- A star configuration of a network represents its structure as a graph with an edge from a single, central node to each remaining node. A point-to-point configuration represents a network as a complete graph. Draw a picture of an example of each kind of configuration with four nodes, and use big-O notation to state the efficiency of adding or removing a given node in each type of configuration. You can assume for now that removing each edge is a constant-time operation. *PythonThe wait-for graph represents A. Relations betwenn diffrenet processes B. Relations between diffrent resources C. Relation of OS with different resources D. All of the answersQuestion 1. Describe differences between breadth-first and depth-first searches and provide a sequence for each of the searches for the following graph: A / \ B C / / \ D E F Question 2. For the graphs shown below, provide at least 2 BFS and 2 DFS Traversal Paths for each. See starting nodes in bold below for each graph.

- You'd like to study social networks. Consider the following 26 people {A,B,C,...,X,Y,Z} in a social network graph. (These people can be thought of as "nodes" or points drawn on a piece of paper.) Here, we'd like to model "followers." How many different ways can we draw arrows between two people from these 26? Here, "A-->B" (A is a follower of B) is not the same as "B-->A" (B is a follower of A). Order matters here. Enter your answer as a whole number.Imagine a database that is structured like a tree with its roots at the top. Imagine for a moment that we decided to add a fake vertex in between each pair of existing vertices. Demonstrate that adhering to the tree protocol on the new tree yields superior concurrent results to adhering to the tree protocol on the initial tree.9) Given the following graph and the source node F (the 1st node to be discovered), which of the following could be the 3rd node to be discovered during a DFS? A. A B. E C. B D. J E. All

- What are the basic facts about deadlock situation in resources-allocation-graph?Given an n-ary tree of resources arranged hierarchically such that height of tree is O(Log N) where N is total number of nodes (or resources). A process needs to lock a resource node in order to use it. But a node cannot be locked if any of its descendant or ancestor is locked. Following operations are required for a given resource node:Lock()- locks the given node if possible and updates lock information. Lock is possible only if ancestors and descendants of current node are not locked.unLock()- unlocks the node and updates information.How design resource nodes and implement above operations such that following time complexities are achieved.Lock() O(log N)unLock() O(log N)Part b : -Let's say you are running the lock/unlock in a multi core machine. Now you want to let multiple threads to run lock() simultaneously.As we saw in part A, locking a node has multiple validations inside. Will doing lock on two nodes cause a race condition.If yes, how will you solve it.In short, how do make…Finding CommunitiesLet’s consider the following graph presented in Figure 2.30 to demonstrate the community detection algorithm. This graphhas 13 nodes and 15 links. Link weights in community detection is crucial and defines the recursive partitioning of the network into subgraphs. The links in this network are first considered undirected. Multiple algorithms will be used andtherefore, different communities will be detected.
