Transcript

  • 1. LANs
  • 2. WANs
  • 3. Network Models
    Peer-to-peer Networking Model
    A peer-to-peer network is a decentralized network model offering no centralized storage of data or centralized control over the sharing of files or resources. All systems on a peer-to-peer network can share the resources on their local computer as well as use resources of other systems.
    Client/Server Networking Model
    The client/server networking model is, without question, the most widely implemented model and the one you are most likely to encounter when working in real-world environments. The advantages of the client/server system stem from the fact that it is a centralized model. It allows for centralized network management of all network services, including user management, security, and backup procedures.
  • 4. Comparison of Networking Models
  • 5. Network Topologies
    A topology refers to both the physical and logical layout of a network. The physical topology of a network refers to the actual layout of the computer cables and other network devices. The logical topology of a network, on the other hand, refers to the way in which the network appears to the devices that use it.
  • 6. Bus Topology
    A bus network uses a trunk or backbone to which
    all of the computers on the network connect. 
  • 7. Ring Topology
    The ring topology is actually a logical ring, meaning that the data
     travels in circular fashion from one computer to another on the network.
  • 8. Star Topology
    In the star topology, all computers and other network devices
     connect to a central device called a hub or switch.
  • 9. Mesh Topology
    The mesh topology incorporates a unique network design in which each
    computer on the network connects to every other, creating a
    point-to-point connection between every device on the network. 
  • 10. IEEE and Networking Standards
    The Institute of Electrical and Electronic Engineers (IEEE) developed a series
    of networking standards to ensure that networking technologies developed
    by respective manufacturers are compatible.
