CPSC 100 Exam Graded A+ Verified
Ambiguous task - ANSWER-- Input - variable
• Mode of evaluation - subjective
• Output - clear or variable
example: determining who gets a loan
Animation - ANSWER-"to give life to"
-An animator takes a static image or object and literally bring it to life by giving it
movement and personality.
•In computer animation, animators use software to draw, model and animate objects
and characters in vast digital landscapes.
arc diagrams - ANSWER-Alternative way to represent two-dimensional network
diagrams. The downside: they don't show structure and connections between nodes as
well as 2D charts & too many links can make the diagram hard to read due to clutter.
Area chart - ANSWER-Area Chart are line graphs but with the area below the line filled
in. Used to show trends rather than convey specific values.
Good for
-Distribution
-Trend over time
ASCII - ANSWER-In addition to letters and numbers, punctuation, spaces and other
special control characters are encoded; each encoded item is sometimes called a code
point
•Why 7 bits? An extra "check" bit was included that could be used to detect certain
errors that might arise, e.g., when sending data over a modem
•Extended ASCII uses 8 bits (or one byte), allowing for characters with accents (Á, ë
and others)
assembler - ANSWER-translates from Assembly language to Machine Code
Bar charts - ANSWER-Good for Comparisons
Bar charts do not display continuous developments over an interval. Bar chart's discrete
data is categorical data and therefore answers the question of "how many?" in each
category
Binary - ANSWER-base 2. In binary, every column is worth 2times as much as the
previous one
bit - ANSWER-short for a binary digit.
, bitmap - ANSWER-the picture is chopped up into small little squares called pixels.
Each pixel is stored in RGB.
a bitmap image representation must specify
•The number of rows and columns in the grid of pixels
•The RGB colour specification of each pixel in the grid, say from top left to bottom right
Breaking down the files - ANSWER-http://imgs.xkcd.com/comics/phishing_license.png
http:// --> protocol
ings.xkcd.com --> domain
/comics/ --> directory
phishing_license.png --> file
Everything after a "?" is data needed to process the request. In this case, it's the ID of
the comic that the user has requested.
Bubble chart - ANSWER-Is a multi-variable graph that is a cross between a scatter plot
and an area chart.
It uses the Cartesian coordinate system to plot points on a grid. X and Y are separate
variables
Uses size to represent another variable
And possibly it can also use color
4 variables
Good for Comparisons, Trends over time, Distribution, Proportions, Relationships
Limitations Area for comparison is not good
Cache - ANSWER-fast memory that is actually on the chip. Second smallest
circular dendrogram - ANSWER-Used for showing • Hierarchy • Relationships
Limitations • Space
Classification - ANSWER-Classification involves using previously grouped data to
determine how to group new data.
Examples • Loan strategy • Soccer league decision to cancel games
In the Algorithms module, we developed classifiers using decision trees
Classifiers/ Classification - ANSWER-Classifiers are derived from patterns or
correlations from data.
The idea behind classification is that we want to use patterns and/or correlations to
make decisions.
