What is the primary role of the address bus in a computer's memory architecture?
A. To supply electrical voltage to the dynamic memory refresh circuits.
B. To regulate the processing clock speed of the graphics adapter.
C. To transfer the actual data payload bits between components.
D. To communicate the physical memory location coordinate being targeted for read or write.
Answer: Option D
Solution (By JKSSB Mock Tests)
The address bus is a directional pathway used exclusively by the CPU to point to the specific hardware memory address location it wants to interact with.
Explanation:
For DDR memory, the effective data rate is often quoted in MT/s (megatransfers per second), which indicates the number of data transfers per second. MHz is clock frequency, which is half of MT/s for DDR.
Explanation:
Firmware (like BIOS) is stored in ROM (or flash memory) because it is non-volatile and retains data without power, and is not meant to be frequently changed.
Explanation:
TBW (Terabytes Written) is an endurance metric that specifies the total cumulative amount of data an SSD can safely write before flash memory cell degradation risk increases.
