-
Which level of cache is the smallest and fastest, located inside each CPU core?
सही उत्तर: क) L1 cache
L1 cache is closest to the core, smallest in size and fastest; L2 and L3 are larger and slower.

DDR SDRAM achieves higher bandwidth than ordinary SDRAM mainly because it:
सही उत्तर: घ) transfers data twice per clock cycle, on the rising and the falling edge
Double Data Rate RAM transfers data twice per clock cycle, doubling the data rate at the same clock speed.

EEPROM differs from EPROM in that EEPROM can be erased:
सही उत्तर: ग) electrically, without removing it from the circuit
EEPROM (Electrically Erasable PROM) is erased and rewritten electrically, while EPROM needs UV light.

-
A DRAM cell stores one bit as:
सही उत्तर: ख) electric charge on a small capacitor
A DRAM cell uses one transistor and one capacitor; the charge leaks, so it must be refreshed.

A math co-processor such as the Intel 8087 was designed mainly to speed up:
सही उत्तर: ख) floating-point arithmetic
The 8087 floating-point unit performed floating-point calculations much faster than the 8086 alone.

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.
