What feature allows modern computer memory controllers to access two independent memory modules simultaneously, effectively doubling the standard data transfer bandwidth? MCQ with Answer and Explanation
What feature allows modern computer memory controllers to access two independent memory modules simultaneously, effectively doubling the standard data transfer bandwidth?
A. Hyper-threading
B. ECC Error Correction
C. Dual-Channel Architecture
D. Direct Memory Access
Answer: Option C
Solution (By JKSSB Mock Tests)
Dual-channel architecture introduces two independent memory bus pathways, allowing the controller to communicate with two RAM sticks concurrently to increase data throughput.
Explanation:
CAS (Column Address Strobe) latency is a measure of the delay between a memory read command and the availability of data, indicating memory speed. Capacity is size, voltage is power, and pins are physical connector.
Explanation:
Cache memory is a small, fast memory located close to the CPU that stores copies of frequently accessed data from main memory to reduce average access time.
