Application Layer (7)
Where communications begin and end. Type of communications; ex: email Does not include standard application, only web and network applications.
Presentation Layer (6)
Encryption, compression, coding, formatting, file extensions. (Syntax Conversion) Translates application protocol to network protocol and network into application. Might compress and decompress as well as encrypt data.
Session Layer (5)
Transmission control and order. Sets up and tears down the call. Makes connection between applications to allow large amounts of data to be transferred, used in games a lot. Recovers connection and organizes received packets.
Transport Layer (4)
Ensures source to destination delivery/ makes sure it gets there. Data segments and flow control. Communication for the Session Layer. (Connection Oriented)
Network Layer (3)
Routes data packets using IP addresses. Uses best path selection.
Data Link Layer (2)
Transmits frames using MAC addresses. (Media Access)
Physical Layer (1)
Converts bits to electronic/ optical pulses. Transmits to destination device.
Protocol
A defined method for communicating between systems. (common computer language)
