Which OSI(Open Systems Interconnection model) layer is related to the function of the IP protocol suite? Network Which OSI(Open Systems Interconnection model) layer is responsible for organizing how bits are passed over the physical layer between devices within the same collision domain?

CAT 6a Which Internet access technology uses ordinary telephone wires for data transmission? DSL(Digital Subscriber Line) Which device is used to organize network cables as they run between switches and other network devices? Patch panel Which network device is used to connect two or more network segments by performing OSI layer 3 functions like packet-forwarding? Router Which network device is used to convert between digital information from a LAN and analog signals for transmission over a standard telephone wire?
