INSY 2303 UTA Scott Final Exam Study Guide with Complete Solutions Digital vs. Analog - Correct Answer digital reads a series of ones and zeros, while analog reads a continuous flow of data.Lossy - Correct Answer Describes a method of compression in which data is lost in a way that cannot be recovered from the compressed data.Lossless Compression - Correct Answer a data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data.pixel interpolation - Correct Answer A process that is used by graphics software to average the color of adjacent pixels in an image, usually when the image is enlarged.Data vs. Information - Correct Answer Data = raw facts and figures. Information = meaningful interpretation of data.Bitmap vs. Vector Graphics - Correct Answer Bitmap Graphics: an image, such as a digital photo, that is stored as a grid work of colored dots.Vector Graphics: an image generated from descriptions that specify the position, length, and direction in which lines and shapes are drawn 3D graphics - Correct Answer A digital graphics format that displays a three-dimensional image in a two- dimensional space.Vectors - Correct Answer Lines and curves that form simple shapes rendering - Correct Answer In graphics software, the process of creating a 3D solid image by covering a wireframe drawing and applying computer-generated highlights and shadows 1 / 2
Ray tracing - Correct Answer The technique for adding light and shadows to a 3-D image Application - Correct Answer Computer programs that help users perform a specific task such as word processing.
