In the following example, there are five processes, P1, P2, P3, P4, P5 and three resourcetypes A (with 10 instances), B (with 5 instances) and C (with 7 instances). The Available, Allocation andMAX matrices are given as: AVAILABLEABC322 ALLOCATIONABCP1010P2200P3302P4212P5002 Copyright © 2015-2021 VIT, All Rights Reserved. 3ITSA2003 Assignment MAXIMUMABCP0744P1121P2500P3010P4431 A. Compute the need matrixB. After calculating the Need matric, show that the current state is safe by showing a safesequence of processes.Question 2: Process Scheduling AlgorithmsExplain different types of process scheduling algorithms. If you have a very long process and shortprocesses keep coming up then names any of these algorithms which leads to starvation.A. Using the round robin algorithm with quantum=2 and 4, you are required to perform thefollowing tasks:i. Develop Gantt Chart showing execution of the processes given in the following table.ii. Calculate Average Waiting Time for the following processes.

Explain all the steps which are a part of REACT Methodology.B. What are the differences between functional component and class component?C. What is Redux Thunk used for?Question 4: An antivirus is a kind of software that is specially designed to help the user’scomputer to detect the virus as well as to avoid the harmful effect of them. In some caseswhere the virus already resides in the user’s computer, it can be easily removed by scanningthe entire system with antivirus help. Explain this statement briefly.
