The internet protocol suite is the conceptual model and set of communications protocols used on the internet and similar computer networksit is commonly known as tcp/ip because the foundational protocols in the suite are the transmission control protocol (tcp) and the internet protocol (ip) it is occasionally known as the department of defense (dod) model.

Everyone knows the divide and rule rule works always and it's productive tooeasy to understand networking the usual stated reason for this question is that the osi model is “too theoretical” and “doesn't apply to modern networking protocols like tcp/ip.
The tcp/ip model describes tcp/ip networks fortunately, very few network protocols are as poorly designed or as convoluted it was a good solution when cheap commodity hardware was imperative, but these days its inefficiencies are showing the po.

Explore log in create new account upload. Because both the osi and tcp/ip models are still used when describing modern day protocols, this article will take a look at them both, including their layers and how they can be related to each other. T hank goodness for computer networks if they'd never been invented, you wouldn't be reading this now (using the internet) and i wouldn't be writing it either (using a wireless home network to link up my computer equipment) there's no doubt that computer networking is extremely complex when you delve into it deeply, but the basic concept.
