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:
UTF-8 and ASCII both are the character encoding.
In a system,every character has some binary representation,these are the method to encode them.Earlier only ASCII was there, for every character it uses 8 bits to represent.In ASCII only 8 bytes were there i.e 2^8 that is 256.We can't represent number beyond than 127 so it generate a need for other encoding to get into,these drawbacks lead to Unicode,UTF-8.
As ASCII codes only uses a single byte,UTF-8 uses upto 6 bytes to represent the characters.So we can save characters which are as long as 2^48 characters. We can read this encoding easily by the help of shift operators and it is also independent of byte order.
As messages on internet were transferred over 7 bit ASCII messages,so many mail servers removed this encoding.
Polymorphism is malware's ability to change the way it appears on different computers. This makes it very difficult for antivirus software to identify the malware.
