UTA INSY 2303 EXAM SCRIPT WITH
VERIFIED QUESTIONS AND ANSWERS
●● Lossy
Answer: Describes a method of compression in which data is lost in a
way that cannot be recovered from the compressed data.
●● Lossless Compression
Answer: a data compression algorithm that allows the original data to be
perfectly reconstructed from the compressed data.
●● pixel interpolation
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
Answer: Data = raw facts and figures. Information = meaningful
interpretation of data.
●● Bitmap vs. Vector Graphics
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
Answer: A digital graphics format that displays a three-dimensional
image in a two-dimensional space.
●● Vectors
Answer: Lines and curves that form simple shapes
●● rendering
Answer: In graphics software, the process of creating a 3D solid image
by covering a wireframe drawing and applying computer-generated
highlights and shadows
●● Ray tracing
Answer: The technique for adding light and shadows to a 3-D image
●● Application
Answer: Computer programs that help users perform a specific task such
as word processing. Also called application programs, applications, or
programs.
●● Operating System
, Answer: The software that controls the computer's use of its hardware
resources, such as memory and disk storage space. Also called an OS.
●● Magnetic Storage
Answer: A technology for recording data onto disks or tape by
magnetizing particles of an oxide-based surface coating.
●● Optical Storage
Answer: A technology that records data as light and dark spots on a CD,
DVD, or other optical media
●● Solid state storage
Answer: A technology that records data and stores it in a microscopic
grid of cells on a nonvolatile, erasable, low-power chip
●● Cloud Storage
Answer: A storage area that is located on a remote server, usually on the
Internet, rather than on a local storage device
●● ALU
Answer: (Arithmetic Logic Unit) The part of the CPU that performs
arithmetic and logical operations on the numbers stored in its registers
●● Control Unit
