OSI model has seven layers and each layer is assigned a specific task for data transmission process.
UDP or User Datagram Protocol works on the Transport Layer (layer 4) in the OSI model.
PGP works at the Layer 6 - Presentation level.
it works in layer 2
A firewall generally works at layer 3 and 4 of the OSI model. Layer 3 is the Network Layer where IP works and Layer 4 is the Transport Layer, where TCP and UDP function. Many firewalls today have advanced up the OSI layers and can even understand Layer 7 - the Application Layer.

It depends on what kind of model it is, but in the model for computer 321O, it is on the layer between trhe keyboard and the behind screen, and there is a button with the osi code and there says everything.
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm
HTML is read by a browser and a browser works at the Application Layer.
No. Hub works only on first layer. On second layer only swithc/bridge works on second layer of OSI model.
Transciever works on the Physical Layer(Layer 1) of the OSI because its basically a repeater or a MAU\ Multi Station Access Unit
