• Review  contributions to threats and  vulnerabilities on a home network and determine if they have gaps in  their understanding.
• Provide feedback on a classmate’s home  network security measures they are not currently using. Do you have any  other suggestions or recommendations for them?

 What threats do you need to be concerned about on your home network?

There  are a lot of threats for a home network. One major threat for home  networks is computer viruses. These are very common issues that a lot of  people deal with. viruses are very easy to get one wrong click and you  have one. viruses are very dangerous for everyone. viruses can expose  information on the devices they are on and send it to scammers. They  could also slow the device down.

What are the vulnerabilities of each of your devices on your home network?

Firewalls  are the first line of defense for the devices. If there are issues with  the firewalls the devices will be a lot easier to hack and change these  firewalls can be a point of vulnerability if they have issues. Using a  open WIFI network is also a point of vulnerability for devices. Other  people on these open network can get into the devices onto the network.

What techniques can you use to protect your devices on your home  network? (Make sure to discuss how you will protect your network traffic  on your wireless network.)

Make sure you use a firewall on the  router. You should also limit access to the network. If you let just  anybody on the network it raises the risk of getting hacked so you  should only give access to those you trust.

Discuss some home network security measures you are not currently using but may consider using
There  is one major security measure that I do not do yet but will definitely  start soon. I will start using a VPN. VPN’s encrypt your network making  it difficult to pin down the device and track.

Data backups are extremely important. Data ups should be kept off site and secure. Research a backup solution, datacenter or cloud based, and explain the available options, cost if possible, advantages and disadvantages, and if this is for personal or corporate use.

Annette Jackson owns a small crafts store in central Missouri. She wants to expand her store’s reach outside the region to increase her profits and simultaneously reduce her inventory. Annette’s teenage daughter suggested that she consider selling online to expand her total sales. She asked you to help her estimate how much it might cost in the first year to create a simple store with a catalog of about 100 items. Annette wants you to investigate two CSP offerings and report back to her what you find. Because her store is small, limit your research to basic commerce and mall-style services. Annette would like to consider the following information for the two CSP offerings you examine:

NOTE: Please Choose any 4 item form the following list and discuss them ( DISCUSS ONLY 4)

• Costs: initial setup fee, monthly fee, and transaction fees

• Amount of disk space the CSP would provide for Annette’s 100-item store

• Promotion and marketing opportunities

• Customer communications capabilities, such as automated e-mail confirmation of orders

• Shopping cart or other order entry mechanism

• Storefront-building wizards for creating a new store

• Upload capabilities for product names, descriptions, images, and costs (Can they be uploaded from files or databases, or must the merchant enter each item individually?)

• Existence of an online user manual for the merchant

Use your favorite search engine to find CSPs that might meet Annette’s needs. Produce a report of about 400 words summarizing your findings.

Discuss what methodology or subject that you have learned has been your favorite topic/subject? Write a paragraph and briefly discuss and share your learning experience with classmates.

Please list your reference

Choose the 10 best sources from your searches for articles, papers, and dissertations. Focus on sources that give details about your research topic. Next, write the reference list entry (APA citation style) for each source. Alphabetize your list of reference list entries. After you have the correctly ordered list, number your entries from 1 to 10. Note: different reference entry formats are used for different types of sources. Review the UMGC Library’s “Get Help > Citing and Writing for samples and explanations of the formatting rules. If you are using APA format, your list should look something like the following.

1. Authors.      (date). Article title. Publication name, vol(issue), #-#.
2. Authors.      (date). Paper title. Published in the Proceedings of conference-name, pp.      #-#.
3. Authors.      (date). Book title. City, state (or country) of publication:      Publisher.

Next, write your annotations for each source in your list. In an annotated bibliography, the annotation is a paragraph or two placed under the reference list entry for each source. For this assignment, the annotation should be a combination of factual information from the source and your evaluation (opinion) of the quality and usefulness of the information; you will be combining the descriptive and analytical styles of annotations.

