What is the maximum size of data that the Network layer can forward to the Data link layer on the TCP layer, including header data?
- Any size
- 65,535 bytes
- 65,515 bytes
- 1500 bytes
This question has been asked before but given answers don’t explain reasoning properly.
Link to similar question : https://gateoverflow.in/152223/%23tcp-ip
If data link layer can have maximum 1500 Bytes data in a frame, then shouldn’t fragmentation happen at network layer ? And therefore maximum data size that network layer can forward to data link layer should be 1500 Bytes.
Please explain how network layer can send 65,535 Bytes data when data link layer cannot have more than 1500 Bytes and fragmentation cannot happen at data link layer.
