In 1995, the National Institute of Standards & Technology (NIST) developed a revised definition of binary numbers to clarify confusion. Unlike rounded values commonly used as references, NIST binary expresses the true binary value. For example, a “megabyte” is often referred to as one million bytes, but the true binary value is 1,048,576 bytes. This value is always stated in specifications for digital devices. NIST uses the term “mebibyte” to represent this real binary value.
FAQ
What is NIST Binary?
NIST Binary is a revised definition of binary numbers developed by the National Institute of Standards & Technology (NIST) in 1995. It differs from ordinary references, which are often rounded values, by expressing the true binary value. This is important when dealing with specifications for digital devices.
WHAT is NIST Binary?
NIST Binary is a way to accurately represent binary values, such as the size of digital files or storage capacity, without rounding or approximation. It ensures precision and consistency when specifying the binary values of various digital devices.
For example, the term “megabyte” is commonly used to refer to one million (10^6) bytes. However, the true binary value of a megabyte is 1,048,576 (2^20) bytes. NIST Binary uses the term “mebibyte” to represent the true binary value of a megabyte.
When you see specifications for digital devices that involve file sizes or storage capacities, NIST Binary ensures that the values are stated accurately and in their true binary form. This eliminates confusion and ensures consistency in the digital industry.
NIST Binary is particularly relevant when it comes to comparing the binary values of digital storage devices, such as hard drives and solid-state drives. It provides a standardized way to express the actual binary capacity of these devices, enabling consumers and professionals to make accurate comparisons and decisions based on their specific needs.
In summary, NIST Binary is a revised definition of binary numbers that ensures accuracy and precision when specifying the binary values of digital devices. It eliminates confusion caused by rounded values and provides a standardized way to express the true binary capacity of digital storage devices.
