About Byte (B)
The standard unit of digital information storage per IEC 80000-13:2008 (Quantities and units — Information science and technology). A byte is 8 bits — the smallest addressable unit on most modern computer architectures (x86, ARM, RISC-V, POWER) and the natural unit for storing a single ASCII character (US-ASCII 1968 standard, codes 0-127) or a single byte of UTF-8 (variable-length 1-4 byte Unicode encoding per RFC 3629). The 8-bit byte became the de facto standard with IBM System/360 (1964) and was formalized by ISO/IEC 2382-1 + the C99 + C++03 language standards. Historical systems used different byte widths: 6-bit (CDC 3000, Univac 1100), 7-bit (DEC PDP-10), 9-bit (DEC PDP-12, Honeywell 6000). Reference values: 1 byte stores 1 ASCII character, 2-4 bytes for Unicode/UTF-8/UTF-16/UTF-32, 8 bytes for a 64-bit integer or double-precision float (IEEE 754).
About Kilobyte (KB)
A unit of digital storage equal to 1,024 bytes (= 2¹⁰ bytes) in the binary (computing) convention used in most operating systems and software per JEDEC + Microsoft Windows conventions. The IEC 80000-13:2008 standard distinguishes the binary 'kibibyte' (KiB = 1,024 bytes) from the decimal 'kilobyte' (KB = 1,000 bytes per SI convention used by hard drive manufacturers WD/Seagate/Toshiba + most marketing material) — but this distinction is rarely observed in everyday usage. Reference values: a typical 80-column × 25-row terminal screen ~2 KB; a small text file or short email ~5-20 KB; a typical JSON API response payload 1-50 KB; the original Apple Macintosh 1984 had 128 KB total RAM; the IBM PC 5150 1981 shipped with 16-64 KB RAM. Today's NVMe SSDs read/write at GB/s rates, making the kilobyte a unit better suited for measuring small structured-data payloads + browser cookies + Lua scripts than file sizes.

Understanding Bytes
The Byte (symbol: B) is a unit of data storage. The standard unit of digital information storage per IEC 80000-13:2008 (Quantities and units — Information science and technology). A byte is 8 bits — the smallest addressable unit on most modern computer architectures (x86, ARM, RISC-V, POWER) and the natural unit for storing a single ASCII character (US-ASCII 1968 standard, codes 0-127) or a single byte of UTF-8 (variable-length 1-4 byte Unicode encoding per RFC 3629).

Understanding Kilobytes
The Kilobyte (symbol: KB) is a unit of data storage. A unit of digital storage equal to 1,024 bytes (= 2¹⁰ bytes) in the binary (computing) convention used in most operating systems and software per JEDEC + Microsoft Windows conventions. The IEC 80000-13:2008 standard distinguishes the binary 'kibibyte' (KiB = 1,024 bytes) from the decimal 'kilobyte' (KB = 1,000 bytes per SI convention used by hard drive manufacturers WD/Seagate/Toshiba + most marketing material) — but this distinction is rarely observed in everyday usage.
