Define Function of OSI Layers, Basic Computer Science
OSI Layers: Open Systems Interconnection model is a reference model developed by International Organization for Standardization in 1984, as a conceptual structure of principles for communication in the network across different applications by different vendors
Layer 7:Application Layer
Application layer interface to user processes for communication and data transfer in network. Provides consistent services such as virtual terminal, file and job transfer and operations
Layer 6:Presentation Layer
Masks the differences of data formats between different systems Specifies architecture-independent data transfer format Encodes and decodes data; Encrypts and decrypts data; Compresses and decompresses data
Layer 5:Session Layer
Important function of session layer are :
Dialog controller - Session layer is the dialog controller. it establishes, maintain and synchronizes between communicating system, token management- its also provide token management services

Layer 3:Network Layer
Determines how data are transferred between network devices Routes packets according to unique network device addresses Provides flow and congestion control to prevent network resource depletion
Layer 2:Data Link Layer
