Options
- ANetwork
- BData link
- CTransport
- DSession
Explanation
The transport layer is the OSI model layer that will discard a segment with a bad checksum in the UDP header. The transport layer is responsible for providing end-to-end data transmission and reliability between the source and destination hosts. The transport layer uses protocols such as TCP (transmission control protocol) or UDP (user datagram protocol) to segment, encapsulate, and deliver the data. The transport layer also performs error detection and correction using checksums, which are values calculated from the data and added to the header of each segment. The checksums are verified at the destination host to ensure the integrity of the data. If the checksum in the UDP header does not match the expected value, the transport layer will discard the segment as corrupted.
