Hello all the patient people for helping me,

I have been looking at the breakdown of data going over a network. The breakdown of it now makes more sense, BUT professor messer talks about trucks moving boxes etc using the roads, and does a metaphor for the breakdown of this. So i now ‘get’ that IP contains TCP and UDP, and that contains HTTP etc. If these are protocols (am I right in saying that)?, then what would you consider ACTUAL data - the characters of a text, or frames of video, if all the packet breakdowns are protocols (which I define as sets of rules). Does that make sense? IP protocols, TCP protocols, UDP protocols, what is the actual info in a message called?
 
ok lets see if i can make this metaphor work for you....
The road is the cabling itself
the truck is the frame, inside the frame you have a box with labels that contain the src/dst MAC addresses and type, inside the box is the data itself. you can't send the data as is, it has to be "packaged" up and labelled correctly just like you would get when ordering from Amazon.
this metaphor is inefficient in that each truck only contains 1 box and if the data cannot be contained within the max size of a frame then it will send a fleet of trucks sufficient to carry all the required boxes that would make up the data with instructions on the label detailing to the destination application how to "unbox" everything in the right order to make sense.

How can you suggest a correct metaphor if you don’t understand what you’re trying to explain?

I wasn’t being facetious, OSI model explains all of this already and if you need explanation on top go watch a network chuck vid.

If you can’t put 2&2 together after that, give up as you’re out of your depth.

please explain to me where i have not understood what i'm trying to explain, the OSI model is that, a model if someone needs to find metaphors to get their head around the concepts thats fine
 
Truck metaphors make the thing more confusing for me than just seeing a packet payload drawn out with the headers from the various layers slapped in front of it.

Ok, Firstly what have you actually achieved with that post? You have ****** off AlphariusOmegan, and been rude to me! This is why forums get a bad name!

I think you actually mean “how can you suggest a correct metaphor if he doesn’t understand what you’re trying to explain” - what you have said actually doesn’t make sense. Metaphors actually enable the understanding of something - thats the whole point. If someone understood the concept, why use the metaphor?

I don’t really think you can compare this to infant school adding up.

You have actually used a metaphor yourself, after all that!

Whislt it’s not the same subject, I have a Psychology degree - with a lot of statistics, experimental designs, and tricky concepts, so I’m pretty sure I can do this.
I have thrown myself in, and spread myself too thinly over a few aspects of IT, without knowing the basics, and I’m not giving up just because of that.

2 plus 2 might seem simplistic, but what would happen if you didn’t know what a number was, or how to read them on the page!?

That’s a good metaphor. It’s amazing it can send all the packets via lots of different routes at once. I bought some adapters off Amazon which go into the wall sockets and the data can go through the power lines. Not sure how to work them yet, but I’ll figure it out. My cousin actually gave me a program called Cisco tracer. It’s pretty complicated, but looks a great way of playing with a network virtually, before, or whislt you build it. I have a switch, and s desktop PC with windows 11 pro on it. That has had Hyvi (spelt wrong) enabled, so I can teach myself (using tutorials), how to build virtual machines. I’m a long long way off from making it work - as I’ll have to take each bit and learn to configure it (after learning the theory). I guess one good thing is - I understand MAC address’ and ARP, and some of the IP parts.
