Point-to-point topology directly links two nodes together. Point-to-point is east to implement. It has higher speeds when compared to other topologies because only two nodes are using the link. However, if the link fails, the network goes down. A bus topology has all of the devices on a network on a single cable running in one direction from one end of the network to the other. Bus topologies are a cost-effective choice for smaller networks since all of the devices are connected by a single cable. If the cable experiences a failure, then the whole network goes down. A ring topology links each node with another node to form a closed network. Data moves from one node to another in this topology. Ring topology’s circular flow of data minimizes packet collisions and can it can also handle a large number of nodes and heavy traffic. A single failure of a cable in a ring topology can disrupt the overall network operations. In a star topology, all nodes are connected to a central hub using a communication link. Every node needs a separate wire to establish a connection with the hub. Since each node has its own cable, network maintenance and management are easier. It is easier to add new devices in a star topology. If the central hub fails, it brings down the entire network. In a mesh topology, all of the nodes are interconnected and can send and receive their data from other nodes. Mesh topologies are redundant because if there are any failures in the nodes or links, it only affects a minimum number of endpoints. Mesh topologies are costly to implement and the installation and maintenance can be time-consuming. 

At the healthcare agency I worked at, they used a star topology. I think this worked best for that office because it was a small office. There weren’t too many people that worked there. There was one day where the central hub failed and no one in the office could use their computers. Even though nobody could work that day, I believe that a star topology was the right choice. This was in the middle of hurricane season in Florida and it had been raining for a few days straight. 

  Write an algorithm for the add method that will add at the end of the list instead of the beginning. What is the time complexity of this algorithm? 

Modify the algorithm from the previous exercise so that it makes use of a rear reference. How does this affect the time complexity of this and the other operations?

Word Chapter 3 Cumulative – Tourism

Project Description:

As a member of a local chapter of the Audubon Society, you are involved with an outreach to promote ecotourism, which encourages travel to natural habitats while conserving the environment in the process. You will finalize a short flyer that identifies eight unique destinations for ecotourism, describing them in a Word table. Business sponsors have agreed to support the effort and will be distributing flyers, so you plan to include each business name and contact in the flyer.

9  190,000
10 3,500
7 145,000
8 348,000

Select the first table. Select a   border style of Double solid lines, ½ pt, Accent 3 (row 3, column 4). Apply the selection to outside   borders. AutoFit contents of the table

Select the first row of the   first table and merge cells. Center text in the first row. Apply shading of   Light Gray, Background 2, Darker 50% (row 4, column 3). Change font color of text in the   first row to White, Background 1. Bold text in the selected row and change the font size to 14.

Select rows 2 through the end of   the table and apply shading of Light Gray, Background 2 (row 1, column 3). Use Border   Painter to copy the double-line format from an outside border and apply it to   each vertical gridline within the table.

Apply Align Center alignment to   all text in the second row so that contents are both horizontally and   vertically centered. Apply Align Center alignment to all text in the first   and third columns. Select all numbers in the last column and apply Align   Center Right alignment.

Include a caption that reads   Table 1:   Data provided by the National Conservation Fund below   the first table.

Select rows 3 through the end of   the first table. Sort the rows in ascending order by Column 1. All   destinations should be shown in alphabetical order.

Insert a row at the bottom of   the first table. Type Average in the second cell on the last row. Choose Align Center Right   alignment and bold the entry.

Include a function in the third   cell on the last row (below the C2   Rating column) that determines the average of the values in the column   above. You do not need to select a number format.

Include a function in the last   cell on the last row (below the Approximate   Visitors/Year column) that determines the average of the values in the   column above. You do not need to select a number format.

Wk 12 Lab Assignment

In this week’s discussion, you were introduced to Wireshark and GlassWire, two free network monitor & security tools. Compare and contrast these two tools. explaining the benefits and features of each, then decide which of these two choices you would prefer to use if you were the Network Manager. Explain why you made your decision.
https://www.glasswire.com/https://www.wireshark.org/ 

Each week you are to enter content into an online journal provided in Blackboard that briefly summarizes (1) the tasks you performed during your internship that week and (2) total hours worked with days/times. The content can be brief and in outline form and use bullet or another list styling, but keep in mind that this content will form the basis of the two major papers that you will write for this course. Therefore, the more detailed you are in your weekly journal, the easier it will be to finish the two papers. Specifically, your weekly journal should contain: 

• The days and times you worked that week, as well as the total hours, worked. (Provide this information at the top of each weekly section so this will act as a de facto heading to separate each weekly entry that you make.) 

• The skills or skillsets used/required to complete each task 

• Each task you performed along with a brief description of what you did.

 • A brief explanation of why the task needed to be done.

 • Was there an outcome? If so, what was that outcome?

 • What new terminology did you learn this week? Provide the term and its definition.

Operational security compliance is a necessity in any working cybersecurity environment, as it sets the standard for policy, rule, and guideline regulation. Therein, it is necessary for security professionals to grasp the fundamental aspects of operational compliance if they are expected to be able to manage day-to-day operations that require a different level of compliance throughout a given organization.

Students will create a web portal data flow diagram of their hypothetical organization’s operational environment using Visio or similar diagramming software. Within the web portal data flow diagram, students will show how the web portal is compliant. The web portal data flow diagram must:

1. Display the organization’s technical requirements (related and unrelated applications, services, and links).
2. Display the compliance of associated servers, routers, access-control components, data storage, internal and external data communication, data backup, e-mail servers, and so forth.
3. Identify related systems and assets, regulatory requirements, and overall risk approach.
4. Demonstrate each IT task to the next as aligned to regulations/compliance. For example, start with the user logging in, and then go through each step and how it is validated.

APA style is not required, but solid academic writing is expected.

Refer to “CYB-650 Operational Compliance Scoring Guide,” prior to beginning the assignment to become familiar with the expectations for successful completion.

Read the Equifax Data Breach case and write a paper answering the following the following three questions:

1. Discuss the moral issues in this case and whether Equifax’s actions constitute a moral failing.
2. Should companies like Equifax be compelled to announce data breaches to the public within a certain time frame (e.g., 72 hours after discovery)? What would be the downside of legalizing such a requirement?
3. In your opinion, why was security so lax at Equifax and how can this laxity be remedied?
