Which is the smallest of these data storage capacities?

The correct answer is 2KB
Important PointsIn digital storage, the smallest unit of measurement is a byte. A byte is a unit of information that can represent a single character or a small amount of data. It is comprised of 8 bits.

Given the options:

2 KB (kilobytes) - 1 kilobyte is equal to 1024 bytes. Therefore, 2 KB is equal to 2 * 1024 = 2048 bytes.

2049 Bytes - This option is stated as 2049 bytes, which is greater than 2048 bytes.

0.5 MB (megabytes) - 1 megabyte is equal to 1024 kilobytes, which is equal to 1024 * 1024 = 1,048,576 bytes.

Therefore, 0.5 MB is equal to 0.5 * 1024 * 1024 = 524,288 bytes.

3 GB (gigabytes) - 1 gigabyte is equal to 1024 megabytes,

which is equal to 1024 * 1024 * 1024 = 1,073,741,824 bytes. Therefore, 3 GB is equal to 3 * 1024 * 1024 * 1024 = 3,221,225,472 bytes.

Comparing the options, we find that 2048bytes means 2KB  is the smallest storage capacity mentioned.
