White box (computer hardware)
In computer hardware, a white box is a personal computer or server without a well-known brand name. For instance, the term is applied to systems assembled by small system integrators and to homebuilt computer systems assembled by end users from parts purchased separately at retail. In this latter sense, building a white box system is part of the DIY movement. The term is also applied to high volume production of unbranded PCs that began in the mid-1980s with 8MHz “Turbo XT” systems selling for just under $1000.
Data degradation, also known as data decay or data rot, is a colloquial computing phrase for the gradual decay of storage media.
