Need help with Information Systems and Technology question for using NSLOOKUP Query on MacBook Air. I’m having difficulty getting the correct Query search on my terminal application.NSLOOKUP questionsIn this section, you are going to use your own computer to do some direct querying of DNS servers. To start, use Google to determine the locations to lookup. On a Windows computer, open a command prompt on your personal machine by going to start/run and typing CMD then pressing Enter. For a Mac, use the `Terminal` application in Macintosh HD->Applications->Utilities->Terminal. Once you have the command line open, you can issue nslookup commands simply by typing them in at the command line.Run nslookup to obtain the IP address of some web server of your choosing. Make sure to report the web server’s IPv4 address, not the IP address of the DNS server that responded to your request. Paste a screen shot of the results into your report to supplement your answer.Make an nslookup query for a university in Europe to find its “authoritative” DNS servers. (hint, execute the nslookup command with the -type=NS option on just the last two parts of the named address – like nslookup -type=NS www.sjsu.edu) Paste a screen shot of the results into your report to supplement your answer.Make an nslookup query using your primary DNS and an alternate server for mail.yahoo.com. Since most organizations now restrict their DNS servers to internal use only, try one of the open DNS services listed on this Free and Public DNS Servers List (Links to an external site.)Links to an external site.. Compare the results you get when querying the address for mail.yahoo.com on a DNS server from the United States vs. one from Europe or Asia. Provide a screen shot of your results. Why do you think you might get different results from different parts of the world?Hint: the command looks like nslookup mail.yahoo.com xxx.xxx.xxx.xxx where the xx’s are the named address or IP address of some other DNS Server.
EE285 Lab 9 :Real Time Note Tuner In this lab, you will write code that continuously reads blocks of data from the PicoScope 2205 and outputs the data to standard output. Your output should be suitable for piping into your spectral program from Lab 8. In the event that your spectral program did not work correctly, one has been provided for you on Blackboard. In a nutshell, you are writing a program to replace your note generator from Lab 3. The user and programming manual has been linked on Blackboard, and you will need it to finish the lab. Before you begin, use the User and Programming Manuals to answer and turn in the following questions:Should you be using AC or DC coupling for our musical note tuner?2. What voltage range should you use? It may be helpful to look back at the output of the Windows PicoScope software to determine this. 3. Will we need to use triggering? Why or why not?4. Why will we be using block mode for our application instead of streaming mode?5. You will need to specify a “timebase” so thePicoScope knows how many samples totake per second. What is the timebase for sampling rates of 1500 Hz, 3000 Hz, and 6000 Hz? The equation is frequency = MaxSamplingRate / (2 * timeBase). You can get the max sampling rate from the User Manual; assume that only Channel A is active. Once you have answered those questions, you can begin to write your software. Your lab virtual machine should already have the Picoscope drivers installed to /opt/picoscope, but if that directory does not exist, follow the instructions at www.picotech.com/linux.html to install them with apt-get. Download the ee285pico.h header file and the build.sh script file on Blackboard. The first file contains a function you will need in this lab and the second one contains a script that will make compiling your program easier.You will need to run the following command to make the script executable: chmod+x build.sh Create a new C program and include the header file and make sure it compiles (using the command towards the end of the lab manual) ee285pico.h contains a function called kbhit(). It returns true if the user has pressed a key and false at all other times. Have your program read blocks of data and output them to standard output until the user presses a key. In the programming manual, go to Chapter 3 and read up on the general procedure for interfacing with the PicoScope. Follow this general procedure as well as the steps listed in the rubric, as these will help you design your program. You will use the answers to the above questions in order to determine what to pass to the functions as you call them. You can assume that you will always be taking in blocks of 8000 and using a sample rate of 6000. You will need to make sure that your program outputs data in a way that your spectral program can read it. If you are using your own version of the spectral program from Lab 8, you will need to remove the two fgets lines from the spectral program that absorbed the comments generated by Lab 3 as your Lab 9 code will not need to create those lines. Because you are piping data into your spectral program, you normally would not be able to directly print to the screen. However, using the function fprintf(stderr, str, …) where str is your format string and the … are your optional variables like in a printf statement, you can bypass this pipe and print directly to the screen. This is very helpful when you are trying to debug. Additionally, we would like you to use this to print out errors in your program if they are encountered such as no oscilloscope being found, an error happening while opening the oscilloscope, and so on. In the event that one of these errors happens, your program should print out what the error was and quit immediately. You will compile and run your program as follows: ./build.sh lab9.c ./ picoscope | ./spectral n 8000 s 6000Here is my musical note generator code:#include

Using the Internet and other appropriate references, locate information on a hardware or software IDS and/or IPS product or appliance that has not previously been discussed. (Here’s a site to get you started: http://sectools.org/ids.html.) It may be a software program, a security appliance, or a router that has the ability to do intrusion detection. You should pick and discuss IDPS products, NOT firewalls. (Make sure you know the difference.) Describe your IDS/IPS and its capabilities and explain how it could be used in a secure network to provide protection. Include how well the IDS/IPS could work in a typical businessenvironment. Include information on its functionality and limitations based on what you learned in the reading. Please don’t give only marketing fluff, but substantive information about the product, service, appliance, or software.
You are responsible for managing Windows updates on 80 Windows 10 Enterprise computers at the office. Right now you receive alert notifications when a new critical or security update is available for approval. Once you approve the updates, they are eventually installed. You would like these updates to apply automatically for the Windows 10 computers, and ensure that they are applied within 1 day of approval. How can this be accomplished with Intune? How can you confirm that your workstations are applying the updates as expected and present a detailed bi-weekly report to your CEO?

Rewrite the sentences so that they are properly punctuated according to the rules for hyphen usage. As Mr. John Oakhurst, gambler, stepped into the main street of Poker Flat on the morning of the twenty third of November, 1850, he was conscious of a change in its moral atmosphere since the preceding night. (Bret Harte, “The Outcasts of Poker Flat”) Next, he gathered dry grasses and tiny twigs from the high water flotsam. (Jack London, “To Build a Fire”) For a week last September, migrating red winged blackbirds were feeding heavily down by the creek at the back of the house. (Annie Dillard, Pilgrim at Tinker Creek) They lived in a forlorn looking house that stood alone, and had an air of starvation. (Washington Irving, “The Devil and Tom Walker”) [She] had kindled the callow fancy of the most idle and shiftless of all the village lads, and had conceived for this Howard Carpenter one of those absurd and extravagant passions which a handsome country boy of twenty one sometimes inspires in a plain, angular, spectacled woman of thirty.

Questions 7–15: Write down the personal pronouns in each sentence. Tell whether each pronoun is in the first person, second person, or third person. (Reminder: Possessive pronouns are personal pronouns.) 7. We decided to take our vacations together. 8. They took theirs at a later time last year, but this year they will take it earlier. 9. I took mine quite early last year, but that can be changed, too. 10. Your vacation was shorter than you intended. 11. Do you think it could be a little longer this year? 12. Between you and me, the friends were not sure they liked it, but they agreed to take a vote anyhow. 13. We gave them paper and a pencil, and each wrote down her suggestion and gave her reason for it. 14. Each friend read her own suggestion. 15. I don’t know how it happened, but they both had the same idea, and now we are going backpacking in the nearest mountains.
