Protocol layers may be defined in such a way that the communications within a layer is independent of the operation of the layer being being used. This is known as "peer-to-peer" communication and is an important goal of the OSI Reference Model.
Each layer provides a protocol to communicate with its peer. When a packet is transmitted by a layer, a header consisting of Protocol Control Information (PCI) is added to the data to be sent. In OSI terminology, the packet data (also known as the Payload) is called a Protocol Data Unit (PDU). The packet so-formed, called a Service Data Unit (SDU) is passed via a service access point to the layer below. This is sent using the service of the next lower protocol layer.

Two types of peer-to-peer networks exist that are:• Pure peer-to-peer Network:All Peers act as equals mean to say that there is no dedicated server, all behaves equally• Hybrid peer-to-peer Network:It act as the client¬server model because it has a central peer act as server that keeps information on peers and responds to requests for that information. Central server (peer) knows what resources are shared and what are free. They are also responsible for hosting management of available resources.

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.
OSI means Open System Interconnection. OSI is a standard model for networking given by ISO .

transport layer
OSI model has seven layers and each layer is assigned a specific task for data transmission process.

Open Systems Interconnection (OSI) model is the one which divides network communication process in to seven layers....
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
