Dear All,
Now my account is playing ball, I can post this. I found a web page which was pretty good putting the OSI model into context. I have not been able to post on here for a bit because of some family stuff that's been happening.
They make the OSI model into how car moves along. So it needs alternator, drive shaft, battery, gearbox, bla bla bla, and when it has all it need it will move along. I thought this wass good. This is the link https://www.practicalnetworking.net/series/packet-traveling/osi-model/
Basically I think it mean each layer is required on the network, and once the frame/packet gets all the info and 'stuff' it needs, layer by layer, it will be able to move along the network.
I am now looking into the TCP/IP - cloudflare does pretty good description, saying it like a puzzle that gets broken into pieces at the senders end, and sent out into lots of different envelopes, and the IP controls the address for each. They all take different routes, and then are assembled at the other end, when they all are there. TCP ensures the connection and the moving of the pieces, and then put them back together in order at the other end.
There was a lot of talk on other sites about each later being encapsulated by another. Like those dolls you could get that unscrewed in the middle, and there was another smaller doll, and within that another smaller doll. They are all identical, and unscrew the same way, but encapsulate each other.
So not sure about this one yet, but working on it.
