L2 - Layer 2This is also referred to as the OSI (Open Systems Interconnection) Data Link Layer. It provides the means for synchronizing the bit stream flowing to and from the physical layer and for the detection of errors due to transmission problems e.g. noise and interference. An example of a Data Link protocol would be Ethernet operating on a LAN (Local Area Network).L3 - Layer 3This is also referred to as the OSI (Open Systems Interconnection) Network Layer. It provides the paths for the transfer of data between systems and across networks. The paths between systems may include switched services, and interconnections of multiple subnetworks on route. An example of a protocol operating at the network layer would be IP (Internet Protocol).----------------------------------------------------------------------------------------------------------How far you go in life depends on your being tender with the young, compassionate with the aged, sympathetic with the striving, and tolerant of the weak and strong. Because someday in your life you will have been all of these.
