📊 Computer Architecture
Q. The processor keeps track of the results of its operations using flags called
  • (A) conditional code flags
  • (B) test output flags
  • (C) type flags
  • (D) none of the mentioned
💬 Discuss
✅ Correct Answer: (A) conditional code flags

Explanation: these flags are used to indicate if there is an overflow or carry or zero result occurrence.

📊 Computer Architecture
Q. The register used to store the flags is called as
  • (A) flag register
  • (B) status register
  • (C) test register
  • (D) log register
💬 Discuss
✅ Correct Answer: (B) status register

Explanation: the status register stores the condition codes of the system.

📊 Computer Architecture
Q. In some pipelined systems, a different instruction is used to add to numbers which can affect the flags upon
  • (A) and gate
  • (B) nand gate
  • (C) nor gate
  • (D) xor gate
💬 Discuss
✅ Correct Answer: (D) xor gate

Explanation: none.

📊 Computer Architecture
Q. The most efficient method followed by computers to multiply two unsigned numbers is
  • (A) booth algorithm
  • (B) bit pair recording of multipliers
  • (C) restoring algorithm
  • (D) non restoring algorithm
💬 Discuss
✅ Correct Answer: (B) bit pair recording of multipliers

Explanation: none.

📊 Computer Architecture
Q. For the addition of large integers, most of the systems make use of
  • (A) fast adders
  • (B) full adders
  • (C) carry look-ahead adders
  • (D) none of the mentioned
💬 Discuss
✅ Correct Answer: (C) carry look-ahead adders

Explanation: in this method, the carries for each step are generated first.

📊 Computer Architecture
Q. In a normal n-bit adder, to find out if an overflow as occurred we make use of
  • (A) counter
  • (B) flip flop
  • (C) shift register
  • (D) push down stack
💬 Discuss
✅ Correct Answer: (C) shift register

Explanation: the shift registers are used to store the multiplied answer.

📊 Computer Architecture
Q. The smallest entity of memory is called
  • (A) cell
  • (B) block
  • (C) instance
  • (D) unit
💬 Discuss
✅ Correct Answer: (A) cell

Explanation: each data is made up of a number of units.

📊 Computer Architecture
Q. The collection of the above mentioned entities where data is stored is called
  • (A) block
  • (B) set
  • (C) word
  • (D) byte
💬 Discuss
✅ Correct Answer: (C) word

Explanation: each readable part of the data is called blocks.

📊 Computer Architecture
Q. If a system is 64 bit machine, then the length of each word will be
  • (A) 4 bytes
  • (B) 8 bytes
  • (C) 16 bytes
  • (D) 12 bytes
💬 Discuss
✅ Correct Answer: (B) 8 bytes

Explanation: a 64 bit system means, that at a time 64 bit instruction can be executed.

📊 Computer Architecture
Q. The type of memory assignment used in Intel processors is
  • (A) little endian
  • (B) big endian
  • (C) medium endian
  • (D) none of the mentioned
💬 Discuss
✅ Correct Answer: (A) little endian

Explanation: the method of address allocation to data to be stored is called as memory assignment.
