In the sub topic : 4. Transport Layer, there is typing mistake in the last sentence:
The transport layer carries out flow control, sending data at a rate that matches the connection speed of the receiving device, and error control, checking if data was received incorrectly and if not, requesting it again.
where inplace of "incorrectly", it should have been "correctly"
