Hi everyone,

Im little confused about the naming of the layer 4 and layer 3 encapsulated packets cus ive seen conflicting info from different sources/different tests online!

Some say datagram is at layer 3 as in IP datagram.
Soem say datagrams are at layer 4 as in Datagram segments.

Can someone clarify this pls?!

Thanks!

    Layer 4 - TCP(Segments) or UDP(Datagrams)
    Layer 3 - IP(Packets)
    Layer 2 - Ethernet(Frames), ATM(Cells) etc.....
    Layer 1 - Bits
