About these units
Floppy Disk (5.25", DD) (floppy (5.25" DD))
The 5.25-inch DD floppy stored roughly 360 KB (IBM PC) or 1.2 MB (Apple II and others) depending on format. These flexible disks dominated early personal computing in the 1980s. They were physically fragile but offered an affordable way to distribute software, operating systems, and games. The vast majority of early PC software—from Lotus 1-2-3 to original DOS versions—shipped on 5.25" disks. Their shape and texture became symbols of the early PC revolution, despite their low reliability, susceptibility to dust, and limited capacity.
Nibble (nibble)
A nibble consists of 4 bits, exactly half of a byte. It is the smallest unit that can represent a single hexadecimal digit (0–F), which makes it essential in low-level data representation. Nibble operations arise in microcontroller design, bitwise arithmetic, encryption algorithms, and early computing architectures that manipulated data in 4-bit chunks. Although modern systems process much larger word sizes, nibbles remain conceptually important: digital logic circuits still group bits in fours for hexadecimal notation, instruction encoding, and debugging tasks. In many ways, the nibble serves as the bridge between binary and human-readable representations of digital information.
