Which type of flash memory, offering high density at low cost, is mainly used for mass storage in SSDs, memory cards and USB drives?
सही उत्तर: ग) NAND flash
NAND flash packs cells densely and is ideal for block storage, while NOR flash is used where fast random reads of code are needed.

A 64-bit wide data bus transfers one word per clock cycle at 100 MHz. Its peak transfer rate is:
सही उत्तर: ग) 800 MB/s
64 bits = 8 bytes per transfer; 8 bytes x 100 million transfers per second = 800 MB/s.

A processor's base clock (bus) frequency is 100 MHz and its clock multiplier is 36. Its core clock speed is:
सही उत्तर: ख) 3.6 GHz
Core speed = base clock x multiplier = 100 MHz x 36 = 3600 MHz = 3.6 GHz.

-
Thermal paste is applied between a CPU and its heat sink in order to:
सही उत्तर: घ) fill microscopic air gaps and improve heat conduction
Air is a poor conductor of heat, so thermal compound fills tiny gaps to help heat flow from the CPU to the heat sink.
