Final answer:
Option D: Smaller page tables are implemented as a set of registers to improve system efficiency by allowing quicker memory lookups and minimizing the size of page tables stored in memory.
Step-by-step explanation:
Smaller page tables are implemented as a set of registers. In computer architecture, when dealing with memory management and virtual address translation, page tables are essential. These page tables map virtual addresses to physical addresses and are stored in memory. To improve the speed of memory access and minimize the size of page tables, portions of these tables can be stored in high-speed storage, which in this context are referred to as registers.
Registers are quick storage locations within the CPU that enable the rapid retrieval and manipulation of data. By utilizing registers for smaller page tables, the efficiency of the system is improved due to the reduced time needed for memory lookups. This is critical for the effective functioning of modern computer systems, where time and resources are essential for maintaining system performance and stability.
