Open System Interconnection (OSI)
a networking framework to implement protocols in seven layers
Physical Layer
The first layer of the model. It conveys the bit stream - electrical impulse, light or radio
signal — through the network at the electrical and mechanical level. It provides the hardware
means of sending and receiving data on a carrier, including defining cables, cards and
physical aspects.

Data Link Layer
The second layer. Data packets are encoded and decoded into bits. It furnishes transmission
protocol knowledge and management and handles errors in the physical layer, flow control
and frame synchronization. The data link layer is divided into two sub layers: The Media
Access Control (MAC) layer and the Logical Link Control (LLC) layer. The MAC sub layer
controls how a computer on the network gains access to the data and permission to transmit
it. The LLC layer controls frame synchronization, flow control and error checking.

Network Layer
The third layer. It provides switching and routing technologies, creating logical paths, known
as virtual circuits, for transmitting data from node to node. Routing and forwarding are
functions of this layer, as well as addressing, internetworking, error handling, congestion
control and packet sequencing.
Transport Layer
The fourth layer. It provides transparent transfer of data between end systems, or hosts, and
is responsible for end-to-end error recovery and flow control. It ensures complete data
transfer.
