  • 2. Agenda• Network Definition• Types of Network• Network Terms• OSI Model• Network Components• Enterprise Network Architecture
  • 3. Network Definition
  • 4. What is Network?• A network, is a collection of computers and devices interconnected to facilitate communications among users and allows users to share resources.
  • 5. Types of Network
  • 6. Local Area Network• Connects computers and devices in a limited geographical area
  • 7. Wide Area Network• LANs that spans over a broad area (regional, global)
  • 8. Virtual Private Network• Connects multiple LANs securely over WAN
  • 9. Network Terms
  • 10. Common Network Terms (1)• MAC Address - Physical Address of a Device ▫ E.g. “ 08:00:69:02:01:FC ”• IP Address – Logical Address of a Device ▫ e.g. “ ”• Protocol – Set of rules that govern a communication ▫ e.g. TCP, UDP• Subnet ▫ Block of IP Addresses
  • 11. Common Network Terms (2)• Fast Ethernet ▫ 10/100 Mbits/sec• Gigabit Ethernet ▫ 10/100/1000 Mbits/sec• Power Over Ethernet ▫ Feature that supports a device to pass power along with data on Ethernet Cabling• VLAN ▫ a VLAN is a collection of nodes that are virtually grouped together.
  • 12. Open Systems Interconnection(OSI model)
  • 13. OSI Model• Open Systems Interconnection ( OSI ) is a standard reference model for communication between two end users in a network. The model is used in developing products and understanding networks.
  • 14. OSI model - Layers Application • Network Process to Application (Email, Internet Explorer) Presentation • Data Format, Ensure Data is readable (JPEG, GIF) Session • Establish, Maintain & Disconnect (Host to Host Chat Session) Transport • End to End Connection, Reliability (TCP, UDP) Network • Network Address, Best Path (IP, Router) Data Link • Access to Media (MAC, Switches, Hub) Physical • Binary Transmission (wires, voltages)
  • 15. Network Components
  • 16. Passive Components Application • UTP Cable • Patch Panel Presentation Session Transport • SFP Module • Fibre Cable Network Data Link Physical
  • 17. Network Switch Application ▫ Devices that links nodes in a LAN ▫ Layer 2 Device Presentation ▫ Works on MAC Address Session Transport Network Data Link Cisco 2960 Switch Physical
  • 18. Router Application ▫ Responsible for Routing, Path selection Presentation ▫ Layer 3 Device Session ▫ Works on IP Address Transport Network Cisco 1941 Router Data Link Linksys Router Physical
  • 19. Multi-Layer Switch Application ▫ Device that switches on OSI layer 2 like an ordinary network switch and provides Presentation extra functions on higher OSI layers. ▫ Inter –VLAN Routing Session Transport Network Data Link Cisco 3560, Cisco 4500 & Cisco 6500 Physical
  • 20. Wireless Access Point Application ▫ allows devices to connect to a wired network with out the need of physical Presentation cable Session Transport Network Data Link Cisco Aironet 1140, 1260, 1500 Series Physical
  • 21. Firewall Application ▫ Security Device ▫ Offers protection between Presentation Zones Session ▫ Todays Firewall offers Network to Application Level Protection Transport Network FortiGate UTM Data Link Physical Cisco ASA
