Which term refers to the collection of data sizes including Bit, Byte, Kilobyte (KB), Megabyte (MB), Gigabyte (GB), Terabyte (TB), and Petabyte (PB)?

• A. Bit size category
• B. Storage unit
• C. Memory type
• D. Data rate

Answer: (B)

These terms are data size measurements used to quantify how much data is stored or needed to store something. A Bit is the smallest unit, and a Byte is eight bits. Kilobyte, Megabyte, Gigabyte, Terabyte, and Petabyte are progressively larger units that describe data quantities at increasing scales. Collectively, they’re referred to as storage units (data size units) because they measure capacity or amount of data, not the speed of data transfer. They aren’t about rate, which would be data rate (bits per second), and they aren’t about the type of memory (like RAM or ROM). So the best term for this collection is storage unit.
