Which memory type serves as the fast, specialized storage space for storing translation mappings between virtual and physical memory addresses? MCQ with Answer and Explanation

Which memory type serves as the fast, specialized storage space for storing translation mappings between virtual and physical memory addresses?
A. EPROM
B. Virtual Page File
C. Hard Disk MBR
D. Translation Lookaside Buffer (TLB)
Answer: Option D
Solution (By JKExamLibrary)
The TLB is a dedicated hardware memory cache within the CPU's memory management unit (MMU) that speeds up virtual-to-physical address translations.

Question #2
What is the typical data transfer rate of a USB 3.0 flash drive?
A. 10 Gbps
B. 480 Mbps
C. 5 Gbps (theoretical)
D. 1 Gbps

Correct Answer: Option C


Explanation:
USB 3.0 has a theoretical maximum data rate of 5 Gbps. Actual throughput is lower, but it's significantly faster than USB 2.0 (480 Mbps).

Question #3
What characteristic of a computer system is optimized when a designer adds more channels to the main system memory bus layout?
A. The maximum capacity of the secondary storage drives.
B. The resolution of the external monitor display.
C. The system memory bandwidth and data throughput rates.
D. The permanent storage durability of the ROM firmware.

Correct Answer: Option C


Explanation:
Adding more memory channels increases the width of the data bus between the CPU and RAM, allowing more data bits to transfer simultaneously and boosting system memory bandwidth.
