If low speed CAN has an open circuit in one of its wires, what will happen?
The control modules will still function normally, but have faults for single wire mode
The control modules will only partially function, but have faults for single wire mode

What protocol(s) is used at the Network layer?
Transmission Control Protocol (TCP)
Both options are protocols used at the Network layer
Internet Protocol (IP)
What information is found in a TCP header?
Destination port

Both options are found in a TCP header
What function is performed at the Data Link layer?
Move the data from device to device across the network
Sequence the data for reassembly at the destination
Packets are addressed so they can be routed through the network to the destination
Why were the Data Link & Physical layers divided into two separate layers in the current TCP/IP model?
Because the number of protocols grew too large for the link layer to handle it by itself
Because networks use different types of transmission media (ethernet wire, fiber optic cable, and radio signals) to transmit bits
Because the original TCP/IP model was too complicated for many typical uses
What is done with the data at the physical layer?
The physical layer header is added to the frame to prepare it for transmission
Both occur at the physical layer
The data is converted into its intended transmission media (electrical, light, radio wave) and sent down its transmission path
