Final answer:
A computer with a resolution of 1280 × 1024 is using the SXGA standard, which stands for Super Extended Graphics Array.
Step-by-step explanation:
A computer set to a resolution of 1280 × 1024 is using the SXGA (Super Extended Graphics Array) standard. This resolution provides a 5:4 aspect ratio, which was commonly used in computer monitors before the widespread adoption of the 16:9 widescreen aspect ratios. The SXGA standard falls between XGA (Extended Graphics Array) and UXGA (Ultra Extended Graphics Array) in terms of resolution. WXGA (Wide Extended Graphics Array), on the other hand, generally refers to resolutions with a widescreen aspect ratio.
