How many megabytes are in one gigabyte?

• A. 512 megabytes
• B. 1,024 megabytes
• C. 2,048 megabytes
• D. 3,072 megabytes

Answer: (B)

One gigabyte (GB) is equivalent to 1,024 megabytes (MB). This relationship is based on the binary system that computers use, where data is measured in powers of two. Since one gigabyte represents 2^30 bytes and one megabyte represents 2^20 bytes, the conversion can be calculated as follows: 1 gigabyte = 2^30 bytes 1 megabyte = 2^20 bytes To find the number of megabytes in one gigabyte, you can calculate: 1 GB = (2^30 bytes) / (2^20 bytes) = 2^(30-20) = 2^10 = 1,024 MB This definition of measurement is standard in computing and is consistent across various storage and memory specifications. Understanding this conversion is essential for IT professionals when discussing storage capacities and data transfer sizes.

1 megabyte = 2^20 bytes

To find the number of megabytes in one gigabyte, you can calculate:

1 GB = (2^30 bytes) / (2^20 bytes) = 2^(30-20) = 2^10 = 1,024 MB
