How many kilobytes are in a megabyte according to common standards?

• A. 10
• B. 100
• C. 1024
• D. 1048576

Answer: (C)

In computing, sizes are typically based on powers of two. A kilobyte is 2^10 bytes, which is 1024 bytes, and a megabyte is 2^20 bytes, which equals 1024 kilobytes. So there are 1024 kilobytes in a megabyte. Note that some contexts use decimal definitions (1 KB = 1000 bytes, 1 MB = 1,000,000 bytes), which would put about 1000 KB per MB, but the binary standard is what this question follows.
