The Modification of the MAC address is done by the Routers. The Source and Destination MAC address would keep on modifying as the Frame moves in the network. The source MAC address is resolved by using the ARP(Address Resolution Protocol). Here is the Data link layer the header is added, the header consists of the fields. Frames: The Packets received from the Network Layer further processed to form the Frames. This fragmentation is done at the Routers.ģ. This layer is also responsible for fragmentation if required when MTU of the network is less. Thus the IP header along with the body (which contains the segment from the Transport layer) makes the IP Packet or popularly only Packet. The IP headers are continuously modified as the packets in the networks because TTL keeps on changing with each hop. To the IP body, the IP header is added which has the fields as mentioned above. Now let’s understand the concept, the IP body contains the Segment received from the Transport Layer without any of the modifications. The IP header has many fields namely:- 1. The IP packet has a header of varying sizes from 20B to 60B. Packets: The segments received from the Transport layer are further processed to form the Packets. And this TCP is also responsible for acknowledgements when segments are delivered.Ģ. The TCP helps break the data(given by application layer) into MSS(Maximum Segment Size) that the given network can handle so that further fragmentation doesn’t occur in the routers. The Application layer can give any amount of data to the underlying layers, but it is not possible to send all the data given by the application layer to send directly. This is the basic meaning of different terms used in Computer Networks. The PDU of the Data-Link Layer is called Frames.The PDU of Network Layer is called as a Packet.The PDU of Transport Layer is called as a Segment.The PDU has a different meaning in different layers still we can use it as a common term. Thus PDU gives an abstract idea of the data packets. The term PDU is used to refer to the packets in different layers of the OSI model. Before starting it is better to get acquainted with a term called Protocol Data Unit (PDU). In this article, we learn what’s the exact difference between the term which is often misused in Computer Networks and a lot of confusion prevails on the usage of these terms.
