UCLA COMM 156 Midterm Exam Questions
And Answers 100% Solved.
What is a network? - ✔✔✔ - A mathematical model of interactions comprised of nodes and
links
How to describe links in a network - ✔✔✔ - 2 nodes are connected if...
Degree - ✔✔✔ - the number of links connected to a node; measurement of a node; most
common degree is 1 (one connection)
Component - ✔✔✔ - a subset of the network in which every node is connected to every other
node through some chain of links
Giant Component - ✔✔✔ - The largest component; the size of the Giant Component is equal
to the largest group of people you could possibly reach by starting at one person
Allen Curve - ✔✔✔ - As distance increases, the probability between 2 people communicating
with one another decreases
bipartite network - ✔✔✔ - the nodes can be divided into two
groups so that all connections go from one group to the
other (ingredients & chemical components example)
Directed network - ✔✔✔ - links have a direction to them but they don't go both ways

, UCLA COMM 156
Projected Network - ✔✔✔ - give two different networks that each only have one type of node
(ingredients connected if they both have the same chemical compound of flavor)
Weighted Network - ✔✔✔ - different edges have different
weights depending on the strength of the connection
Homophily - ✔✔✔ - Nodes tend to connect to other nodes that are similar to them
Network communities - ✔✔✔ - subgroups of the network with lots of connections within the
groups and not too any between groups
Dispersion - ✔✔✔ - connected to different network communities
Contagion/ diffusion - ✔✔✔ - how things spread
Influence - ✔✔✔ - an individual's behavior affects the behavior of his/her network neighbors
Network Dynamics - ✔✔✔ - ways in which a network changes
Tie formation - ✔✔✔ - Similar individuals form ties (homophile) -Having similar behaviors can
cause you to make friends (ex make friends with ppl because they are smoking in areas with
you, you spend time together there
Tie dissolution - ✔✔✔ - Dissimilar individual dissolve ties
