Just passed Net+. Thanks Messer! PS. Learn the OSI Model, guys. It's a slog right now but it's EXTREMELY Important!!

Congrats! Same here, passed my A+ twice 901-902 and 1001-1002 with his course notes, on to Net+ my 2nd run, didnt pass the first time n10-007 shooting for N10-008.😀

How’d you do on the network test?

@well_intended_devil Год назад

I just learned more from this lesson than I have in two months taking a network class at community college. Thank you SO much for going through all this effort to provide FREE above-college-quality instruction. You're a blessing to humanity Professor Messor. Gods be with you.

I passed my A+ Sept 1st. I spent the last month teaching myself data+ and SQL. I learned some things but realized it was a bit to chew 🤦🏾‍♂️ so now I'm back at square 3 😄. I should have just went straight to Net+! 😄. How's it going for you?

@mohammadrezakalantari6830 5 месяцев назад

hi , have you learned also from the CompTIA book? I mean, there is so many subjects that were not taught in the professor course. so I don't no whether they are also important. I would be delighted if you could help me with this to know.

Your videos are highly inestimable. As I ply these paths to cybersecurity, must always wish you more years in good health and strength so you could keep creating these useful videos for us all. Thanks Prof.

@ztreddedb2949 Год назад

This video was simply amazing. I don't think I've ever seen anyone explain the OSI model backwards, starting with layer 7. Now it finally makes sense because this is how we all use computers, people start with the application layer, this is how OSI model should be taught - truly genius!!!!!!!!!

@wh0c4r3s5 2 года назад

Excellent video breaking down the different layers of the OSI model. Another mnemonic I learned about the OSI model that helps break down the data and at what stage it is in= bacon frying produces salivation.... Bacon=BITS= layer 1 (physical) Frying=FRAMES=layer 2 (data link) Produces=PACKETS=layer 3 (network) Salivation=SEGMENT=layer 4 (transport)

@barebears289 2 года назад

Just want to say that I'm very grateful that I've gotten this far in my studies in IT, and that if it weren't for these videos I would have never passed A+ 1101/1102. I appreciate how you've broken down the OSI model.

@TheOfficialJLB 2 года назад

I've always liked to visualize how data flows through a network and use "the physical data network transports the session presentation application."

@Us3r_404 2 года назад

how much different are the n10-007 notes from n10-008. if i have the 007 notes already and have my exam scheduled soon would it benefit me to purhcase the 008 notes? like is it mostly the same information written in a different way?

@professormesser 2 года назад

About 40% of the N10-008 exam objectives are new from the N10-007, so there's quite a bit that has been updated. I would recommend only studying from materials that match the version of the exam that you're planning to take.

Hi 👋 I got a question I am a CCNA certified but within 3 months my certificate will be expired. I want to know if I pass Network+ and get the certificate can that update my CCNA expiration date or no? Or if not what will be the the alternatives to avoid expiration of my certificate. Also I want to know what will be the impact if my certificate expires!!!! Please answer if you know the answers

@scottmagyar6572 Год назад

To my knowledge, they are not related, so no, passing the Network+ Cert will not update any CCNA expirations you might have.
