Study Notes
The OSI Model
- The OSI model consists of 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application
Layer 1 - The Physical Layer
- Responsible for all physical properties of the network
Layer 4 - The Transport Layer
- Responsible for the actual mechanism of:
- End-to-end delivery
- Logical addressing (e.g. IPv4, IPv6, IPX, APPLE TALK)
- Routing (choosing the best path to the destination) (e.g. RIP, OSPF, IS-IS, EIGRP)
Layer 6 - The Presentation Layer
- Responsible for presenting data in the proper format
Layer 2 - The Data Link Layer
- Responsible for:
- Framing
- Error detection and correction
- Flow control
- Media access control
Other Layers
- Layer 7 - The Application Layer: responsible for protocols such as Email (SMTP, POP3), Web browsers (HTTP), FTP, and Telnet
- Layer 5 - The Session Layer: responsible for establishing, managing, and terminating connections between applications
- Layer 3 - The Network Layer: responsible for routing data between networks
Test your knowledge of the OSI model layers and their functions, from physical to application layer. Identify the responsibilities of each layer and understand how data is presented in the proper format at layer 6.
