  1. What are the layers of the OSI Reference Model?
    • Application
    • Presentation
    • Session
    • Transport
    • Network
    • Data-Link
    • Physical
  2. Physical Layer
    • Governs the layout of cables and devices such as repeaters and hubs.
    • electrical characteristics of signals
    • fiber optic
    • wireless
    • NIC cards
  3. 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
  4. Network Layer
    • Routing between different networks
    • IP and IPX
    • Packet sequencing
    • error detection
    • congestion control
  5. 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
  6. 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
  7. 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
  8. Application Layer
    • Programming interfaces applications use to request network services
    • DNS
    • FTP
    • SMTP
    • SMB
    • NFS (Network File System)
    • Telnet (Termnial Emulation)
  9. 10BaseT
    • Standard Ethernet
    • Cable Type: CAT 3 UTP
    • Speed: 10 Mbps
    • Max Seg Length: 100 meters
  10. 100BaseTX
    • Fast Ethernet
    • Cable Type: CAT 5 UTP
    • Speed: 100 Mbps
    • Max Seg Length: 100 meters
  11. 100BaseFX
    • Fast Ethernet
    • Cable Type: 62.5/125 multimode fiber optic
    • Speed: 100 Mbps
    • Max Seg Length: 1. Half duplex = 412 meters; 2. Full duplex = 2,000 meters
  12. 1000BaseLX (Single-mode)
    • Gigabit Ethernet

  13. 1000BaseLX (Multimode)
    • Gigabit Ethernet
    • Cable Type: 50/125 or 62.5/125 multimode fiber optic
    • Speed: 1000 Mbps
    • Max Seg Length: 550 meters
  14. 1000BaseSX (400 MHz)
    • Gigabit Ethernet
    • Cable Type: 50/125 multimode fiber optic (400 Mhz)
    • Speed: 1000 Mbps
    • Max Seg Length: 500 meters
  15. 1000BaseSX (160MHz)
    • Gigabit Ethernet
    • Cable Type: 62.5/125 multimode (160 MHz)
    • Speed: 1000 Mbps
    • Max Seg Length: 220 meters
  16. 1000BaseT
