    1. NETWORK CABLING Chapter 2

    2. Chapter 2: NETWORK CABLING 2 TOPOLOGIES There are three main local area network (LAN) topologies: Bus Star Ring Other network topologies include: Mesh Wireless

    3. Chapter 2: NETWORK CABLING 3 BUS TOPOLOGY The bus topology supports thick and thin coaxial segments. Segments are connected by repeaters. The bus topology uses the baseband signaling method. Signals are broadcast in both directions simultaneously. Both ends of each segment require termination to avoid reflection. End systems connect to the segment in a linear manner.

    4. Chapter 2: NETWORK CABLING 4 THICK AND THIN COAXIAL BUS

    5. Chapter 2: NETWORK CABLING 5 STAR TOPOLOGY The star topology can use coaxial, twisted pair, or fiber optic cable. A central device (hub) connects hubs and nodes to the network. Each node connects to its own dedicated port on the hub. Hubs broadcast transmitted signals to all connected devices. You can connect multiple hubs to form a hierarchical star topology. The star topology uses the baseband signaling method.

    6. Chapter 2: NETWORK CABLING 6 A SIMPLE STAR TOPOLOGY

    7. Chapter 2: NETWORK CABLING 7 A HIERARCHICAL STAR TOPOLOGY

    8. Chapter 2: NETWORK CABLING 8 RING TOPOLOGY The ring topology can use twisted pair or fiber optic cabling. A central device (hub) connects hubs and nodes to the network. Each node connects to its own dedicated port on the hub. You can connect multiple hubs to form a larger ring. The ring topology uses the baseband signaling method. Frames are transmitted around the ring from node to hub to node. Media Access Control (MAC) is used for token passing.

    9. Chapter 2: NETWORK CABLING 9 A RING NETWORK

    10. Chapter 2: NETWORK CABLING 10 MESH TOPOLOGY Typically uses fiber optic cabling for redundant wide area network (WAN) links Provides multiple paths to destinations for fault tolerance Supports baseband and broadband signals Requires an enormous amount of cable

    11. Chapter 2: NETWORK CABLING 11 LAN MESH

    12. Chapter 2: NETWORK CABLING 12 ENTERPRISE MESH

    13. Chapter 2: NETWORK CABLING 13 WIRELESS TOPOLOGY Cell-based technology that uses unbounded media Two wireless topologies: Ad hoc Infrastructure

    14. Chapter 2: NETWORK CABLING 14 AD HOC WLAN

    15. Chapter 2: NETWORK CABLING 15 INFRASTRUCTURE WLAN

    16. Chapter 2: NETWORK CABLING 16 LAN CABLE TYPES Three cable types are used in LANs: Coaxial Twisted pair Fiber optic

    17. Chapter 2: NETWORK CABLING 17 COAXIAL CABLE

    18. Chapter 2: NETWORK CABLING 18 AUI (ATTACHMENT UNIT INTERFACE) CABLE

    19. Chapter 2: NETWORK CABLING 19 THIN ETHERNET HARDWARE

    20. Chapter 2: NETWORK CABLING 20 UNSHIELDED TWISTED PAIR (UTP) CABLE

    21. Chapter 2: NETWORK CABLING 21 UTP CONNECTORS

    22. Chapter 2: NETWORK CABLING 22 UTP CABLE GRADES

    23. Chapter 2: NETWORK CABLING 23 FIBER OPTIC CABLE

    24. Chapter 2: NETWORK CABLING 24 STRAIGHT TIP (ST) CONNECTOR

    25. Chapter 2: NETWORK CABLING 25 STRAIGHT THROUGH AND CROSSOVER WIRING Wiring within a twisted pair cable is configured as either Straight through, where each wire (or pin) is attached to the same contact point at each end Crossover, where transmit contacts on each end of the cable are connected to the receive contact at the other end

    27. Chapter 2: NETWORK CABLING 27 CROSSOVER WIRING

    28. Chapter 2: NETWORK CABLING 28 SUMMARY The three basic LAN topologies are bus, star, and ring. WLANs are becoming more popular. Mesh networks are not typically used in LANs. The primary cable types used in LANs are coaxial, twisted pair, and fiber optic.
