Network Hardware Project

  1. 1. The Basic Computer Network-Hardware<br /> within Mountain High School<br />
  2. 2. presented by Karen Kelly<br /> for Ed Tech 541<br />
  3. 3. Introduction<br />Demographics<br />Mountain High School has a<br />Staff ~ 45 <br />Student population ~ 800 <br />Relatively diverse population (International Program and Student Exchange Program)<br />A high percentage of students that move on to College and University after graduation.<br />School Objective<br /> “To utilize technology to improve engagement”. <br />School Needs<br /> " To be able to provide our 21st Century learners with the tools they need to learn in today's modern world." <br />
  4. 4. So how is itconnected?<br />
  5. 5. How is it possible to…<br />
  6. 6. Lets take a look…<br />
  7. 7. First: Some basic terminology….<br />
  8. 8. Network<br /> Computers linked to ‘share’ information.<br />Minimum - 2 computers<br />Maximum - ?<br />
  9. 9. TCP/IP<br /> Transmission Control Protocol/Internet Protocol<br /> The standards/rules for computers so they can communicate within networks. <br />
  10. 10. ISP<br />Internet Service Provider<br />Required in order to connect to the Internet.<br />Example:Shaw<br />
  11. 11. Second: The Goods ….<br />
  12. 12. Our school uses a <br />Local Area Network or LAN. <br />LAN’s typically <br />Have higher data transfer<br />rates, <br />Are used with smaller geographic ranges, and <br />Lack the need for leased telecommunication lines. <br />
  13. 13. Our school is connected to the district through a WAN (Wide Area Network)<br />The connection is to the Shaw cable server.<br />It connects larger geographical regions.<br />Each of the Personal Area Networks (or PAN) in our classrooms are connected to the LAN in our school.<br />
  14. 14. All of the rooms in our school are wired with Ethernet technology and use category 5 (Cat5) cable. <br /> This is then connected to longer coaxial (galvanic) cable that leads to the routers. <br />
  15. 15. All Ethernet connections<br /> Understand IP protocol. <br /> Are connected to a central or‘top’ access distribution router that connects to the<br /> the Intranet and Internet.<br />
  16. 16. Intranet<br />The internal school network of organizational information.<br />Controlled by administration. <br />Specifies authorized users. <br />Uses the Internet Protocol and IP based tools.<br />Has one web server.<br />Protected from being accessed from the Internet without proper authorization. <br />
  17. 17. The Internet<br />Is a worldwide interconnection of networks. <br />Uses Internet Protocol (IP) Suite. <br />Is the communications base for the World Wide Web (WWW).<br />Is not considered to be a part of the Intranet.<br />
  18. 18. Basic Hardware<br />On Computers (or Workstations)<br />A NIC (Network Interface Card)<br />An Ethernet jack to plug in Ethernet cable.<br />Devices (To Interconnect network nodes)<br />Cables-connect Ethernet cable from computers to router.<br />File Sever – Computer at heart of LAN which controls network.<br />Switches – repeat signals over short distances to router. <br />Router-translates and sends info to correct place in the world.<br />NIC<br />Ethernet Jack<br />Cable<br />Switches<br />Router<br />
  19. 19. Basic Software<br />On Computers<br />Web browser software<br />HTTP (Hypertext Transfer Protocol) (An Internet-based protocol for sending and receiving webpages.)<br />Web browser Software<br />
  20. 20. Examples: Library, 3 Computer Labs, Office, and Staff Computers in each classroom.<br />Have<br />Wired LAN connecting PC’srunning a protocol (IEEE 802.3) through a system of interconnected devices and eventually connect to the Internet. <br />Library<br />Computer Labs<br />
  21. 21. The library network is a branching tree topology and controls access to resources.<br /> All wired PC’s, have access to<br />Internet, <br />Card catalogue, and<br />The local printer.<br />All user computers, have only access to <br />Internet.<br />Branching Tree Topology<br />
  22. 22. The staff computers, in each classroom, all can<br />Access and use a limited part of the school network including attendance and reporting records.<br />Use Internet <br />Access the library, and<br />Use the local printer.<br />
  23. 23. Several of the rooms in our school are also connected to wireless technology. (WLAN)<br />These devices use high-frequency radio wave ‘spread spectrum’ technology for transmission.<br />Wireless<br />
  24. 24. Examples: Library, and Student Multipurpose Room<br />Have<br />Wireless LAN for users to interconnect local devices and to connect to the internet. <br />Do Not Have<br />Access to a printer or<br />Access to the school network.<br />
