541 week 3 networks

  1. 1. A Tutorial to Computer Networks in Educational Settings<br />By Julie Channell<br />
  2. 2. The Basics of Technology<br />Network<br />Information Technology Personnel role<br />Teacher role<br />
  3. 3. Network<br />Purpose<br /><ul><li>Connects multiple computers together to send and receive information when accessing the network
  4. 4. File server is the head of the network
  5. 5. large and fast computer that stores the RAM, extra memory, and stores software, applications, and files
  6. 6. All the other computers are called workstations
  7. 7. Involves hardware and software that connects computers and tools
  8. 8. Allows printers, scanners , email, and security features to be shared</li></li></ul><li>Network Operating Systems<br />There are two types of network operating systems:<br /><ul><li>Type 1- Peer to Peer
  9. 9. Type 2- Client Server</li></li></ul><li>Peer to Peer<br />Function<br />Equally small to medium local area networks (LAN)<br />Allows users to share resources and files<br />All computers are equal <br />Advantages<br />Start up cost is less<br />Little reconfiguration needed<br />Drawbacks<br /><ul><li>Not adequate security for network server
  10. 10. No central place for stored files</li></li></ul><li>Client Server<br />Function<br /><ul><li>Centralize functions and applications
  11. 11. The computers are considered clients and are connected to a server
  12. 12. File servers makes resources accessible and secure
  13. 13. Integrates all computers and files can be shared at the same time</li></ul>Advantages<br /><ul><li> All files are centralized and accessible
  14. 14. Elements can be replaced as needed
  15. 15. Components work together</li></ul>Drawbacks<br /><ul><li>Expensive and need staff to service and support it
  16. 16. When server goes down operations do not work</li></li></ul><li>Components of a Network<br />Components<br />Protocol- Everyone uses the same language<br /> Network Cards – Cards that are in the back of computers so information can be sent and received<br /> Cable- To connect the computers <br />Hub- To control the volume of users<br />Jelen, T. (2003)<br />
  17. 17. Network Continued<br />Local Area Network (LAN) – In a limited geographical area (building, library etc)<br />Wide Area Network (WAN)- Large geographical location (i.e. state)<br />
  18. 18. Diagram of a Network<br />Computer network diagram. (2010, August 27)<br />
  19. 19. Benefits from Having a Network in the Educational System<br />Appropriate school personnel can access student information simultaneously<br />Increase productivity time<br />Peer and educator collaboration and mentoring within the school and on the internet<br />Eases communication of staff, scheduling meeting, access curricular supports<br />
  20. 20. Hardware<br />Internal Hardware (inside the computer)<br /><ul><li>Hard drive- Stores your data
  21. 21. Motherboard- Main circuit board of the computer
  22. 22. Random Access Memory(RAM)- When a program is opened it is run from RAM, not the hard drive, since it is more efficient</li></ul>External Hardware- (Outside of the computer) <br /><ul><li>Network- Network interface cards and ethernet cards
  23. 23. Accessibility- Monitor, scanner, mice, keyboards, printers, scanners
  24. 24. Switch- Central point to connect workstations, cables, and servers
  25. 25. Router- Directs information within the network
  26. 26. Repeater-Boosts the strength of the connection of the cable</li></li></ul><li>Hardware Activity<br />The following activity is performed with teachers to familiarize themselves with the names/ part of the computer so they are able to more clearly identify their concerns when they call IT<br />http://www.eduplace.com/rdg/gen_act/g_start/computer.html<br />
  27. 27. Hardware Activity<br />
  28. 28. Software<br />Programs that run the computer (ie. Mouse skills, Type to Learn, SOLO, Kurzweil)<br />Have to check to see if they meet the system requirements<br /><ul><li>When hardware of software is purchased it is necessary to see if your computer will support it (memory, version, hard drive space)</li></li></ul><li>Internet vs Intranet<br />Internet- Interconnect global networks that allows millions of people to share information<br /><ul><li>No governing body regarding access or usage</li></ul>Intranet-Secure component of companies network to share information<br /><ul><li>Within an organization</li></li></ul><li>Information Technology (IT) Personnel <br />Relates to computer technology and supporting the use of it<br />Assist in maintaining and updating hardware and software<br />Support educators to learn tools so that they can be integrated into the educational environment <br />Activate personalization of accessibility features in students accounts for ease of access and use<br />
  29. 29. Educators Role<br />Use tools already on the computer and software installed<br />Monitor students and individualize software and settings to enhance student outcomes<br />Use grading tools, professionally network<br />Access lesson plans<br />Use technology in curricular areas<br />
  30. 30. Cheat Sheet Technology Problems<br />Is the tool plugged in<br />Is the battery charged<br />Restart the computer<br />Check the wireless connection<br />See if the disc/ software is loaded<br />Hard restart of the computer<br />Are too many programs open<br />Last error message be displayed- report that to IT<br />Most current updates before problems began- report to IT<br />
  31. 31. Examples of When to Contact IT<br />Need software installed<br />Need printer installed<br />Hardware not working<br />Constantly freezing<br />Updates needed on Antivirus or spyware<br />Network drives not working correctly<br />
