Answer:
The data-link layer
Explanation:
The physical layer and data-link layer are often confused a lot especially in terms of what they do in the TCP/IP 7 layer protocol. The physical layer as the name suggests represents the physical devices like the cables and the connectors that join or interconnect computers together. This layer is also responsible for sending the signals over to other connections of a network. The data-link, on the other hand, translates and interprets these sent binary signals so that network devices can communicate. This layer is responsible in adding mac addresses to data packets and encapsulating these packets into frames before being placed on the media for transmission. Since it resides in between the network layer and the physical layer, it connects the upper layers of the TCP/IP model to the physical layer.

Answer:
It can be repaired with disk utility / recovery algorithms
In UNIX it can be done by scanning
In FAT file scan the FAT looking for free entries
Explanation:
When the crash happens, it is not a problem for UNIX and FAT file system
It can be repaired with disk utility/recovery algorithms.
The recovery algorithm is a list of all blocks in all files and takes a compliment as new free file.
In UNIX scanning can be done at all I-nodes.
In FAT file problem cannot occur because there is no free list .If there was any problem than it would have to be done to recover it to scan the FAT looking for free entries.
