Open System Interconnection (OSI) Reference Model

- The OSI has 7 layers that describe the tasks that must be performed to transfer information on the network.

- When data is being transferred over a network, it must pass through each layer of the OSI model.

- As the data passes through each layer, information is added to that data. At the destination, the additional data is removed.

- Layers 4 through 7 occur at the end node, Layer 1 through Layer 3 are the most important to telecommunications network.
