The OSI 7 layer model descibes the theoretical levels of networking on a computer Layer 1 Physical Layer - actual network cable and connectors
Layer 2 Data Link Layer - network address (MAC) and packet switching
Layer 3 Network Layer - internet Protocol (IP) - addressing and packet routing
Layer 4 Transport Layer - Transmission Control Protocol (TCP) - packet sequencing & error correction
Layer 5 Session Layer - Connection control for repeated send/receive (a session)
Layer 6 Presentation Layer - presenting information to application in correct format
LAyer 7 Application Layer - actual display/control of information, layout etc. for two computers to communicate -example chat program the following would occur user types into a chat program on computer A (7)
application accepts input and decides what to do with it (6)
a connection is requested to send to computer B (5)
the message is broken into pieces and encpsulated within a packet (which includes the address to send to and the address from which it came) Packets are given a sequence number(4)(3)
Packet sent across the network using the addressing information to determine where to go to(3)(2)(1) on Computer B the revers happens - packet is put back together - addressing information is removed and eventually displayed on the screen.

How the OSI model layer can effect a network's design and networking in general?
the OSI model prescribes the steps to be used to transfer data over a transmission medium from one networked device to another. A layered model defines each layer separately. [ As long as the interconnections between layers remain constant, protocol designers can specialize in one area (layer) without worrying about how any new implementations affect other layers. ]
How do the layers of the OSI model correlate to the layers of the OSI model?
