Presario is a series of desktop computers and notebooks from Compaq. The Presario family of computers was launched for the consumer marketplace in September 1993. In the mid-1990s, Compaq began manufacturing PC monitors as part of the Presario brand. A series of all-in one units, containing both the PC and the monitor in the same case, were also released. Although HP acquired Compaq in 2002, the Presario name was used until the Compaq brand was discontinued in 2013, due to its marketability.

The Presario CDS 520 Computer only supports 66MHz Intel i486DX. The Presario CDS 520 features two on-board data caches for transferring information to and from the processor. These caches are known as the L1 and L2 caches. The Presario CDS 520 L1 cache is 64 kilobytes in size, while its L2 cache is rated at either one or two megabytes.
