Which of the following statement is valid?

  • A.1MB = 2048 bytes
  • B.1KB = 1024 bytes
  • C.1KB = 1000 bytes

  • D.1MB = 1024 bytes

Answer: B

Correct answer: 1KB = 1024 bytes

The binary prefixes step by 1024, so a kilobyte is 1024 bytes and a megabyte is 1024 kilobytes, or 1,048,576 bytes. The options giving 1000 bytes to the kilobyte and 1024 bytes to the megabyte both break that sequence.
