Quick computer science questions. Answer ALL 1-10 for positive rate.

1. Fact An older edition of our text book stated, "The initial SPARC was a full 32-bit machine, running at 36 MHz." What was the approximate cycle time of the initial SPARC machine measured in nanoseconds? A: 0.25 B: 2.5 C: 25 D: 50 E: 100 2. Fact Our text book states, "A digital computer consists of an interconnected system of processors, memories and input/output devices." T or F? Digital computer system components are interconnected by one or more buses. 3. T or F? While a machine language program is being executed by a computer, the central processing unit's Program Counter register (PC) holds the address of the next instruction to be fetched for execution. 4. Which computer component decodes and controls the execution of a program's machine language instructions? A: ALU B: CU C: IR D: PC E: clock 5. Which computer component contains the machine language instruction while it is being executed? A: ALU B: CU C: IR D: PC E: clock 6. Which computer component is used to do arithmetic and logical computations? A: ALU B: CU C: IR D: PC E: clock 7. Which computer component synchronizes operations both inside and outside the central processing unit? A: ALU B: CU C: IR D: PC E: clock 8. Fact Pipelining is instruction-level parallelism; that is, T or F? pipelining is the parallel or concurrent execution during the execution of a single machine instruction. 9. T or F? The more stages in a CPU pipeline, the shorter CPU's latency. access to main memory locations. 10. Typically, access to secondary storage devices is A: slower than B: about the same as C: faster than E: none of these
