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.
About Megabyte (MB)
A unit of digital storage equal to 1,048,576 bytes (= 1,024² = 2²⁰ bytes) in the binary (computing) convention per JEDEC, or 1,000,000 bytes (= 10⁶) in the decimal (SI) convention per IEC 80000-13 + hard-drive manufacturer marketing. The IEC distinguishes 'mebibyte' (MiB = 1,048,576 bytes binary) from 'megabyte' (MB = 1,000,000 bytes decimal) but the distinction is rarely observed — Windows + macOS Finder + Linux ls -h all display sizes in the binary KB/MB/GB sense. Reference values: an MP3 audio file at 128 kbps ~1 MB/minute; a typical high-resolution JPEG photo 2-8 MB; a 1080p YouTube video at standard quality ~1-2 MB/minute; the original Linux 0.01 kernel source code (1991) ~71 KB; the original Windows 1.0 (1985) shipped on 4 × 5.25-inch floppies totaling ~1.4 MB; a Compact Disc Audio (1982) holds 700 MB. Web standards traditionally treat 1 MB as a 'large' page-weight target (Google PageSpeed warns at 5+ MB total page weight).

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.

Understanding Megabytes
The Megabyte (symbol: MB) is a unit of data storage. A unit of digital storage equal to 1,048,576 bytes (= 1,024² = 2²⁰ bytes) in the binary (computing) convention per JEDEC, or 1,000,000 bytes (= 10⁶) in the decimal (SI) convention per IEC 80000-13 + hard-drive manufacturer marketing. The IEC distinguishes 'mebibyte' (MiB = 1,048,576 bytes binary) from 'megabyte' (MB = 1,000,000 bytes decimal) but the distinction is rarely observed — Windows + macOS Finder + Linux ls -h all display sizes in the binary KB/MB/GB sense.