To accomplish this, you should read the abstract, introduction section, and closing sections for each article or paper. For dissertations, look over the Introduction and the Literature Review (usually the first two chapters). From this information, develop a short informative or descriptive summary of the source that includes: (a) a description the information provided in the source, (b) how you plan to use this source to support your analysis of your research topic, and (c) your thoughts and opinions about the utility or quality of the source. Each annotation should be approximately 100-125 words (five to seven sentences). Place this summary after the reference list entry for the source.

Project Description:

In this project, you will prepare a chemistry lab report, modifying and formatting an existing document that has been reviewed by your partner. You will also add data tables relevant to the experiment being described.

Start   Word. Download and open the file named Exp19_DSP_Word_Science.docx. Grader has automatically added   your last name to the beginning of the filename.

Ensure that formatting marks are   displayed. Reply to the comment on page 4, typing I will add the conclusions we mentioned   yesterday. (Include   the period.)

Place the insertion point at the   beginning of the document. Add Leslie Pangle after Name,   Dr. Charles Cooper after Lab Partner, and October 18, 2021 after Date.

Adjust the left and right   margins to 1″. Insert an unedited footer and insert a page number at the   Bottom of the page using Plain Number 2 selection, or another page number   entry if that style is unavailable. Close the footer.

Select the entire document and   change the font to Times New Roman, with a font size of 12 pt. Center align   the title (Analysis of Iron in a   Vitamin Pill) and change the font size to 14 pt.

Right align the information   above the title of the paper beginning with Name: and ending with Date:.   Change the line spacing of those lines to single.

Apply the Subtitle style to all of the headings (Abstract, Introduction, Materials, Procedure, Results, Conclusion,   and References). Modify the   Subtitle style to apply Italic formatting and a font size of 12 pt.

Select the list of materials on   page 2, beginning with Spectrophotometer   and ending with Vitamin tablet,   and convert it to a bulleted list using the default bullet selection. Format   the list in two columns.

Draw a text box just below the   list of materials and type Dilution Equation (M1V1 = M2V2). Apply subscript to the numbers in the equation.

Format the text in the text box   to Times New Roman 12 pt.. Remove the outline from the text box and change   the height to 0.3″ and the width to 2.5″.

Change the text wrapping to   Square and apply Align Center alignment to the textbox.

Insert a blank line after the   first body paragraph in the Procedure   section, ending in rinse them out   thoroughly. Insert a table with five columns and six rows at the location   of the blank paragraph.

Merge all cells on the first row   and type Preparation of Standards Solutions. (Do not include the period.)

Enter the following headings and   data, beginning on row 2. Several titles may automatically wrap within cells.
 

Solution mL Stock Iron Solution Drops of Citrate mL Hydroquinone mL Phenanthroline
 1 1 6 1 1.5
 2 2 12 1  1.5
 3 3 18 1 1.5
 4 5 30 1  1.5

Insert a row below the headings   on row 2, type Blank as the Solution type, and then complete the rest of the row with   the following data:
 

Blank  0  0   0   1.5

Change the line spacing of row 2   to Single. Change the height of row 2 to 0.4″.

Format the table using the Grid   Table 1 Light table style. Deselect the First Column checkbox on the Table   Design tab so the first column is not formatted. Center align all cells.

Add a footnote following the mL Stock Iron Solution heading. The   footnote should read Stock iron   solution provided by instructor. (Do not type the period.)

Move to the table on page 4 and   insert a new row above the first row in the table. Type Table 1:   Calibration Curve Data Table. Merge all cells in the first row and apply Align Top Center   alignment.

Format the table to AutoFit   Window and apply the Grid Table 1 Light table style. Deselect the First   Column checkbox on the Table Design tab so the first column is not formatted.

Select the four paragraphs that   follow the paragraph that begins This   table summarizes the results. Convert the selected text to a table with   four columns and four rows.

