Explanation / Answer

1.One reason portable devices such as tablets and smart phones start up quickly compared to desktop computers is portable devices use flash memory for

secondary storage rather than a spinning mechanical hard drive.

True -- Flash memory takes less power compared to hard drives so smart phones strats up quickly

2. The CPU is located on RAM.

False -- Both RAM and CPU laid on Mother board

3. The access time for solid state memory (RAM, cache, etc.) is faster than the access time for the typical mechanical hard drive.
  
True -- access time of RAM is more than Hard drive because it is a temporary memory. It wont store data for long time.

4. The perceived performance of a computer (start-up time, how fast applications load and run, etc.) is determined exclusively by the speed of the CPU.

True -- According to processing speed only we can determine performance of computer, CPU allocates time to process the request.

5. The perceived performance (when doing everyday tasks) of a smart phone with a dual core processor will be twice that of a smart phone with a single core

processor and smart phone with a quad core processor will seem four times as fast as a smart phone with a single core processor.

False -- Quad core is not faster than single core but quad core handles with multiple apps.
for example to do a task single core takes full power where as quad core takes one fourth power to complete the task

6. Siri and Cortana are "intellegent" personal assistants from Apple and Microsoft respectively. What are programs such as these capable of?
A. primitive speech recognition, primitive natural language understanding
B. primitive speech recognition, sophisticated natural language understanding
C. sophisticated speech recognition, primitive natural language understanding
D. sophisticated speech recognition, sophisticated natural language understanding

Option A is right answer. these apps recognises the voice and performs tha task what user requests.

7. There is a difference between data and information. Which of the following is an example of information?
A. amount of money saved by having a roommate willing to split housing expenses
B. amount of money it cost to rent a certain apartment
C. amount of deposit on a certain apartment
D. interest rate on a credit card

Data is raw material where as Information is Useful thing.Make use of data to create information so we can say savings amount can be used as room expenses in a useful way

A is right answer.

8. Why do computers and other electronic devices get warm and risk overheating if not ventilated properly?
A. friction from mechanical hard drive
B. friction from electrons moving through circuits
C.thermal heating is used to raise temperatures to optimum level
D. radiant heating is used to raise temperatures to optimum level

B is right answer. according to first law of thermo dynamics energy can't be created nor destroyed, It can change from one form to another. Friction from moving

electrons will generate heat due lo low ventilation it heats up the electronic devices.

9. Where might you find a GPU on a computer? Check all that apply.
A.Separate discrete video card
B. mother board
C. CPU die

GPU stands for graphics processing unit. In computers GPU's laid on video card or embedded with mother board,in some computers it present on CPU.
So A,B,C options are right answers

10. If you are watching high definition video from an IPTV service such as Netflix, can you expect any difference in the quality of the video depending on if you

connect via Wi-Fi or Ethernet?
A. no difference
B. quality is likely to be better with Wi-Fi
C. quality is likely to be better with Ethernet

B -- quality is likely to be better with Wi-Fi
