OSI Standard
Layers
Transport Layer 4
Segments and resembles data from upper layers and unites the into the same data stream. provides flow control for data-loss prevention as well as reliable and unreliable transport methods
Network Layer 3
Provides Logical Network Addressing and path determination/routing services. responsible for packet delivery, fragmentation, and sequencing. this is the layer where internet protocol resides.
Session Layer 5
Coordinates, establishes, manages and tear down sessions between applications on either side of the connection. Maintains seprate sessions for the diffrent applications data streams.
Data Link Layer 2
LLC includes the logical link control (LLC) sublayer which provides error detection and control.
Mac delvers frames using unique hardware addressing VIA the media access control (MAC) Sublayer.
Presentaion Layer 6
Provides translation to. From the application layer. Preforms data encryption, decryption compression and decompression. Associated with file formats such as JPEG, Mpeg ext.
Physical Layer 1
Turns raw bits into electrical signaling and defines physical network media such as copper cabling, fiber options, and wireless transmission standards. concerned with bit rates and transmission modes
Application Layer 7
Application services for end user processes such as file transfers, email, remote terminal access, domain resolution, web transfer, network management, protocols such as 'FTP & Telnet
