UTA INSY 2303 Final Exam Review
Convergence Correct answers The expansion of cloud computing, a process
by whichtechnologies with distinct functionalities evolve to form a single
several
product. Your
computer plays movies. Your cell phone has a camera. Your clock has
a radio.
Cloud computing Correct answers A process that provided access to
information,
applications, communications, and storage over the
Internet.
Digital data Correct answers Text, numbers, graphics, or sound represented
by discrete
digits, such as 1s and
0s.
Analog data Correct answers Data that is measured or represented on a
continuously
varying scale, such as a dimmer switch or a watch with a sweep
second hand.
Compression Correct answers Any technique that recodes the data in a
file so that
contains it
fewer
bits
Lossy compression Correct answers Any data compression technique in
which
the some
data of
is sacrificed to obtain more
compression.
Lossless compression Correct answers A compression technique that
is able to
reconstitute all of the data in the original file; hence lossless
means that this
compression technique does not lose
data.
Compression is commonly referred to as "zipping". Correct
answers True
On laptops and desktop computers, the compression utility is accessed
from the
screen same
used to manage files. Correct
answers True
Pixel interpolation Correct answers A process that is used by graphics
software the
average to color of adjacent pixels in an image, usually when the image
is enlarged.
Data Correct answers In the context of computing and data management,
datasymbols
the refers tothat a computer uses to represent facts
and ideas.
Information Correct answers A computer system that collects, stores, and
processes
information, usually within the context of an
organization.
Bitmap Correct answers An image, such as a digital photo, that is stored as
a grid
of work
colored
dots.
, A bitmap graphic is composed of a grid of tiny rectangular cells where
each cell
picture is a
element, commonly called a pixel. Correct
answers True
Vector graphics include standard shapes such as circles and
rectangles. Correct
answers
True
Vector graphics Correct answers An image generated from descriptions that
specify the
position, length, and direction in which lines and shapes
are drawn.
Vector graphics vs. Bitmap graphics Correct answers Vector graphics resize
better than
bitmaps, require less storage space, are not as realistic as bitmap images,
andobject
an editing is easier than in
bitmap.
Vector graphics are used for line art, logos, simple illustrations, infographic
elements,
and diagrams. Correct answers
True
are based on vectors stored as a set of instructions describing the
coordinates for lines and shapes in a three-dimensional space. Correct
answers 3-D graphics
Ray tracing Correct answers A technique by which light and shadows are
added to a 3-
D
image.
Rendering Correct answers In graphics software, the process of creating a
3-D solid
image by covering a wireframe drawing and applying computer-
generated highlights
and
shadows.
Vectors Correct answers Lines and curves that form simple
shapes.
Vectors form a wireframe that works like the framework for a tent. Correct
answers True
Software Correct answers The instructions that direct a computer to
perform with
interact a task,a user, or process
data.
Application software Correct answers A set of computer programs that
help users
perform a specific task such as word
processing.
The primary purpose of is to help the computer system monitor itself
in order
to function efficiently (an example is a computer operating system or
OS). Correct
answers are System
used for creating software applications, Web sites, operating
software
utilities. systems, and
Correct answers Development
tools
When a computer "runs" software, it performs the instructions to carry
out a task.
