Transport Layer Question

up2thetime

Hey everyone,

Simple question on transport layer...

If PC1 has a large file to sent to PC2 (say 100MB), is the file broken up into segments then handed down to the Transport Layer?

Or is the whole 100MB handed down to the transport layer and broken up from there?

I understand the transport layer, network layer, data link layer all add to the encapsulation process, I am just not quite sure on where file is actually split up. I would assume the transport layer breaks the file up as it must perform sequencing as well.

Is that correct?

Thank you.

The transport layer will break this up typically 512 - 18K bytes, below is a good quick overview of the OSI model.
