How many bytes are there in 1 kilobyte?

A.

1036 bytes

B.

1064 bytes

C.

1012 bytes

D.

1024 bytes

Correct option is D

Correct Answer: (D). 1024 bytes


In digital storage, 1 kilobyte (KB) is traditionally defined as 1024 bytes. This is based on the binary system, where each unit is a power of 2.
Although in some contexts, particularly in marketing, 1 kilobyte may be approximated as 1000 bytes (decimal system), the correct standard unit in most computing contexts is 1024 bytes.

Here’s a list of common data storage units, from bytes to terabytes:
  • 1 Byte (B) = 8 bits
  • 1 Kilobyte (KB) = 1024 Bytes

  • 1 Gigabyte (GB) = 1024 Megabytes (MB)
  • 1 Terabyte (TB) = 1024 Gigabytes (GB)
  • 1 Petabyte (PB) = 1024 Terabytes (TB)
  • 1 Exabyte (EB) = 1024 Petabytes (PB)
  • 1 Zettabyte (ZB) = 1024 Exabytes (EB)
  • 1 Yottabyte (YB) = 1024 Zettabytes (ZB)
