INSY 2303 Final Exam Review Questions
& Answers 2024/2025
Convergence - ANSWERSA process which several technologies with distinct functionalities evolve to form
a single product
it created sophisticated mobile devices who owners demanded services like a desktop computer -
ANSWERSWhy was convergence important to the digital revolution
Cloud computing - ANSWERSA system in which all computer programs and data is stored on a central
server owned by a company (e.g. Google) and accessed virtually
- 4th phase of digital revolution
Digital data - ANSWERStext, numbers graphics sound and video that have been converted into discrete
digits (0s and 1s)
Analog data - ANSWERSData measured or represented on a continuously varying scale
Data compression - ANSWERSany technique that recodes the data in a file so that it contains fewer bits
Zipping - ANSWERSData compression is also known as
Lossless - ANSWERSway to compress data and reconstitute it into its ORIGINAL state
Lossy - ANSWERSThrows away some of the original data during the compression process
- not the same as the original
extracting or unzipping - ANSWERSProcess of reconstituting files is called
, Pixel interpolation - ANSWERSprocess that is used by graphics software to average the color of adjacent
pixels in an image
- usually the nan image is enlarged
Data - ANSWERSSymbols that represent people, events, things, and ideas
- can be a name, number, the colors of a photograph
Information - ANSWERSUsed by humans, its data presented in as a way people can understand
Bitmap - ANSWERSComposed of a grid of tiny rectangular cells each cell is a picture element called a
pixel. Each pixel is assigned a color stored as a binary number.
Vector graphic - ANSWERSConsists of a set of instructions for creating a picture. Vector graphics file
contains instructions that a computer uses to create shape, size, position and color for each object in an
image.
3D graphics - ANSWERSBased on vectors stored as a set of instructions describing the coordinates for
lines and shapes in a three-dimensional space
Vectors - ANSWERSthe vectors form a wireframe
Rendering - ANSWERSthe process of covering a wireframe with surface color and texture
surface dimensions btw vectors - ANSWERSrendering requires a computer to perform intensive
calculations to determine
ray tracing - ANSWERSThe technique for adding light and shadows to a 3D image
Ease of editing - ANSWERSAbility to edit vector or bit map. Vector easier to edit
