Which layer of OSI reference model provides inter network connectivity.
Which layer of OSI reference model provides inter network connectivity.
The correct option is B Network
Network layer of OSI reference model provides inter
network connectivity.
The network layer is the third level of the Open
Systems Interconnection Model (OSI Model) and the layer that provides data
routing paths for network communication. Data is transferred in the form of
packets via logical network paths in an ordered format controlled by the
network layer.
The International Standards Organization (ISO)
developed the Open Systems Interconnection (OSI) model. It divides network
communication into seven layers. Layers 1-4 are considered the lower layers,
and mostly concern themselves with moving data around. Layers 5-7, the upper
layers, contain application-level data.
Functions of the network layer. The primary
function of the network layer is to permit different networks to be
interconnected. It does this by forwarding packets to network routers, which
rely on algorithms to determine the best paths for the data to travel. These
paths are known as virtual circuits.
Network protocols also define rules for
communicating in a particular networking environment such as Ethernet or Token
Ring. IP - This is short for Internet Protocol which works at the OSI network
layer and is a routed protocol for forwarding layer 3 packets. IPX - NetWare's
protocol for packet forwarding and routing.
