3.1.1 You wouldn’t be able to communicate with other devices. You would have to go back to hardline phone and using mail service. No more on the go communications.
3.1.2 The OSI model. It actually shows the process.
3.1.3 Physical, Data, Link, Network, Transport, Session and Presentation.
3.1.4 If its too general the reader wont understand completely. And if its too focused or granular on details it will bore the reader.
3.2.1 Physical – Device Data Link – Physical address Network – Path determination Transport – End to end connections Session – internet Presentation – typing data Application – games, downloads ApplicationPresentationSession | Data | Transport | Segment | Network | Packet | Data Link | Frame | Physical | Bit |
3.2.2

3.2.3 First the receiving computer synchronizes with the digital signal by reading binary numbers. After synchronizing is complete and it gets the whole frame and passes it to the layer above it which is the Data Link layer. Second the Data Link layer will do a Cyclic Redundancy Check (CRC) on the frame. Checking for errors and then strip off any information or header which was put on by the remote systems Data Link layer and pass the rest to the Network layer. Third the Network layer checks the IP address and if it matches the Network layer header is stripped off from the packet and passed to the Transport layer. Fourth the Transport layer processes the segment and rebuilds the data stream and acknowledges to the transmitting computer that it received each piece. Then sends the data stream to the upper layer Application.
3.2.4 Because routers work primarily at Layer 3. They do not need the top Layers because the top Layers are the information being routed. The highest layer the router uses to where to forward traffic I
