About these units

Byte (B)

A byte consists of 8 bits, forming the standard grouping used in computing for representing characters, numbers, and machine instructions. This 8-bit size became dominant due to hardware design choices in early microprocessors, especially the IBM System/360 architecture. Bytes allow computers to represent values from 0 to 255, enabling ASCII encoding, color values, file metadata, and vast amounts of structured data. The byte is the basis for nearly all storage units—kilobytes, megabytes, gigabytes—and remains the fundamental digital "counting unit" for memory, disk space, and network transfers.

Kilobyte (kB)

A kilobyte traditionally represents 1,024 bytes (2¹⁰), reflecting binary-based memory design. Historically, operating systems, RAM modules, and floppy disks all used the binary kilobyte because memory addressing naturally aligned with powers of two. Kilobytes were once considered large: early computer programs and operating systems were measured in just a few kB. The first text-based adventure games fit entirely within 32 kB. Although kilobytes seem tiny today, they remain important for low-level embedded systems, boot loaders, configuration memory, and microcontrollers. The kilobyte is a reminder of computing's early constraints and the precision of binary address spaces.
