Network Resources

  1. 1. Networking Basics what you need to know…
  2. 2. What is a network? <ul><li>Physically a network consists of computers and other devices exchanging data. </li></ul><ul><li>The data can be transmitted through wires or broadcasted wirelessly. </li></ul><ul><li>Devices such as switches and routers and aid in the delivery of data by directing traffic and improving flow. </li></ul><ul><li>The network also includes the software through which the computer communicate. </li></ul>
  3. 3. The Main Types of Networks <ul><li>Local Area Network (LAN) </li></ul><ul><li>Wide Area Network (WAN </li></ul>
  4. 4. LAN <ul><li>A LAN is network connecting devices over a relatively small physical distance </li></ul><ul><li>Examples in our school: </li></ul><ul><ul><li>The file sever delivers your files over a LAN </li></ul></ul><ul><ul><li>The application server delivers applications to workstations over the LAN </li></ul></ul><ul><ul><li>These resources cannot be accessed outside of the building. </li></ul></ul>
  5. 5. WAN <ul><li>A relatively large network connecting devices. </li></ul><ul><li>The most prominent example is the Internet. (The World Wide Web is a subset of the Internet) </li></ul><ul><li>Another example is the public switched telephone network. </li></ul><ul><li>These resources can be accessed through any computer that is connected to the Internet. </li></ul>
  6. 6. LAN’s vs WAN’s <ul><li>WAN’s typically used a shared infrastructure while LAN’s are typically owned and operated by a single entity. (in our case – the school system.) </li></ul>
  7. 7. Network Infrastructure <ul><li>Networks are traditionally connected by wires, routers and switches </li></ul><ul><li>Wired networks are expensive and difficult to upgrade, improve and repair </li></ul><ul><li>Wireless networks are easier to install and upgrade </li></ul>
  8. 8. More about Wireless Networks <ul><li>Both LAN’s and WAN’s can be wireless </li></ul><ul><li>The Internet is predominately wired network, but many users access it wireless LAN. </li></ul>
  9. 9. Anywhere <ul><li>Vast and comprehensive wireless networks will allow us to: </li></ul><ul><li>“… realize the vision of location independence for the exchange of data… ” </li></ul><ul><li>Jeff Huskamp </li></ul><ul><li>Chief Information Office </li></ul><ul><li>East Carolina University </li></ul><ul><li>This means you will not need to be tied to a physical location to access networked resources </li></ul>
  10. 10. The truth about networks… <ul><li>While technically a network connects machines, in reality networks are used to connect people. </li></ul>
  11. 11. references <ul><li>Interview with Jeff Huskamp </li></ul><ul><li>http://portfolio. coe . ecu . edu /students/wsh0429/networking/interview.html </li></ul><ul><li>Local Area Network Basic Components </li></ul><ul><li>http://networkbits.net/lan-components/local-area-network-lan-basic-components/ </li></ul>
