CMN 170V FINAL EXAM LATEST
UPDATE WITH ACTUAL QUESTIONS
AND ANSWERS RATED A+
Timeless time refers to the fact that: - ANSWER >>>>>the
combination of synchronous and asynchronous information
processing allows to negate sequence.
T/F: Distance is NOT really anymore a fundamental limit to
information exchange. - ANSWER >>>>>TRUE
Information is always: - ANSWER >>>>>Physical! You have a choice
to keep it or delete it.
What's the difference between the Internet and the world wide
web? - ANSWER >>>>>The Internet is the physical infrastructure
and the world wide web is a generic service.
Hyperlinks: - ANSWER >>>>>allow Web to operate along the same
lines as our thought patterns.
Social Network Analysis: - ANSWER >>>>>applies to all kinds of
social networks, also offline, for example when you think about
whom to go to the movies or who is in your family.
Six Degrees of Separation: - ANSWER >>>>>It takes 6 degrees to go
from one person to another person to know each other. Facebook
average path length is 4.7 degrees
small world phenomenon - ANSWER >>>>>We are all linked by
knowing someone. The phrase "what a small world" when
someone you know knows someone else that you know is not too
,surprising knowing 6 degrees of separation connects you to
everyone on Earth.
Homophily - ANSWER >>>>>"Birds of Feather, flock together"
people with similar characteristics hang together.
Without any information about a facebook user beyond a list of his
friends, one can accurately predict sexual orientation.
network centrality - ANSWER >>>>>Degree Centrality: most
connected.
Closeness Centrality: closest to all (reach all others. more quickly:
few steps with all others)
- counts the "degree of separation"
Betweenness Centrality: On the paths connecting all . Sum of
shortest paths through node/all shorten paths.
Eigenvector Centrality: friends of friends (it's all about who you
know). Proportional to sum of neighbor's centrality. Google's
PageRank.
"Space of Flows" - ANSWER >>>>>In digital age, what matters is
not geographic space, but network space.
Space is defined by where you are in the network and who you
communicate with in the network.
LECTURE: The concept of the "space of flows" refers to a
reconceptualization of space due to (among other things): -
ANSWER >>>>>Faster communication, more possible
, communication directions, and an increased importance of your
location in the network.
Network Externalities - ANSWER >>>>>Shapiro and Varian, "When
the value of a product to one user depends on how many other
users there are, economists say that this product exhibits network
externalities or network effects."
Negative network externalities: The value of the product decreases
with the number of people who use it.
Information networks experience positive network externalities
because the more people that use it, the more benefit for
everybody. Think of instagram, an online social media platform,
where the more users provides more content which increases
attention and ultimately make the product more valuable.
X Nodes: X^2 - X Degree
economies of scale - ANSWER >>>>>the more you produce of a
product, the cheaper the product becomes.
In digital products, most costs are related to FIXED COSTS.
"cost" can also be "time investment" (of writing several letters,
etc). The interesting part about digital products is that fact that to
create a single product, an example, a song file, might be a fixed
cost of X amount of dollars. To share, download, or transfer that
song file, it is simply a copy and paste of code as much as you want.
Therefore, no marginal costs or variable costs are involved because
you can compute as many replications of a digital product with a
click of a button and it will cost nothing. Only the initial FIXED cost
will cost you.
