Consider the following set of processes, with the length of CPU burst in milliseconds. Process PI P2 P3 P4 P5 Arrival time 00 02 03 06 30 Burst time 10 12 14 16 05. Draw a Gantt chart that illustrates the execution of these processes using the preemptive shortest job first (SJF) algorithm. Hence find the average waiting time. Draw a Gantt chart that illustrates the execution of these processes using a preemptive priority scheduling algorithm. Given priority of each process is PI = 4, P2=3,P3=5, P4= 1 and P5= 1. Also, find the average waiting time.

In the context of it jobs in the information systems field. a is responsible for database design and implementation

You have just been hired as an information security engineer for a large, multi-international corporation. unfortunately, your company has suffered multiple security breaches that have threatened customers' trust in the fact that their confidential data and financial assets are private and secured. credit-card information was compromised by an attack that infiltrated the network through a vulnerable wireless connection within the organization. the other breach was an inside job where personal data was stolen because of weak access-control policies within the organization that allowed an unauthorized individual access to valuable data. your job is to develop a risk-management policy that addresses the two security breaches and how to mitigate these risks.requirementswrite a brief description of the case study. it requires two to three pages, based upon the apa style of writing. use transition words; a thesis statement; an introduction, body, and conclusion; and a reference page with at least two references. use a double-spaced, arial font, size 12.
