Answer 1

network

Question 2

individual entity in a network

Answer 2

node

Question 3

he connection between nodes

Answer 3

link

Question 4

the study of networks, specifically complex networks

Answer 4

network science

Question 5

The main factor that caused the emergence of network science is:

Answer 5

the internet

Question 6

basically a record of the nodes and links that form a network

Answer 6

network map

Question 7

a network that has a structure and behavior that is neither totally predictable nor completely random

Answer 7

complex network

Question 8

The following are three well known and commonly studied types of network:

Answer 8

1. random network
2. scale- free network
   3.

Question 9

network that follows a probability distribution in the number of links that each node can have

Answer 9

random network

Question 10

a complex network. Its defining characteristic is that it has few nodes with a lot of links and lot of nodes with few links. A node with many links is called a hub

Answer 10

scale-free network

Question 11

the statistical relationship between two quantities in which change in one quantity affects the other

Answer 11

power law

Question 12

a network in which most nodes are not directly linked but any two nodes are connected by short paths. In order to get from one node to another that is not directly connected to travel between two unconnected nodes, you have to go through path composed of other connections

Answer 12

small world network

Question 13
