Arrange the storage media in order of relative storage size from smallest to largest. CD
thumb drive
DVD
hard disk
Flash memory
Blue-ray

CD (700 MB)

DVD (17.0 GB)

Blue-ray (50 GB)

Thumb drive (2 TB)

Hard Disk (20 TB)

Flash Memory (100 TB)

***WARNING*** Values shown are for maximums in 2020.

Explanation:

For this problem let's assume 2020 standards and that the question is asking about the storage size in terms of data storage and not physical size.  Let's define the maximums for each of the following items:

CD -->  Maximum size of 700 MB (Standard)

thumb drive --> Maximum size 2TB (Made by Kingston)

DVD (1 sided/ 1 layer) --> 4.7 GB (Retrieved from Quora user Daniel Dillon)

DVD (1 sided/ 2 layer) --> 8.5 GB (Retrieved from Quora user Daniel Dillon)

DVD (2 sided/ 1 layer) --> 9.4 GB (Retrieved from Quora user Daniel Dillon)

DVD (2 sided/ 2 layer) --> 17.0 GB (Retrieved from Quora user Daniel Dillon)

hard disk --> 20 TB (Made by Western Digital and Segate)

Flash memory --> 100 TB ( Made by NimbusData retrieved from techrader.com)

Blue-ray (single-layer) --> 25 GB ( Standard issued by Samsung )

Blue-ray (dual-layer) --> 50 GB ( Standard issued by Samsung)

Now that we have these maximums as defined in 2020, let's sort them from smallest to largest in terms of data storage size.

Note, 1 MB < 1GB < 1TB.

CD (700 MB)

DVD (17.0 GB)

Blue-ray (50 GB)

Thumb drive (2 TB)

Hard Disk (20 TB)

Flash Memory (100 TB)

Note, the order of maximum storage may be different than what your assignment seeks based on whatever year's data the assignment is looking for.  This assortment is for technology available in 2020.

Cheers.

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
