Simulate the functioning of a network interface. An interface has a MAC address (a String). Computers (threads) send ethernet frames to the network interface input which is a waiting queue. Computers send frames every 1 second. Each frame contains a message and a destination address.

The network interface controller (thread) gets the frame from the queue and checks if the destination address is the same with the network card address. If they are they are different the packet is dropped. If they are the same the controller displays on the screen “Frame with message was accepted. Every 5 seconds the controller outputs on the screen statistics : how many frames were accepted, how many were dropped.

In main test the program with 100 computers, each sending 10 frames and a network interface card. Solve the concurrent access to shared resources using objects lock, wait and notify.

Do a bit of research on CWE, Common Weakness Enumeration.

Write a brief overview of their scoring system.

Pick one of common weaknesses identified on their site and describe it.

Your assignment should be 200-300 of your own words.

This project is pretty much complete, just need to implement a page replacement algorithm to the .c file I have included. The original pdf is attached as well. There is also an expected output after the code is complete to test the project.

Safe Assign is software that verifies the originality of your work against on-line sources and other students.

Note your Safe Assign score. Continue submitting until your Safe Assign score is less than 25.

You will complete this assignment in Python 3.x. Make sure you have downloaded the software and it is installed correctly. You will download it from this site

You will code the following and submit it in one file. Use the information in the Content area for this week to assist you. Save it as a python file (.py), and upload it into the Assignments area.

Create 2 Python programs based on week 5 flowcharts and requirements. You must use loops, do not use function call

Here is a SAMPLE run for a simple calculator to add to numbers (this is for reference only)

Simple Calculator

What is your name –> Supa

Enter first number –> 7

Enter second number –> 5

Supa, The total of 7.0 + 5.0 = 12.0

Do you want another calculation ? (y/n) y

What is your name –> Lupa

Enter first number –> 21

Enter second number –> 11

Lupa, The total of 21.0 + 11.0 = 32.0

Do you want another calculation ? (y/n) n

Thanks for using my calculator

 As you all read, according to Kirk (2016), most of your time will be spent working with your data.  The four following group actions were mentioned by Kirk (2016):

• Data acquisition: Gathering the raw material
• Data examination: Identifying physical properties and meaning
• Data transformation: Enhancing your data through modification and consolidation
• Data exploration: Using exploratory analysis and research techniques to learn

Select 1 data action and elaborate on the actions preformed in that action group.

Please make sure you have an initial post (about 200 words) and a comment/post to one of your friends’ posts.

i just want you to do question no 4 as it is a group assignment.

Overview

To understand and make use of any database system, you must learn various techniques associated with the fundamental operations of create, read, update, and delete (CRUD). For this assignment, you will begin by creating databases of document collections and performing basic reading or querying operations to retrieve specific documents from the database system. You will also gain practice updating documents and subdocuments, and removing documents from a database. You will use the mongo shell and mongoimport commands to complete this assignment.

Note: Since this is the only assignment for Module Two, it is longer than a typical assignment. Be sure to begin working on this early in the week.

Prompt

After completing the textbook reading and reviewing the mongoimport tool documentation in the module resources, complete the following tasks using the mongo shell in Apporto.

1. The data set for this assignment, city_inspections.json, has already been loaded into the Apporto environment for you. Using the mongoimport tool, load the database “city” with documents found in the city_inspections.json file into the “inspections” collection. Complete this by typing the following commands in the Linux terminal to perform the import in the right directory:
   cd /usr/local/datasets/ #change into the Apporto directory with the data sets mongoimport --db city --collection inspections ./city_inspections.json #mongo import utility
   TIP: In any Linux systems, commands must be exact and use proper syntax and case sensitivity.
2. Verify your load by switching to the “city” database and issuing the following queries in the mongo shell:
   1. db.inspections.find({"id" : "10021-2015-ENFO"})
   2. db.inspections.find({"result":"Out of Business"},{"business_name":1}).limit(10)
   3. Provide screenshots of the results as evidence.
3. Using the appropriate commands in the mongo shell, insert a document to the database named “city” within the collection named “inspections.” Use the following key-value pairs as data for your document.
   KeyValueid“20032-2020-ACME”certificate_number9998888business_name“ACME Explosives”dateToday’s dateresult“Business Padlocked”sector“Explosive Retail Dealer-999”addressnumber -> 1721
   street -> Boom Road
   city -> BRONX
   zip -> 10463
   Be sure the address is inserted as a sub-document, and use the JavaScript function Date() for “Today’s date.” Verify your database creation and insertion using the findOne() function in the mongo shell. Provide a screenshot as evidence.
4. Answer the following questions using MongoDB queries.
   1. What is the distinct list of inspection “sector” in the current inspections collection? How many are in the list? Do not count by hand.
   2. What is the difference in the date data type for the business named “AUSTIN 2012” versus your business document insertion of “Acme Explosives”?
   3. How many businesses have a “Violation Issued”? (See Value column above.)
   4. Verify by providing screenshots of the queries and results as evidence.
5. Using the appropriate command in the mongo shell, update the document with the ID “20032-2020-ACME” in the collection “inspections” in the database “city” with the information below.
   KeyValuebusiness_name”New ACME Flowers”result”Business Re-opened”comments”Flowers after the explosion”
   Verify your database update using the appropriate find() function in the mongo shell. Provide a screenshot as evidence.
6. Using the database “city” with documents found in the “inspections” collection, perform the tasks listed below. Verify by providing screenshots of the results as evidence.
   1. Update all the documents that contain the key-value pair “city”:”ROSEDALE” in the address subdocument by changing the zip code in the address subdocument to “76114”.
   2. Remove the first document with the key-value pair “result”:”Violation Issued.”
   3. Guidelines for Submission
      Submit a Word document containing all of your screenshots. Use a screenshot tool, such as the Snipping Tool, for your screenshots and be sure to enlarge the images in the Word document before submitting. This will help make sure that your screenshots are an appropriate size for your instructor to be able to read them. Refer to this Use Snipping Tool to Capture Screenshots guide for help with taking screenshots.
