    New to Networking/Programming and I Need Help!


    I hope this is the right place to turn, I'm really at a loss. I am currently enrolled in an Introduction to Networking class at my college, and what I have come to learn over this semester is that jumping into any kind of computer IT program is hard enough, but with an online course with book learning only and no hands on, I am completely lost. I just need to make it through the last bit, and there are certain parts of assignments I cannot find anywhere. It has hands on projects, but does not include the software to complete said projects.

    I had no prior knowledge of networking, programming, or any of the above, and at this point, I just want to make it through this class. I would have gladly dropped it as I can see I am in over my head, but I am on FAFSA funding and cannot drop below 12 credits without the risk of academic probation.

    Anyone willing to aid an IT idiot in any way would be much appreciated, I hope I came to the right place.

    Thanks for the consideration,
    Luminous

    You are welcome to post any of your specific problems.
    Just be as descriptive as possible and when you post code, don't forget to use the code tags.

    Please take a look at the sticky notes as well.

    Thanks! And I did check the stickies about posting. It's less about specific code, and more questions I just cannot figure out or find the answers to. I will post them and see if anyone knows.

    How many bits must be reallocated from host ID to network ID to create 16 subnets?

    What is the correct order of headers, from left to right, in a completed frame?
    a. Frame, TCP, IP
    b. UDP, frame, IP
    c. TCP, IP, frame
    d. Frame, IP, UDP

    Which of the following is a task performed by the Network access layer? (Select all that apply)
    a. Verifies that incoming frames have the correct destination MAC address
    b. Defines and verifies IP addresses
    c. Transmits and receives bit signals
    d. Resolves MAC addresses by using IP addresses
    e. Delivers packets efficiently

    What field of the IP header does the Tracert program use to get the IP address of routers in the path?
    a. Version
    b. TTL
    c. Checksum
    d. Protocol

    Which of the following is not found in a connectionless Transport-layer protocol? (choose all that apply)
    a. Three-way handshake
    b. Port numbers
    c. Checksum
    d. Acknowledgements

    Most of these can be found on Wikipedia. Specifically, you need to really understand HOW to find the answer to the first one if you're going to do anything with networking.

    Since I'm feeling charitable:
    1) 4
    2) (A) is the closest, but frames are far more complicated than this. Your book (Guide to Networking Essentials) covers it explicitly.
    3) For various communications protocols, A, and E, though you could make an argument for C
    4) D
    5) Nothing is found in a "connectionless" connection, since you don't have a connection you don't get any signal. Either this is a trick question or you need to use the book to define "connectionless."
    HEY! YOU! Read the New User Guide and Forum Rules

    Think we're being rude? Maybe you asked a bad question or you're a Help Vampire. Trying to argue intelligently? Please read this.

    Having worked in IT for a while now and learning most of my skills via self learning and "googling" you really need to learn to research the answers not having a go but after a uni degree, microsoft certification, most have my skills have been learnt googling. I have sat with senior software engineers and database developers and they get all funny when they dont know the answer off the top of their head. There is nothing wrong with " googling" but if you cant find what your looking for, post it here and il do my best to help you. Been in your position and its a pain, so anything i can help you with, i dont mind , beats the how do i add a printer or how di i reset my password nonsense!!!

    Just checked the date on your post after writing that duh!
