1, True-Fаlse аnd multiple-chоice questiоns. Fоr multiple-choice questions, there mаy be more than one correct answer. Please write the answer for each subquestion in the following blank. (1 point each). (1) The Arithmetic Logic Unit (ALU), does the major calculations in the computer, including And, Or, Nor, Addition, Subtraction, SLT, and BEQ instructions.(2) In single-cycle datapath and control, each instruction is executed in one clock cycle.(3) In pipelining, multiple instructions in the same stage are allowed to be executed in one clock cycle.(4) An optimal memory hierarchy uses larger and slower memory technologies close to the processor.(5) Virtual memory completes the interchange of information between the cache and main memory. (6) It is possible that the translation from virtual address to physical address exists in the Translation Lookaside Buffer (TLB) but does not exist in the page table. (7) Stack smashing is a technique where a return address is overwritten by writing outside of the intended data structure.(8) A Shadow stack is a second, separate stack that shadows the program call stack. Its disadvantage is that it is infeasible to test all variations of randomized software. (9) A half adder takes two inputs, a and b, and generates two outputs, the carry and the sum. For the carry output and sum output, identify which of the following logic equations are correct: A. carry = a OR bB. sum = the addition of a and bC. carry = a AND bD. sum = a XOR b (10) There are 4 elements holding data in a single datapath. They are the Program Counter, Instruction memory, Register file, and Data memory. Choose which of these elements are used for all instructions:A. Program CounterB. Instruction memory C. Register filesD. Data memory (11) Memory hierarchy takes advantage of the principle of locality. Which of the following are forms of locality?A. Only temporal localityB. Only spatial localityC. Both temporal locality and spatial localityD. None of the above(12) Data hazards happen when the following instructions are being executed. Identify possible ways to address the data hazards: lw $s0, 8($s1)add $s3, $s0, $s4A. Execute without Forwarding and StallingB. Forwarding C. StallingD. None of the above (13) Control hazards happen when the flow of instruction addresses is not what the pipeline expected. What are possible solutions to help mitigate control hazards (branch hazards)? A. Assuming branch not takenB. Performing branching in the ID stageC. branch predictionD. None of the above(14) Identify the goals of computer security:A. ConfidentialityB. IntegrityC. AuthenticityD. Availability(15) Identify the strategies to defend against stack smashing attacks: A. Address space layout randomizationB. Shadow stackC. Binary code randomizationD. None of the above
