For each measure, provide an intuition for the kind of centrality it captures. (Assumethat the measures are being computed for nodes in an unweighted, undirected network.)Your colleague continues,  create a network that captures how oftenour salespeople go on sales meetings together. In other words, two salespeople are linked ifthey attended the same pitch meeting for a client. And the more meetings they attendedtogether, the stronger their link should be.” You realize you need to provide your colleaguewith an explanation of different types of networks.2. How would you describe the difference between a directed and undirected network?3. How would you describe the the difference between a weighted and unweighted net-work?4. Given the type of network your colleague has described, what kind of network wouldyou advise creating (directed or undirected? weighted or unweighted?)
