Homework Answers
The CPU and I/O subsystems function separately and are not dependent on each other to perform their tasks. I/O devices have their own controllers and do not need to utilize CPU cycles to execute. Not allowing the CPU to do other tasks during this time would cause the CPU to be idle, wasting clock cycles which could otherwise have been used to perform some computations.

Question 35 1 pts follows closely behind the CPU and memory in determining the overall effectiveness of a computer system. Virtual memory The fetch/decode/execute cycle Disk I/O None of these is correct. Question 36 5 pts Assume you have two upgrade options at the same cost. Option 1: upgrade to a CPU that's 50% faster or option 2: upgrade the 1.O system to make it 100% faster. Assume processes spend 80% of their time running in the CPU and 20%...

Question 4 [Points 4] Consider a system running 2 (two)CPU-bound tasks (C1-C2) and 1(one) I/O-bound tasks(I1). I/O bound task issues an I/O operation once every 1millisecond ofCPU. Each I/O operation takes 10milliseconds. Assume that there is only one I/O device (so multiple I/O requests may have to queue). Assume that the context switch takes 1 millisecond. Assume that each CPU-bound requires 20 milliseconds of CPU to complete and each I/O-bound task requires 2millisecondof CPU time. Show through a Ganttt chart...

Question 10 2 pts Why do trees need water to reach their leaves? Water is important for photosynthesis because it replenishes electrons to the electron transport chain in the light reactions. Water is important for cellular respiration because it accepts the electron in the electron transport chain. Water is important because it is a major product of photosynthesis. Water is important because it is consumed during the Calvin Cycle. 2 pts Question 11

19:49 Exit Question 8 5 pts A subsistence farmer wishes to diversify her crops. She goes to the market to buy seeds. There are three crops she can choose from: Apples, Bananas, and Coconuts. She does not have enough money to buy seeds for all three crops, so she must choose only two. She consults her friends and learns the yield of apples, bananas, and coconuts from the previous 4 years, shown in the table below. If she is risk...

D Question 7 1 pts Why does the absorption spectrum of aqueous [TI(OH2)]* exhibit a broad band with a shoulder? O An Intervalence Charge Transfer absorption overlaps with the d-d absorption. O [TI(OH2)]3+ contains ad Ti-ion and upon light absorption, there is degeneracy in the excited state leading to a Jahn-Teller distortion. O [TI(OH)]3+ contains ad Ti-ion and therefore there are two absorptions. O [TI(OH2)]** is partly reduced to [TI(OH)]2+ in aqueous solution and two absorptions which are...

Question 1 5 pts What is WACC? Why is it important? O The firm's required return. It is used as the discount rate in NPV and it is used to compare to IRR. O It is the required return on debt. O It is the firm's required return. If IRR is less than WACC, you should accept the project. O It is the required return on equity. Question 2 5 pts What are some of the issues with the payback...

Question 1 1 pts Why is it important for DNA to have complementary base pairing? O Complementary base pairing allows base pairs to be packed in the most energetically favorable arrangement inside of the double helix structure. O Complementary base pairing will pair a purine with a purine, which are a similar width, thus they are able to hold the sugar-phosphate backbone an equal distance apart along the DNA molecule o Complementary base pairing is only important for maintaining the...
