सही: ० / ०
-
The correct order of the basic instruction (machine) cycle is:
सही उत्तर: ख) fetch, decode, execute
The CPU first fetches the instruction from memory, decodes it, then executes it.

-
In many simple CPUs, the register that holds one operand for the ALU and receives its result is called the:
सही उत्तर: क) Accumulator
The accumulator is the default working register for arithmetic and logic operations.

-
The Instruction Register (IR) in a CPU holds:
सही उत्तर: क) the instruction currently being decoded and executed
After a fetch, the instruction is placed in the IR so the control unit can decode and execute it.

-
The CPU register that temporarily holds data just read from memory or about to be written to memory is the:
सही उत्तर: ख) Memory Data (Buffer) Register
The MDR (also called MBR) buffers data moving between the CPU and memory.

-
Which CPU register holds the address of the memory location that is to be read or written?
सही उत्तर: क) Memory Address Register (MAR)
The MAR holds the address sent on the address bus for the current memory access.

-
How many distinct Boolean functions are possible with 2 input variables?
सही उत्तर: ख) 16
There are 2^2 = 4 input rows, each with an output of 0 or 1, giving 2^4 = 16 functions.

-
Shifting an unsigned binary number one position to the left (filling 0 on the right) is equivalent to:
सही उत्तर: घ) multiplying it by 2
Each left shift moves every bit to the next higher power of 2, doubling the value (if no bits are lost).
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A shift register that receives data one bit at a time and makes all bits available at once is called:
सही उत्तर: घ) Serial-in parallel-out (SIPO)
Data enters serially and is read out from all stages simultaneously, i.e. serial-in parallel-out.

-
In an asynchronous (ripple) counter:
सही उत्तर: ग) each flip-flop after the first is clocked by the output of the previous stage
In a ripple counter the clock ripples through the stages, each flip-flop being triggered by the previous one's output.

-
The minimum number of flip-flops needed for a mod-10 (decade) counter is:
सही उत्तर: ग) 4
3 flip-flops give only 8 states; 4 flip-flops give 16 states, enough for 10.
