A graph is used to represent discrete objects and relationships between them. It consists of nodes connected by edges, with edges representing connections between nodes. The degree of a node refers to the number of connections it has to other nodes, and a graph can have multiple edges or loops where an edge connects a node to itself.

1. DEFINITION
GRAPH
Graph is used to represent data
consisting of discrete objects
and to show the relationship
between these objects in a
simple graphical manner.
EDGE
It is one of the connections
between the nodes of the
network
Multiple Edges: The vertices are
connected by more than one
edge.
Loops: The edge is in the form of
an arc that starts and ends at the
same vertex.
DEGREE
The number of connections it
has to other nodes
