The Open Systems Interconnection model (OSI model) was a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a way of sub-dividing a communications system into smaller parts called layers. Similar communication functions are grouped into logical layers. A layer provides services to its upper layer while receiving services from the layer below. On each layer, an instance provides service to the instances at the layer above and requests service from the layer below.
For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.

* physical layer is the lowest layer of the OSI model and deals with "mechanical,electrical,fuctional and procedural means required for transmittion of the data according to the OSI defination,
application -top of osi model physical- bottom of osi model
Offcourse osi..... TCP/IP is an implementation of osi....
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
Repeaters operate at the physical layer of the OSI model.

The OSI Model stands for Open Systems Interconnection. The answer to the question which layer of the OSI model are layers capable of functioning is at all layers.
