OSI Reference Model - Transport Layer
 
Transport services allow users to segment and reassemble several upper-layer applications onto the same transport layer data stream.It also establishes the end-to-end connection, from your host to another host. As the transport layer sends its segments, it can also ensure data integrity. Essentially the transport layer opens up the connection from your system through a network and then through a wide area cloud to the receiving system at the other end.

OSI Reference Model : Network Layer
 
The network layer is where the actual delivery of the transport data units takes
place. The network layer provides the delivery and addressing services needed to
move the transport data units from host to host. This is accomplished by sequencing the data into data packets and adding a delivery information header with the source and destination addresses and any additional sequencing information.

OSI Reference Model Physical & Data Link Layers
 
The physical layer deals with specifications of the medium used to move bit data from point to point. All physical, electrical, and mechanical aspects of the transmission media are addressed at Layer 1. Layer 1 and Layer 2 are also
commonly looked at together because the physical layer standards are usually taken for granted.

Switching Technologies
 
With the advent of faster computer networks and a far more stable infrastructure has come the need for a quicker way to “switch” this information around. Two of the best known methods for doing so are ATM and Frame Relay. Within the confines of this article we will discuss just what they are and where they fit in.

The OSI Reference Model
 
The OSI Reference Model is based on a proposal developed by the International Standards Organization (ISO). The model is called ISO OSI (Open systems Interconnection) Reference Model because it deals with connecting open systems - that is, systems that are open for communication with other systems.
