In a human DNA, the parts that distinguish one person from another can be compressed to how many megabyte?
-
3
-
6
-
5
-
4
Correct Answer
A. 4Explanation
The parts of human DNA that distinguish one person from another can be compressed to approximately 4 megabytes. This suggests that the genetic information that makes each individual unique can be stored in a relatively small amount of digital data.Rate this question:

By 2020, allegedly how many megabyte of data will be created for every human per second?
-
1.0 MB
-
1.2 MB
-
1.7 MB
-
1.5 MB
Correct Answer
A. 1.7 MBExplanation
By 2020, it is estimated that 1.7 megabytes of data will be created for every human per second. This suggests that the amount of data being generated is increasing rapidly, highlighting the growing importance and reliance on digital information in our daily lives.Rate this question:

Which one is connected to a MB?
-
10^6
-
10^5
-
10^4
-
10^7
Correct Answer
A. 10^6Explanation
The correct answer is 10^6. In computer storage, a MB refers to a Megabyte, which is equal to 10^6 bytes. Therefore, 10^6 is the only option that is connected to a MB. The other options represent different quantities, such as 10^5 (100,000), 10^4 (10,000), and 10^7 (10,000,000), which are not equivalent to a Megabyte.Rate this question:

Describing MB as bytes, which one does that the best?
-
2^30 B
-
2^25 B
-
2^15 B
-
2^20 B
Correct Answer
A. 2^20 BExplanation
The correct answer is 2^20 B because it represents the quantity of bytes most accurately. 2^30 B is a gigabyte, which is significantly larger than a megabyte. 2^25 B is in between a megabyte and a gigabyte, so it does not accurately describe a megabyte. 2^15 B is significantly smaller than a megabyte. Therefore, 2^20 B is the closest approximation to a megabyte.Rate this question:

128 Kbit/s MP3 compressed music, in megabyte, equals to how many minutes?
-
4 minutes
-
3 minutes
-
2 minutes
-
1 minute
Correct Answer
A. 1 minuteExplanation
128 Kbit/s MP3 compressed music means that the music is compressed at a rate of 128 kilobits per second. To determine the size of the music file in megabytes, we need to convert kilobits to megabits and then to megabytes. Since there are 8 bits in a byte, 128 kilobits is equal to 16 kilobytes. Therefore, the music file is 16 kilobytes in size. Since there are 1024 kilobytes in a megabyte, the music file is approximately 0.0156 megabytes. Since the music is 0.0156 megabytes in size, it would take approximately 1 minute to play the music file.Rate this question:

How many megabytes make one gigabyte (base 10)?
-
Two thousand and twenty-four
-
Two thousand
-
One thousand and twenty-four
-
One thousand
Correct Answer
A. One thousandExplanation
One gigabyte is equal to one thousand megabytes in base 10. In the base 10 numbering system, each unit is multiplied by 10 to the power of the unit above it. Therefore, when converting from megabytes to gigabytes, we divide by 1000.Rate this question:

How megapixel will a picture (JPEG) be, in terms of MB?
-
3
-
4
-
5
-
6
Correct Answer
A. 4Explanation
A picture with 4 megapixels in JPEG format will be approximately 4 MB in size. This is because the size of a JPEG file depends on various factors such as the level of compression, color depth, and image content. Generally, a higher number of megapixels results in a larger file size as more data is captured and stored in the image. However, the specific size can vary depending on the compression algorithm used and the level of detail in the image.Rate this question:
