    Networking Networking Presentation Transcript

    • LANs
    • WANs
    • 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.
    • Comparison of Networking Models
    • 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.
    • Bus Topology
      A bus network uses a trunk or backbone to which
      all of the computers on the network connect. 
    • 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.
    • Star Topology
      In the star topology, all computers and other network devices
       connect to a central device called a hub or switch.
    • 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. 
    • 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.
