In register indirect addressing mode:
सही उत्तर: क) a register holds the memory address of the operand
In register indirect mode the register contains the address, and the operand is fetched from that memory location.

A superscalar processor is one that:
सही उत्तर: घ) can issue and execute more than one instruction per clock cycle
Superscalar CPUs have multiple execution units and dispatch several instructions in each cycle.

A GPU (Graphics Processing Unit) is especially suited to:
सही उत्तर: क) performing many simple calculations in parallel, such as graphics rendering
GPUs contain hundreds or thousands of small cores for highly parallel tasks like graphics and machine learning.

-
A multi-core processor is one that:
सही उत्तर: ग) has two or more independent processing units on a single chip
Each core can execute instructions independently, allowing true parallel execution on one chip.

-
The routine that the CPU executes in response to an interrupt is called the:
सही उत्तर: ग) Interrupt Service Routine (ISR)
When an interrupt occurs, the CPU saves its state and jumps to the ISR that handles that interrupt.

In memory-mapped I/O:
सही उत्तर: ख) I/O devices share the memory address space and are accessed with ordinary memory instructions
Memory-mapped I/O assigns device registers to memory addresses, so normal load/store instructions access them.

The Intel 8086 microprocessor has a 20-bit address bus. The maximum memory it can address is:
सही उत्तर: क) 1 MB
2^20 = 1,048,576 locations = 1 MB.

-
The Intel 8085 is a/an:
सही उत्तर: घ) 8-bit microprocessor
The 8085 has an 8-bit data bus and ALU (with a 16-bit address bus), so it is an 8-bit microprocessor.

-
In a little-endian system, a multi-byte value is stored with:
सही उत्तर: ख) its least significant byte at the lowest memory address
Little-endian (e.g. Intel x86) stores the least significant byte first, at the lowest address.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A pipeline hazard caused by branch or jump instructions is called a:
सही उत्तर: ख) control hazard
Branches change the flow of instructions, so the pipeline may fetch the wrong instructions; this is a control hazard.
