Understanding units of data

• Match the unit with its definition:

  Bit ↔️ Binary digit: 0 or 1

  Byte ↔️ 8 bits
• A kilobyte (KB) is equivalent to 1024 bytes.
• A kilobyte (KB) is used to measure the size of small files such as spreadsheets.
• How many bytes are there in a gigabyte (GB)?

  1,000,000,000
• 1 gigabyte is equal to 1,000,000,000 bytes in all contexts

  False
• A byte is composed of 8 bits and can represent 256 different values


  True
• A megabyte is exactly 1,000,000 bytes

  False
• A byte can represent 256 different values because it is composed of 8 bits


  True
• A megabyte is larger than a kilobyte


  True
• A petabyte (PB) is larger than a terabyte (TB)


  True
• A bit is a binary digit that can be either 0 or 1.
• How many possible combinations of 0s and 1s can a byte store?

  256
• How many bytes are there in a kilobyte (KB)?

  1024
• A megabyte (MB) is commonly used to measure the size of audio files and small video clips.


  True
• A gigabyte (GB) is a larger unit of data storage than a megabyte
• A bit is the most fundamental unit of data and can be either 0 or 1.
• A kilobyte (KB) is equal to 1,000 bytes or 1,024 bytes.
• A bit is a binary digit that can be either 0 or 1.
• A kilobyte is equal to 1,000 bytes or 1,024 bytes in some contexts.
• A terabyte (TB) is equivalent to 1,000 gigabytes or 1,000,000 megabytes.
• Petabytes are used to measure the storage capacity of massive data centers and cloud storage systems.
