Create a Code in Python For a node Create a node that creates clusters, the size of the cluster can be any number and it creates a random number of nodes. Each node has a different processing load at the time of the creation of the cluster. Write a pseudo code for the algorithm, where the node selects which data can be processed from the cluster head. Cluster heads can send data any time with any size. The completion time for the data processing task is determined by processing time vs processing load curve.
Task 9 You are asked by your line manager to implement a computer code for solving the following system of linear equations using MATLAB. You need to upload your code as to be assessed as a part of this assignment. 4x1 + 1x2 + 2x3 − 3x4 + 5x5 = −16 −3x1 + 3x2 − 1x3 + 4x4 − 2x5 = 20 −1x1 + 2x2 + 5x3 + 1x4 + 3x5 = −4 5x1 + 4x2 + 3x3 − 1x4 + 2x5 = −10 1x1 − 2x2 + 3x3 − 4x4 + 5x5 = 3 then prove it

Objective Define a circular buffer data structure and test it. Problem Description: A circular buffer (also called a circular queue) is circular list of nodes where data items are added on one end of the buffer and removed from the other end. Because the nodes form a circular list, the list has no end or beginning: the tail node points to the head node, creating a ring of nodes. You may think of the nodes as containers or slots that are all initially empty but can be assigned a value in their data field info. Every time a new data item is inserted (inserting to a buffer is often referred as Writing), one slot is filled and the buffer has one less empty slot. Every time a data item is removed (referred to as Reading), the buffer has one more empty slot. Since the list has no beginning and no end, a pointer (writeIndex) is used to mark the next empty slot to write to and a second pointer (readIndex) is used to mark the next node to read from. The readIndex/writeIndex must be…

Cooperating Processes: Select all of the following statements that are true. Ordinary (unnamed) pipes provide a solution for bidirectional communication between related processes. Mechanisms for inter-process communication enable different processes to exchange information and synchronize their actions. The bounded buffer solution to the producer-consumer problem, which was the first one discussed in class and does not use semaphores or monitors, allows at most BUFFERSIZE items in the buffer at the same time.
The Gantt chart method permits the development of scheduling algorithms that account for all precedence relations when the schedule is developed. True/False
