  1,024 KB
• A byte is composed of 8 bits
• A terabyte contains 1,024 gigabytes.


  True
• A bit can represent two states: 0 or 1
• A byte can represent 256 different values.


  True
• Order the following data units from smallest to largest:

  1️⃣ Bit

  2️⃣ Byte

  3️⃣ Kilobyte

  4️⃣ Megabyte

  5️⃣ Gigabyte

  6️⃣ Terabyte

  True
• What is a terabyte (TB) equal to in gigabytes (GB)?

  1,024 GB
• Terabytes are commonly used to measure the storage capacity of large hard drives
• What number do you multiply or divide by to convert between data units?

  1,024
• 5 MB is equal to 5,120 KB

• Arrange the following data units from smallest to largest:

  1️⃣ Bit

  2️⃣ Byte

  3️⃣ Kilobyte

  4️⃣ Megabyte

  5️⃣ Gigabyte

  6️⃣ Terabyte
• A bit can represent one of two states: 0 or 1
• A kilobyte is exactly 1,000 bytes.

  False
• Why is a kilobyte defined as 1,024 bytes instead of 1,000?

  Binary system
• A megabyte is primarily used for storing large video files.

  False
• Match the data unit with its size:

  Bit ↔️ Smallest unit, 0 or 1

  Byte ↔️ 8 bits

  Kilobyte ↔️ 1,024 bytes

  Megabyte ↔️ 1,024 kilobytes

  1,024 KB
• A file that is 5 MB in size contains 5,120 KB of data.


  True
• What is a gigabyte (GB) equal to in megabytes (MB)?

  1,024 MB
