Transport (layer 4) |
Layer is responsible for reliable network communication between end nodes (TCP, UDP) |
|
Session (layer 5) |
Defines how to establish and terminate a session between the two systems. (SSL, NetBIOS) |
|
Presentation (layer 6) |
Layer ensures that information sent by the application layer of one system will be readable by the application layer of another (MIME) |
|
Application (layer 7) |
Enables network applications to communicate with other network applications. (HTTP) |
|
Ethernet |
Connecting a number of computer systems to form a local area network |
|

Serves as a central point to which all of the hosts in a network connect to. OSI Layer 1, sometimes called multiport repeater. |
|
OSI |
Open systems interconnection Has 7 layers which are Physical (please), Data link (do), Network (not), Transport (throw), Session (sausage), Presentation (pizza), Application (away) |
|
MAC |
Media access control |
|
Switch |
Is used to connect multiple hosts together. OSI layer 2, can inspect received traffic and make forwarding decisions |
