A kilobyte (kB) is a unit of digital information or data storage equal to 1,000 bytes.
The plural form is kilobytes.
While a kilobyte (kB) is standardized as 1,000 bytes (using the decimal, or base-10 system), the term has historically been used in computing to mean 1,024 bytes.
This is because computers operate on a binary (base-2) architecture, and 210 equals 1024.
To clear up this confusion, the term kibibyte (KiB) was officially created to refer specifically to 1,024 bytes.
However, you'll still see "kilobyte" used informally for both values, especially in older software and operating systems like Windows.
In the dawn of early personal computing, the kilobyte was a massive unit of memory.
For example, the popular Commodore 64 home computer, released in 1982, had its name derived from its 64 kilobytes of RAM.
This was considered a large and powerful amount of storage capacity at the time, and it had to hold the entire operating system, programs, and any user data simultaneously.
In today's digital world, a kilobyte is a minimal amount of data.
A single kilobyte can typically hold about half a page of plain, unformatted text.
For reference, a simple email with no images might be 2-3 kB, while a small website icon (a favicon) is often around 1-4 kB.
It's the foundational unit upon which larger file sizes are built.
