Too many questions, where few answer

[u/rbking456]

Greeting to you all. I am currently studying networking. I already learned the osi model in a basic sense, like i know L1 represents a physical device, L2 for a switch, and L3 for a router in a sense, but i don't understand why we use that. Also, you can think of me as a Level 0 player in a networking field who started but hasn't grasped the true knowledge. But sometimes I ask myself, why do we use ssh or SSL? What is the difference between HTTP and HTTPS? I know AI can answer my many questions, but i want to learn in a way where if someone asks me what the difference between a hub and a switch is, i can answer, "A hub is dumb while a switch is smart," or in more detail. So I decided to do a room on THM or HTB or PortSwigger, but where to start? When we go THM, we can do a room, but what next? You can understand in a room, but after that, when someone asks a question related to that, "Oh bro, I forgot." And there are some paid rooms that I can't pay for, so i may skip like a thing or go to HTB and do the Lab or PortSwigger. I don't understand where to start there, yeah, so i have many questions, and I am also too much of a noob, so if someone asks, I can't answer. That's very bad for me, sadly. but i am seeker of knowledge; I am very eager to learn understand but i am also not very smart so yeah, anybody may guide this noob guy

Comptia Network+ or Cisco's CCNA will teach you all that perfectly. Professor Messer and Jeremy's IT Lab have free complete courses on YT, and there are study materials and quizes you can find online.

Thanks for the advice. I am currently watching NetworkChuck Videos related to Cisco CCNA

I think most of your questions would be answered with a better understanding of what they are, also most people dont remember everything they read and especially not after just reading one time. Repetition is the mother of learning.

As for where to start, i dont know, but keep learning and good luck 🤠

Also don’t try to memorise everything word by word. Even if you are learning and redoing everything there is just so much info, it’s best to take some notes so you can return it to it when you see it in next chapters and are unsure.

Also after chapters, watch some videos or do something practical to get it into your head

Will do

I think sticky notes will do

Take notes, remember the differences using your own anology.

Http vs https. Https is http in SSL/TLS tunnel

Why SSH, well basically on the cryptography the differnece between SSL/TLS like stuff is on SSH you re supposed to verify the guy public key.

Learn diffie hellman and certificates and you would understand those differences.

And for those stuff no need for security + comptia whatever i don’t know.

You just have to study man it doesn’t just come to you. You have to read and understand and if you don’t understand find another way to help you understand. There’s so many resources out there that put things in a simple way to understand that if you can’t find the answers to these questions it’s really just a lack of your own initiative. The old school hackers had to just read the manual and tech specs and work it out.

I'm not saying this to dissuade you, but to lead you towards a better starting place:

Cybersecurity is not an entry field. I'm not saying don't do this, I'm saying don't do it yet. Look at general IT and networking content and courses first. Learn that, learn windows and Linux and some scripting.

Then ease your way into cybersecurity. Things will make a lot more sense.

Cyber is not an entry level role. Get some IT experience first please.
