Kilobyte意思

"Kilobyte" (KB) is a unit of measurement for digital information or data storage. It is defined as 1,024 bytes (or 2^10 bytes). In the context of computer memory or storage, a kilobyte is a relatively small amount, with modern devices often using megabytes (1,024^2 bytes), gigabytes (1,024^3 bytes), or even larger units.

For example, a typical plain text email might be a few kilobytes in size, while a high-resolution digital image can be several megabytes or more. As technology has advanced, the kilobyte has become a relatively insignificant unit for measuring the storage capacity of devices such as computers, smartphones, and external hard drives, which often have capacities measured in terabytes (1,024^4 bytes) or even petabytes (1,024^5 bytes).
