You wouldn’t be able to communicate with other devices. Security over Wi-Fi would have to increase because of the unknown protocols by not allowing others to interact with your device unless they know the protocols.
Another example would be the OSI model. It makes it easier by actually showing the process.
Physical, Data, Link, Network, Transport, Session and presentation.
If the model is too general then you would not be able to understand it completely understand it. If it were too focused you still wouldn’t be able to understand.
1. It would not function the way it was intended. It needs all layers and components to operate the way it should. Shortcuts don’t create faster jobs with equal capabilities.
2. It was created so that there would be a single protocol for all vendors making it so all networks can work in synergy. It makes it so applications can talk over a network but is rarely used due to not being fully compatible with TCP/IP.
3. This is the standard way of communications via internet. It can also be used with intranet or extranet. It is the most commonly used protocol.

Physical layer is the bits, Data layer is the frames, Network is the packet, Transport is the segment, and Application Presentation and session are for data.
Transport- Segment Network- Packet Data Link- Frames.
A network has to read and decipher data so it knows what to show to the user.
Because it doesn’t have to present or interact with programs to direct traffic.
1. It allows common structures to be established at the data link layer and above without confining the structure of the bits themselves, so the bits can be transmitted through electrical or optical signals, or even wirelessly, and use the same frame structure; this allows data to cross networks that use different media....
