Petabytes are just a unit of measurement that are prevalent in anything computer. Though, on a scale of one to ten, I doubt it's really that interesting due to its obscurity. A

Questions and Answers

1.

Describe a petabyte with the International System of Units
- A.
  
  10^5
- B.
  
  10^15
- C.
  
  10^12
- D.
  
  10^25
Correct Answer
B. 10^15

Explanation
A petabyte is a unit of digital information storage capacity that is equal to 10^15 bytes. It is commonly used to measure large amounts of data, such as in big data analytics or cloud storage. The prefix "peta" in the International System of Units represents a factor of 10^15, which is why the correct answer is 10^15.

How many terabytes is one petabyte?
- A.
  
  200
- B.
  
  500
- C.
  
  1000
- D.
  
  1500
Correct Answer
C. 1000

Explanation
One petabyte is equal to 1000 terabytes. The prefix "peta" represents a factor of 10^15, while the prefix "tera" represents a factor of 10^12. Therefore, when converting from petabytes to terabytes, we need to multiply the value by 10^3, resulting in 1000 terabytes.

How many petabytes is equal to one exabyte?
- A.
  
  100
- B.
  
  200
- C.
  
  500
- D.
  
  1000
Correct Answer
D. 1000

Explanation
One exabyte is equal to 1000 petabytes. This is because the metric system uses powers of 10 to represent larger units of data storage. Each unit is 1000 times larger than the previous one. Therefore, one exabyte is 1000 times larger than one petabyte.

One petabyte storage, full of music of 1 mb per minute, will take how long to finish?
- A.
  
  3800 years
- B.
  
  4300 years
- C.
  
  1800 years
- D.
  
  2000 years
Correct Answer
D. 2000 years

Explanation
Assuming that the question is asking how long it would take to finish listening to all the music stored in one petabyte (which is a unit of digital storage), we can calculate the time by dividing the total storage capacity (1 petabyte) by the size of each song (1 megabyte) and then converting it to years. Since there are 1,048,576 megabytes in a petabyte, dividing it by 1 gives us 1,048,576 minutes. Converting this to years, we get approximately 2000 years.
