End-to-end connectivity is provided from host-to-host in:

A) Network layer B) Session layer C) Data link layer D) Transport layer E) None of the above

Discuss

Answer & Solution

Answer: Option D

Solution:

End-to-end connectivity is provided from host-to-host in the Transport layer.

The Transport layer is responsible for ensuring reliable data transmission between the source and destination hosts. It establishes a logical connection between the sender and receiver, manages data flow control, error detection and correction, and sequencing of data packets. By providing end-to-end connectivity, the Transport layer ensures that data can travel from the source host to the destination host reliably and efficiently.

Therefore, the correct answer is Option D: Transport layer.
