Description
Computers store and communicate in the binary (base 2) numeration system. Humans, on the other hand, communicate in the decimal (base 10) numeration system.
Discuss the difference between these two numeration systems. Name the binary digits of a Base 2 system and describe the meaning of the 8 bit number 10001111. Convert this number into Base 10, Base 16, and explain the steps involved.

Completed Unit 5 1.) Select three certifications and discuss the type of individual who may be interested in pursuing each one. 2.) Describe the typical duties of a security manager that are strictly managerial and not technical in nature. 3.) Describe the three categories of information security professionals. 4.) Describe the role of due care and due diligence in terms of their role in reducing liability exposure. Requirements: - Learner successfully applied critical thinking to the case study analysis & recommendations/actions taken. - Learner successfully incorporates a minimum of two per question scholarly sources to support their position. (No more than 10% of the entire submission should be from referenced sources. In other words, the references should support the learner’s work not be the bulk of what is written). - Learner met the criteria for academic writing (i.e. no spelling or grammar errors, properly formatted paragraphs, APA formatting used for references, etc.). - Learner met per question 300 word count minimum. One reference can be the reading material that is provided. Whitman, M. E., & Mattord, H. J. (2013). Management of information security (4th ed.). Stamford, CT: Cengage Learning.

System Analysis and Design About ROI and NPV Campus Bike Mini Case Study
Mini Case: Campus Bikes
In Chapter 6, you learned that Campus Bikes is a popular bicycle shop located near a major university. The shop sells several brands of new bikes, including everything from high-end racing models to beach cruisers. In addition to sales of new bikes and accessories, Mark’s service department is always busy. The staff includes Mark himself, a bookkeeper, two part-time sales reps, a full-time mechanic, and several part-time service helpers who assemble bikes.
Background
Until now, the owner, Mark Turner, kept the business records on his personal computer. He cre- ated a simple database to keep track of inventory, but it is not always up-to-date. He also developed spreadsheets to track expenses and payroll. The business has grown and Mark wants to install a new computer system to handle all business functions.
You are a lab assistant in the computer information department at the college. You earned
a computer science degree at a two-year school, and you recently decided to work toward your four-year degree. Mark recently asked you to help him plan a system for Campus Bikes. You used an object-oriented approach to create a model of the business functions and actors involved.
Now Mark wants you to do a “make or buy” analysis. Specifically, you will look into the pros and cons of in-house development versus purchase of a software package. Your research indicates that the most popular bike shop package is offered by a vendor called BikeData.
In your last meeting, Mark said that tangible savings for a new system would be hard to measure, but improved customer care, better service department records, and increased productivity are expected. Mark estimates that these benefits will add up to about $3,000 per year, whether the system is developed in-house, or purchased from BikeData.
You decide to compare relative costs to establish a total cost of ownership (TOC) over the use- ful life of the system. Based on your research, you put together the following summary:
Costs for Option A: Develop In-house
The system will have a six-year useful life, be very flexible, and easiest to maintain.
It will cost $15,000 to develop, install, and configure the system, and $1,000 to load existing data.
Mark and the bookkeeper can handle day-to-day support with no added expense.
Costs for Option B: Purchase BikeData Software Package
This is a vertical package with a four-year useful life.
The software is less flexible than an in-house system and some customizing will be needed.
It will cost $8,000 to purchase, $1,500 to install and configure, $2,500 to load existing data, and $1,000 additional hardware will be needed
Support is free for the first year, then there is a $2,000 annual fee
Benefits for Both Options: $3,000 per year
Tasks
(30 pts) Prepare a detailed list of pros and cons of in-house versus software purchase.
(20 pts) Calculate ROI for both options.
(20 pts) Calculate NPV for both options. Use an 8% discount factor.
(30 pts) Create one sheet word document for Mark showing the results of your analysis, including recommendations and reasons.

ITS 4105 Computer Science Remote Accessing and Related Issues Paper
Part A
Remote Accessing and Related Issues
An organization's head office is connected to its branch office over the Internet. The network connection works fine without errors. The users at the branch office connect to the head office by using telnet to access UNIX-based servers and a virtual network console (VNC) to access Windows-based servers. They transfer data across the network by using FTP. However, the users complain of a mismatch in the content sent from the head office and that received by them at the branch office.
Based on your understanding of the above scenario create a Microsoft Word document, answering the following:
What can be the cause of the problem? Suggest some ways to resolve the problem.
Which is the best way to resolve the problem and why?
Users from the finance department access an Oracle server for their operations. The computers on the finance department network are assigned public IP addresses. The Oracle server is on a different network than the finance department network. The users complain of slow response from the Oracle server. A detailed observation of the traffic flow in and out of the server shows a large number of ICMP echo and echo-reply packets. Consider that you are part of the network administration team of the organization. Imagine yourself as a network administrator.
Based on your understanding of the above scenario, create a Microsoft word document answering the following:
How will you resolve the problem?
Which would be the first place that you would look at for excessive echo and echo-reply packets?
Explain in detail of the various commands and in what order you would diagnose to efficiently pinpoint the issue in quickest possible time.Many users on the local LAN are facing a slow response from the Oracle server. The management has asked you to produce the response time and throughput statistics between a user's computer and the server.Based on your understanding of the above scenario, create a Microsoft Word document answering the following:
Simulate the scenario in Etherpeek and generate the required report.
As part of the technical proposal, document the troubleshooting tools to be used and list the steps to be taken in case of a problem.
Discuss the different problem scenarios that the client may face.
Part B
IP Security and Attacks
Based on your understanding of networking concepts, create a report in a Microsoft Word document answering the following:
Describe 'The Three Principles of IP Security'.
Cite references as well as a detailed explanation for the same.
Explain how you would as an employee of a company practice those principles.
Describe 'Typical IP Attacks' that happen in networks around the world.
Cite references for three different types of attacks that occurred recently (with current and past year) in the news.
Explain how the attack occurred and what was needed to remedy the situation.
