Table of contents [ hide ] The Internet Model includes 4 layers and 7 layers, usually, we use 7 layers for education and communication. Physical Specifies how data is processed into bits and physically transferred over cables. Media type. Connector type. Signal strength. Coding Mechanism. Data link Provides the link for how data packaged into frames is communicated through hardware to transport across a medium. Medium Access. Physical Address. Frame. Ethernet_frame: Network The network layer provides the functional and procedural means of transferring packets from one node to another connected in "different networks" Defines the format of the logical address. Provide routing and best path. IPV4 packet Icmp ICMP messages are typically used for diagnostic or control purposes or generated in response to errors in IP operations (as specified in RFC 1122).
