtual memory, and run each application on the computer in its own memory space, protecting that space from being used by any other application on the computer.
