📊 Computer Architecture
Q. When using the Big Endian assignment to store a number, the sign bit of the number is stored in
  • (A) the higher order byte of the word
  • (B) the lower order byte of the word
  • (C) can’t say
  • (D) none of the mentioned
💬 Discuss
✅ Correct Answer: (A) the higher order byte of the word

Explanation: none.

📊 Computer Architecture
Q. To get the physical address from the logical address generated by CPU we use
  • (A) mar
  • (B) mmu
  • (C) overlays
  • (D) tlb
💬 Discuss
✅ Correct Answer: (B) mmu

Explanation: memory management unit, is used to add the offset to the logical address generated by the cpu to get the physical address.

📊 Computer Architecture
Q. method is used to map logical addresses of variable length onto physical memory.
  • (A) paging
  • (B) overlays
  • (C) segmentation
  • (D) paging with segmentation
💬 Discuss
✅ Correct Answer: (C) segmentation

Explanation: segmentation is a process in which memory is divided into groups of variable length called segments.

📊 Computer Architecture
Q. During the transfer of data between the processor and memory we use
  • (A) cache
  • (B) tlb
  • (C) buffers
  • (D) registers
💬 Discuss
✅ Correct Answer: (D) registers

Explanation: none.

📊 Computer Architecture
Q. Physical memory is divided into sets of finite size called as
  • (A) frames
  • (B) pages
  • (C) blocks
  • (D) vectors
💬 Discuss
✅ Correct Answer: (A) frames

Explanation: none.

📊 Computer Architecture
Q. Add #%01011101,R1 , when this instruction is executed then
  • (A) the binary addition between the operands takes place
  • (B) the numerical value represented by the binary value is added to the value of r1
  • (C) the addition doesn’t take place, whereas this is similar to a mov instruction
  • (D) none of the mentioned
💬 Discuss
✅ Correct Answer: (A) the binary addition between the operands takes place

Explanation: this performs operations in binary mode directly.

📊 Computer Architecture
Q. If we want to perform memory or arithmetic operations on data in Hexa- decimal mode then we use symbol before the operand.
  • (A) ~
  • (B) !
  • (C) $
  • (D) *
💬 Discuss
✅ Correct Answer: (C) $

Explanation: none.

📊 Computer Architecture
Q. When generating physical addresses from a logical address the offset is stored in
  • (A) translation look-aside buffer
  • (B) relocation register
  • (C) page table
  • (D) shift register
💬 Discuss
✅ Correct Answer: (B) relocation register

Explanation: in the mmu the relocation register stores the offset address.

📊 Computer Architecture
Q. The technique used to store programs larger than the memory is
  • (A) overlays
  • (B) extension registers
  • (C) buffers
  • (D) both extension registers and buffers
💬 Discuss
✅ Correct Answer: (A) overlays

Explanation: in this, only a part of the program getting executed is stored on the memory and later swapped in for the other part.

📊 Computer Architecture
Q. The unit which acts as an intermediate agent between memory and backing store to reduce process time is
  • (A) tlb’s
  • (B) registers
  • (C) page tables
  • (D) cache
💬 Discuss
✅ Correct Answer: (D) cache

Explanation: the cache’s help in data transfers by storing most recently used memory pages.
