You are comparing file sizes and need to identify which common storage unit represents approximately one million bytes. Which unit should you choose?
Megabyte
Gigabyte
Kilobyte
Terabyte
One megabyte (MB) represents exactly 1,000,000 bytes when decimal (base-10) prefixes are used, which is the convention CompTIA follows for storage measurements. By contrast, a kilobyte (KB) represents 1,000 bytes, a gigabyte (GB) represents 1,000,000,000 bytes, and a terabyte (TB) represents 1,000,000,000,000 bytes. Knowing these relationships helps you estimate file sizes and storage capacities accurately.
