Final answer:

Aliasing is a phenomenon that occurs when a signal or image is sampled or measured at a lower rate than its original frequency or resolution.

Step-by-step explanation:

Aliasing is a phenomenon that occurs when a signal or image is sampled or measured at a rate that is lower than its original frequency or resolution.

In the context of computers and technology, aliasing is commonly seen in digital images, audio signals, and computer graphics. It can cause distorted or jagged edges, moiré patterns, and loss of detail.

To eliminate aliasing, various techniques are used depending on the specific domain. In digital images, anti-aliasing filters and algorithms can be applied to smooth out edges and reduce artifacts. In audio signals, anti-aliasing filters are used during sampling, and oversampling techniques can be employed to increase the effective sampling rate. For computer graphics, techniques like anti-aliasing and super-sampling can be used to eliminate aliasing artifacts.
