Concept explainers
Metric prefixes are also used for computers. A byte is the amount of computer memory needed to store one alphanumeric character. In reference to computers you may hear the following words: kilobytes, megabytes, and gigabytes. Use the following chart to convert the measurements in exercises 70–73.
1 gigabyte (GB) = one billion bytes = 1,000,000,000 bytes |
1 megabyte (MB) = one million bytes* = 1,000,000 bytes |
1 kilobyte (KB) = one thousand bytes† = 1,000 bytes |
* Sometimes in computer science 1 megabyte is considered to be 1,048,576 bytes. |
†Sometimes in computer science 1 kilobyte is considered to be 1024 bytes. |
