What are the layers of the OSI Reference Model?
- Application
- Presentation
- Session
- Transport
- Network
- Data-Link
- Physical
Physical Layer
- Governs the layout of cables and devices such as repeaters and hubs.
- electrical characteristics of signals
- fiber optic
- wireless
- NIC cards
Data-Link Layer
- Lowest layer meaning is assigned
- Packet size
- Packet addressing- MAC address
- Basic error protection and encription
- CSMA/CD and Token passing
- Bridges and switcheds
Network Layer
- Routing between different networks
- IP and IPX
- Packet sequencing
- error detection
- congestion control
Transport Layer
- Ensure packets are transported reliably and without errors
- Connection Establishment
- Receipt acknowlegement
- Packet division
- Packet reassembly
- TCP and UDP
- Netstat command to view connections
Session Layer
- Session = Conversation = Multiple Connections
- Simplex: Data flows in one direction
- Half-Duplex: Data flows in both directions, but only in one direction at a time
- Full-Duplex: Data flows in both directions at the same time
Presentation Layer
- Converts data so that systems that use different data formats can exchange data
- Compression
- Encription
- ASCII: American Standard Code for Information Interchange
- EBCDIC: Extended Binary Coded Decimal InterChange
Application Layer
- Programming interfaces applications use to request network services
- DNS
- FTP
- SMTP
- SMB
- NFS (Network File System)
- Telnet (Termnial Emulation)
