In this video, we’ll detail the important protocols in the link, internet, and transport layers of the IP suite.

    Great video!
    I wonder if its wrong to say that ARP is a network layer protocol too?
    Cause ARP is using both IP adresses(Network layer) and MAC adresses (Link layer). Right?

    • Rickard –

      Although ARP operates at Layer 2, it’s completely appropriate to consider the Layer 3 aspects of the protocol.

      The OSI model isn’t a static set of rules, and there are plenty of places where protocols and technologies can span many different OSI layers.

    Dear Professor James,
    I am writing to express my sincere appreciation to you for all the efforts you did put to present a free video comptia A+ online. Let me tell you a little bit about myself, i am a practising civil engineer for 10yrs before recession struck last year, i was made redundant and life become so tough, i mean tough, i could not secure any construction job anymore. so while i was looking for an alternative means to earn money, a friend introduced A+ certification to me, so i went online bought a book from amazon by Mike Meyer and i started to study. While in the library one day, i met another guy studying for A+ also he gave me your website and my study becomes easier and also introduce me to a cisco academy. I started studying in Deceember 2008 and today i had passed both 601-750 and 602-900. i am very grateful for your help and i pray to GOD to reward you greatly. I also want to know when you will upload the video for N+, that is my next step, please do it quick and thank you.

    I have finished A+ now and now I am working on Network+. The review section at the back has changed for the better. In nearly all A+ videos I skipped the review. That was a major improvement of time.

    Thanks again,
    M. Jared Carson

    I lost my job with the recession, I was in manufacturing and had computer experiance so when i decided to take a new carrer path I looked into getting my certs. I bought the A+ and NET+ books then found your website and I have to say these training videos are the best, I passed the A+ 220-601 and 602 after reading the first 3 chapterts of the book then watching all of your videos. I’m starting the NET+ today and am going to watch the videos first then go to the book. when i’m finished with the NET+ i’m going to start the CCNA.

    I passed my A+ recently with a lot of help from Professor Messer. After watching the first segment of the Network+ video it is apparent that nothing will be missing throughout his lessons. Thanks Professor Messer.

  9. Dirk says:

    I am stunned.

    This vastly surpasses -all- the paid training video’s I have previewed so far.

    It is very clear what you are talking about, you are to the point and have a pace that perfectly fits my personal requirements.

    Thank you very much Professor Messer.

    Thank you so much. I passed my Network+ exam today and without your videos I don’t think it would have happened. You explained objectives that I just couldn’t get from the QuickCert videos. Thank you again for your marvelous work.
