A directed graph in discrete mathematics, usually refered to as graph theory, is a collection of nodes that represent information/data, connected together by edges, where the edges are directed as going from one node to another rathen than being a simple link.
For example the road network could be depicted as a complex network, and the vast majority of edges (depicting roads) would not be directed, excluding one way streets, due to roads going in both directions.
Whereas the water network running through a city or county or whatever you choose, would be depicted as a directed network as the water can only flow in one direction. Also, sometimes in cases such as these you will get directed magnitude graphs where the directed edges specify the direction of flow and the numbers attributed to each edge show the maximum capacity through that edge/pipe.
we use discrete mathematics in industry and business
Any kind of graph can be used for discrete data.
SIAM Journal on Discrete Mathematics was created in 1988.

A graph composed of isolated points.
Combinatorics play an important role in Discrete Mathematics, it is the branch of mathematics ,it concerns the studies related to countable discrete structures. For more info, you can refer the link below:
It is Discrete Graph .
It can be continuous or discrete.

Find directed graph that has the adjacency matrix Find directed graph that has the adjacency matrix
Yes it is. Discrete data is something that's set. Like say you were making a line graph about renting bikes. You can only rent whole bikes there is nothing in between. You shouldn't connect points on a line graph with discrete data but some cases can be argued. Continuous data is usually a measurement that could change like time.
