Segment :
– Actual Data part + With Checksum
– Segment is part of file which is send from from session layer
– if file is in huge size , it will divided into small parts and send them to receiver over the internet in Transport Layer, each part is called segment
– Each Segment has checksum(which has information of total parts ) to check the file receive errors(one segment or more segments are missing like) at receivers end .
Packet :
Sender IP + Receivers IP + [Segment : Data file part + checksum]
– Packet is part of entire data file , which is sending over network
– Packet is capsule of IP’s and Segments
– Operational at Network Layer (TCP/IP or OSI Mode)
– It consists of Sender IP + Receivers IP + Segment
–
Frame :
– Senders MAC + Receivers MAC + {Sender IP + Receivers IP + [Segment : Data file part + checksum] } + Tail (Error check – binary information store)
– It is like a container or capsule used to send data over internet – it is also a piece of entire data
– Layer : Data Link layer
– Helpful handle the errors in receiving the files
