Why each option
In computing, 2KB (kilobytes) represents 2048 bytes, as one kilobyte is precisely 1024 bytes.
1024 bytes is equal to 1KB, not 2KB.
In computer science, a kilobyte (KB) is traditionally defined as 1024 bytes, not 1000 bytes, due to the binary nature of computing (2^10 = 1024). Therefore, 2KB would be calculated as 2 multiplied by 1024 bytes, which equals 2048 bytes.
20000 bytes would be 20KB if using the decimal system (20 * 1000), but not the correct binary definition for 2KB.
1048576 bytes is equal to 1MB (megabyte), which is 1024 * 1024 bytes.
