The Intel 8085 microprocessor has a 16-bit address bus. The maximum memory it can address directly is:
सही उत्तर: क) 64 KB
16 address lines give 2^16 = 65,536 locations = 64 KB.

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.

-
An instruction such as ADD A, B, C, which names two source operands and a separate destination, uses which instruction format?
सही उत्तर: घ) Three-address
Three address fields are given: two sources (B and C) and one destination (A).

Compared with a microprogrammed control unit, a hardwired control unit is generally:
सही उत्तर: ख) faster but harder to modify
Hardwired control uses fixed logic circuits, giving high speed but requiring redesign for any change.

-
The term 'von Neumann bottleneck' refers to:
सही उत्तर: क) the limited data transfer rate between the CPU and memory over a shared path for instructions and data
Because instructions and data travel over the same path between CPU and memory, the processor often waits for memory.

Branch prediction in a pipelined processor is used to:
सही उत्तर: ख) guess the outcome of a branch so the pipeline can keep fetching instructions
Predicting branches avoids stalling the pipeline while the actual branch outcome is being computed.

-
Simultaneous multithreading, marketed by Intel as Hyper-Threading, allows:
सही उत्तर: ग) one physical core to run two threads at once, appearing as two logical processors
SMT duplicates the architectural state so one core can issue instructions from two threads, appearing to the OS as two logical CPUs.

-
In the classic five-stage RISC pipeline (IF, ID, EX, MEM, WB), which stage comes immediately after instruction decode?
सही उत्तर: घ) Execute (EX)
The order is fetch, decode, execute, memory access and write back.

-
Most RISC processors follow a load/store architecture, which means that:
सही उत्तर: घ) only load and store instructions access memory, while arithmetic works on registers
In a load/store design, operands are first loaded into registers, processed there, and results are stored back by separate instructions.

-
Which logic family is built using bipolar junction transistors?
सही उत्तर: घ) TTL
TTL uses bipolar junction transistors, whereas CMOS, NMOS and PMOS are based on MOSFETs.
