A server receives an incoming database query packet via a fiber-optic connection. The TCP/IP model processes this incoming data by passing it up through its four layers in sequence, from the physical transmission media up to the database software.
Complete the table below to show the correct order in which the four TCP/IP layers process this incoming data.
Place the layers in order from 1 to 4, where 1 is the first layer to process the incoming signals from the physical medium, and 4 is the final layer that presents the payload to the database application.
Select from the following list of layers:
| Sequence of Processing (1 = First, 4 = Last) | Layer Name |
|---|---|
| 1 | [____________] |
| 2 | [____________] |
| 3 | [____________] |
| 4 | [____________] |
