OSI Layer Six - Presentation Layer

the osi presentation layer translates data into an ppropiate transmission format. one function maintained at this layer is terminal emulation, which helps workstations that use different local data formats to communicate. an example of terminal emulation is the process a PC needs to communicate with mainframe computer. Other reformatting functions include data encryption and compression.

if you think of an example as the car highway, its the same as the signs you see on the road. it doesnt matter what language you speak, the X above a traffic lane means do not enter.

examples of presentation layer:
Terminal emulation
encryption
