What are the hardware devices that use these 2 OSI layers?

Question

I wanna know the hardware devices (router, switch...bluetooth anything) that uses the presentation layer & application layer of the OSI model.....

i know the presentation layer basically presents the data to the lower layers...and also encrypts the data....and that the application layer takes care of the application interface etc....

i can't seem to find an answer for this question any where......<_<....rather vexing really.....

Answer 1

The presentation layer, as you note, sits just below the application level, and is typically connected to the application layer. Although usually realised via software on a device, there are hardware elements - for example a cryptographic co-processor, or network encryption devices (e.g. SSL-Accelerators) that can be involved. If you were presenting secure data on a public network you'd probably use such devices, or have them from your provider (e.g. a secured lines).



The presentation layer is usually within the application server - so provided by the hosting software, rather than by any hardware per se. For example, the presentation layer could be HTTP, so the web server deals with this; or APPC, where the OS or app server offers an API into the service.

I am not sure..but I think its Random Access Memory, Hard Disk, Arithmetic Logic Unit, Memory Unit etc [for presentation layer] and Keyboard, mouse, monitor [for the application layer]... are the hardware devices that come into force when data is handled at the above mentioned OSI layers..

Your document can't be accessed. Going through Google Docs it simply says "Sorry, the page (or document) you have requested is not available.". Are you sure it's a public document? Since I can't see the project I can't help all that much, but the parts at the bottom seem simple enough. A quick google search of each of the protocols referenced there should give you a pretty good idea what they do, if you don't know them already (they're all very common/popular protocols).
