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.

-
When a CALL instruction transfers control to a subroutine, the return address is normally saved on the:
सही उत्तर: क) stack
The return address is pushed onto the stack and popped back into the program counter by the RET instruction.
