A Network is definitely a Tree when any of the below properties matched.
Explanation:
A Network is synonym for connected graph. Connected graph is a graph is a path which will connect from vertex to vertex.
A Tree is a network that has no circuit. network can be differed from tree by three key properties
1. Single path property - one path connecting two vertices
2. All bridges property - every edge of a network is a bridge
3. N-1 edges property - N vertices has N-1 edges
To determine this we use to N-1 edges property as given number of vertices and no bridges.
If a network has 15 vertices it must have 15-1= 14 edges to become a tree
Answer: An operating system(OS) is an interface between the hardware and the user. An OS is built so that it could support other software. OS is a system software which is used to support other application softwares.

The OS is responsible for allocating memory, managing the hardware, distributing resources across different processors in an distributed system.
So all these features makes them different from application software. The OS is responsible allocating memory and hardware resources to these softwares.
