Discussion
Which of the given options best describes the truthfulness of the following statements?
i) A compiler translates the entire source code line by line.
ii) Computer architecture refers to those attributes of a system visible to a programmer.
iii) The Reduced Instruction Set Architecture (RISC) computer organisation reduces the cycles per instruction at the cost of the number of instructions per program to increase the CPU performance.
iv) All the arithmetic and logical processing is performed by the Arithmetic Logic Unit under the supervision of a control unit.
Answer: B
Statement i is false and statements ii, iii and iv are true. A compiler translates the whole source program at once into machine code, and it is an interpreter that works line by line, so statement i is wrong. Computer architecture means the attributes of a system visible to the programmer. RISC cuts the cycles per instruction at the cost of more instructions per program, and the arithmetic and logical work is done by the ALU under the control unit. So i-False, ii-True, iii-True and iv-True is correct.
