Which of the following would BEST describe the capabilities of a 64-bit operating system?

The correct answer is D. Capable of utilizing 128GB RAM. A 64-bit operating system can address vastly more memory than a 32-bit system, which is capped at approximately 4GB of RAM.

Why each option

A 64-bit operating system can address vastly more memory than a 32-bit system, which is capped at approximately 4GB of RAM.

ACapable of managing dual NICs.

The ability to manage dual NICs is a function of available drivers and expansion slots, not the CPU or OS bit-width.

BCapable of effectively managing 1TB SSD.

Storage capacity management for a 1TB SSD is handled by the storage controller and file system, not determined by the OS bit-width.

CCapable of managing more than 4 displays.

Support for multiple displays is governed by the GPU and display drivers, not the 32-bit versus 64-bit distinction of the OS.

DCapable of utilizing 128GB RAM.Correct

A 64-bit OS uses 64-bit memory addressing, allowing it to theoretically address up to 16 exabytes of RAM. In practice, Windows 64-bit editions support up to 128GB or more depending on the edition, far exceeding the 4GB physical limit of a 32-bit OS. This expanded addressable memory space is the defining functional advantage of a 64-bit architecture.
