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.
Answer: Option C
Solution (By JKExamLibrary)
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.
Explanation:
A memory scheduler in a memory controller reorders incoming read/write requests to optimize bandwidth and reduce latency, improving overall performance.
Explanation:
L1 cache is built with SRAM because it is extremely fast and has low latency, matching the CPU speed, even though it is expensive and small.