Insert a new column to the right   of the last column in the new table. Click in the last cell of the first row   and create a formula to average the two trial amounts for the Absorbance of   the Iron Tablet Solution. The formula should average all cells to the left.   You do not need to assign a number format. Similarly, enter a formula in   remaining cells in the last column to average the Mass Fe of Tablet, Mass of   Iron in Tablet, and Percent Error.

Insert a new row above the first   row in the table containing averages. Type Table 2: Iron Tablet Data, merge all cells in the first   row, and apply Align Center alignment.

Center rows 2 through 5 of Table   2. Format the table using Grid Table 1 Light table style.

Using Manage Sources on the   References tab, add a new source using the APA style for a journal article:
  Author: Atkins, Robert C.
  Title: Colorimetric   Determination of Iron in Vitamin Supplement Tablets: A
General   Chemistry Experiment
  Journal Name: Journal of Chemical Education
  Year: 2005
  Page: 550

Insert a page break before References on page 4. Place the   insertion point on the blank line after References. Click Bibliography and select Insert Bibliography to insert   the source (or select another option if that one is unavailable).

Click after the words Preparation of Standards Solutions in   the first row of the table of the same name on page 3. Press SPACEBAR and   insert a solid round bullet symbol located in the Symbol font group. The   character code is 183. Press SPACEBAR after inserting the symbol and type Analysis of   Variables.

Place the insertion point on the   blank paragraph under Conclusion on   page 4. Type the following paragraph, pressing ENTER after typing the   paragraph.
 

The   vitamin tablet was tested twice, and the results were in an acceptable   percent error range. Miscalculations in this experiment can be traced to the   difficulties in measuring the volume in the graduated cylinder and Erlenmeyer   flasks. With experience, technical variations may be overcome. Overall,   the vitamin tablet tested did come   close to the amounts claimed by the manufacturer. 

Insert text from Conclusion.docx.

Check for spelling and   grammatical mistakes. Accept any corrections for grammatical mistakes related   to placement of commas and leaving a space after a parenthesis. 

Select the word analyzed in the second paragraph of   the Conclusion section. Use the   Thesaurus to replace the selection with a synonym beginning with the letter   c.

Open document properties. Add   the keywords: Iron, Beer’s Law, Absorbance.

Save and close Exp19_DSP_Word_Science.docx. Exit   Word. Submit Exp19_DSP_Word_Science.docx   as directed

You need to elaborate and explain. Your grade is going to reflect the completeness, effort, and time you spent on this activity.

In this assignment, you will be modifying the ‘mfs’ (minix file system).

I-‐nodes in the Minix file system contain 3 times – time of file content modification, time of last access, and time that the i-‐node information has been last changed. There is no file creation time stored in the i-‐node. Modify Minix to change the meaning of the ‘last change in i-‐node information’ time to ‘file creation time’. In places in Minix where only the ‘last change in i-‐node information’ changes, make that change reflected in the file modification time. Verify your changes by creating a file, noting the creation time, then modifying the file contents and/or the i-‐node information and checking these various times, assuring that the file creation time does not change (the ‘ls’ command has the options necessary to check each of these times).

you are to simulate a dispatcher using a priority queue system. 



New processes are to be entered using a GUI with priority included

(numbering should be automatic). Processes are also to be terminated

by GUI command. Context switches are to be by command with the cause of the

switch being either a blocking call, time slice exceeded or termination.

Assume only one CPU.



Priorities and numbers of processes can be kept small, just big enough

to demonstrate the required functionality. You may pre-populate the

queues initially from a data file. I am looking at the mechanism as you

are NOT creating actual processes, just simulating them.



Functionality to be provided by you:



1. Priority based Ready Queue(s).



2. Blocked list.



3. Output of complete system status after every context switch showing

   ready, blocked, and running processes.



4. GUI for operations/control/output.
