What is the function of the lower layers in the Open Systems Interconnection (OSI) model?
A) determining how a device connects physically using a transmission medium
B) determining how software applications will interface with the user
C) determining how any errors in data transmission will be identified and corrected
D) determining how the connection will be established and then broken off when finished

Question

Quizplus · Accepted Answer

The lower layers of the OSI model (physical, data link, and network) are responsible for determining how devices connect physically using a transmission medium, such as copper wire or fiber optic cables. They also define standards for data transmission and routing of information through networks.

Answer: C 
 Another important function of the lower layers is to ensure error-free data transmission. This is done by verifying that data packets are received properly and, if errors are detected, correcting them using error correction codes and retransmission.
