Why are protocols divided into layers? - Short-Fact And it is considered as a standard model in computer networking. Slower in execution : If a layer wants to interact with another layer, it sends a request that has to travel through all the layers present in between the two interacting layers. An example of this is the IPv4 header checksum which is now being discarded in IPv6 - layers 2 and 4 can instead provide reliability as desired - and for data, not just a header. Additional air gaps between various layers increase the insulation. - Disadvantages of layered operating systems are: It is difficult to exactly assign of functionalities to the correct and appropriate layer.
