Study Notes

Network Topologies

  • Definition: Network topology describes the physical and logical arrangement of computers and devices in a network.
  • Physical Topology: Refers to the actual layout of network cables and devices.
  • Logical Topology: Concerns how the network is perceived by the devices using it.

Wired Topologies

  • Bus Topology:

    • Connects all devices using a single backbone or trunk.
    • Devices tap into the cable to access transmitted packets.
    • Requires terminators at both ends to prevent signal reflection.
    • Considered outdated, with no need for a hub or switch.
  • Ring Topology:

    • Each device connects to two others, forming a circular pathway for data packets.
    • If one device or segment fails, the entire network can be compromised.
    • Also does not require a hub or switch.

Wireless Topologies

  • Infrastructure Wireless Topology:

    • Devices connect through a central device, like a wireless router.
    • Common in home and office environments for internet access.
  • Ad Hoc Wireless Topology:

    • Direct communication between devices without a central access point.
    • Useful in temporary scenarios like meetings or small gatherings.
  • Wireless Mesh Topology:

    • All devices are interconnected, allowing multiple communication paths.
    • Highly reliable as communication can be rerouted if one node fails.
  • Hybrid Topology:

    • Combines various wireless topologies for flexibility and resilience.
    • Example includes a mix of point-to-point and mesh networks.

Geographical Network Types

  • Local Area Network (LAN):

    • Operates within a limited geographic area, such as an office or school.
  • Wireless Local Area Network (WLAN):

    • A LAN that uses wireless technology.
  • Wide Area Network (WAN):

    • Covers a large area; connects multiple LANs.
    • Slower than LANs, requiring more complex and expensive hardware.
  • Metropolitan Area Network (MAN):

    • Serves a specific geographic area like a city.
    • Larger than a LAN, smaller than a WAN.
  • Campus Area Network (CAN):

    • Connects multiple LANs within a defined area, such as a university campus.
  • Storage Area Network (SAN):

    • Connects shared storage devices, offering block-level data storage.
  • Personal Area Network (PAN):

    • For personal devices like smartphones and tablets, often using Bluetooth or NFC.

Router & Switch Devices

  • Router:

    • Connects different network segments, directing data between them.
    • Example: Home router linking a user to the internet.
  • Switch:

    • Connects multiple computers within a network via cables.
    • Forwards data only to the relevant port based on MAC addresses.

Routing

  • Definition: The process of directing data packets between networks.

  • Router Role: Makes decisions on the most efficient data paths at the network layer.

  • Static Routing:

    • Manually configured routing tables, suitable for stable networks.
    • Simple but less adaptable to dynamic changes.
  • Dynamic Routing:

    • Routers exchange information to automatically update routes.
    • Efficient for large networks subject to frequent changes.

Switching Methods

  • Packet Switching:
    • Breaks data into smaller packets for transmission, enhancing efficiency.
