Question
.LP
A hard drive works using spinning platters, read heads, and magnetic tracks and sectors, which has the data laid out in an organised pattern. The hard drives spin the platters and move the read write heads to read and write data to and from the disk.

The Application layer of the TCP/IP stack is the web server itself, this will take the incoming files and move them onto the drives.

The Transport layer of the stack, will handle the data being broken up into packets, that can be sent over the network. This will also apply the checksum and other such security and verification steps.

The Network layer will apply the sender and return IP address onto the packet.

The Link layer is the physical cables, and other connectivity methods between the 2 machines.
