Computer Networking Question(s)
Im in a computer networking class and need some explanations of things if anyone knows alot about networking. Okay, in the OSI model, I get the 7 layers....and each layer has certain functions right? well why do some layers repeat those tasks...like flow control, encryption. do packets turn into frames..that turn into bits???
whats packet sniffing? is there frame sniffing? bit sniffing??? SPDU sniffing!?!? Why are the first 3 layers apart of the 'subnet' and not the other layers. Whats the freaking purpose of the session and presentation layer?! they suck. Wheres the "medium access layer" in the OSI model? data-link?? and whats the big deal about medium access...its boring. Whats the point of token ring? it seems slow and pointless. I just need a detailed explanation of this stuff from a computer expert. I understand programming, but networking seems like another system. |
Sorry guy I don't know how to help you...or do I? by japan

The Tolkein ring was meant to bind all the nine kings together under the rule of Sauron.
It seems slow and pointless because it was written in the '30s. |

I could reply to each of the questions, but since your a programmer. I would reccommend reading a Network + book. They are cheap and will answer any of your questions.
If the above questions are for specific reasons, let me know I can add further detail. The range of questions above could take a bit to answer if the fundamentals of networking is not understood. |

your right, i do need to read more books. Im just too lazy. Ill get on that. finals are coming up and I think this class might be the only one that isnt an A for me. All I have to say is that I underestimated those networking guys, that stuff is hard!

@ Cyrius. Ive read that part of the OSI model. I just dont get how each layer works together to form a message. Cuz we just learned that Bridges are for layer 2 data, and routers are for layer 3 data....so each layer is sent seperatly?
