480K

480K is a designation that can refer to several different things, most commonly associated with storage capacity. In the context of early personal computers and floppy disks, 480K typically refers to a storage capacity of approximately 480 kilobytes. This was a common size for high-density 5.25-inch floppy disks used in systems like the IBM PC and its compatibles during the 1980s. The actual usable space could vary slightly due to formatting and file system overhead.

The term "480K" can also appear in other technical contexts, though less frequently. For example, it might be used in reference to certain types of memory or data transfer rates, though these applications are not as widespread as its association with floppy disk storage. When encountered, understanding the specific context is crucial to accurately interpreting what "480K" signifies. The persistence of this designation in retro computing discussions highlights its historical significance in the evolution of digital storage.
