OSI Model (Open Systems Interconnection Reference Model)
model for understanding and developing computer-to-computer communication developed in the 80s by ISO; divides networking functions among 7 layers
Responsible for the physics of the network (Signaling, Cabling, Connectors)
Data Link Layer
The second layer in the OSI model. bridges the networking media with the Network layer. Its primary function is to divide the data it receives from the Network layer into frames that can then be transmitted by the Physical layer.
Fragments frames to traverse to different networks. Also introduces Internet Protocol (IP)
Internet Protocol (IP)
The method of communication that allows information to be exchanged across the Internet and across varying platforms that may be accessing or sending information.
Responsible for moving "parcels" using TCP or UDP
Communication management between devices (Start, Stop, Restart)
Responsible for Character Encoding and Application Encryption. Often combined with the Application Layer
The only normally visible layer of the OSI Model
TCP (Transmission Control Protocol)
A communications protocol that uses packet switching to facilitate the transmission of messages; the protocol used with the Internet.
UDP (User Datagram Protocol)
A connectionless TCP/IP protocol for fast transport but no guarantee of delivery.
