A network engineer is analyzing how data packets are processed by a host computer when receiving a webpage request. The TCP/IP model handles this process across four distinct layers in a specific sequence from the physical transmission medium up to the web browser.
Complete the table below by matching each stage of the incoming packet's journey to its correct TCP/IP layer name.
Choose the layer names from the following list:
| Stage of Reception | Layer Name |
|---|---|
| Stage 1 (Bottom): Electrical or optical signals are received by the Network Interface Card (NIC) and hardware MAC addresses are verified. | [____________________] |
| Stage 2: The destination IP address of the packet is inspected to route it to the correct local host. | [____________________] |
| Stage 3: The data segments are reassembled in the correct order, checking for any lost packets. | [____________________] |
| Stage 4 (Top): The raw web data is parsed and displayed to the user via an internet browser. | [____________________] |
