What is the OSI Model Protocol? |
The Open Systems Interconnection Model Protocol is made up of 7 different software and hardware layers. Each of the 7 layers add a bit of code to the data which is then stripped away in reverse order when it reaches the destination. |
|
|
Application Layer |
-First layer -Allows applications to access network services -Represents the layer at which the applications can access the network -Provides services that directly support network applications |
|
|
Presentation Layer |
-Second layer -Translated application data, via the transmitting side, into a format that can be sent over the network -Translates the application data, via the receiving side, back into its original format -Is the level at which the re director operates -Manages security by providing functions including data encryption and compression |
|
|
Session Layer |
-Third layer -Creates a session between two computers to let communication occur -Determines how long workstations transmit and when transmission occurs |
|
|
Transport Layer |
- Fourth layer -Ensures that data is error free -Ensures data is sent in the proper order |
|
|
Network Layer |
-Fifth Layer -Handles network congestion -Handles message addressing -Routes packet from source to destination |
|
|
Data Link Layer |
-Sixth Layer -Establishes a logical link -Relies on acknowledgement from other computer -Re transmits any frames that are not acknowledged |
|
|
Physical Layer |
-Seventh and final layer -Defines cabling type -Defines pin configurations -Deals with transmission speeds and data encoding. |
