Transcript of "Networks "

  1. 1. Networks<br />Prepared by: Honey Mae Llanto<br />
  2. 2. Communication Over The Telephone Network <br />
  3. 3. Public Switched Telephone Network<br /> This is the worldwide telephone system that handles voice-oriented telephone calls.<br />
  4. 4. A sample telephone network configuration <br />
  5. 5. Dial-up lines<br />is a temporary connection that uses one or more analog telephone lines for communications.<br />
  6. 6. DedicatedLines<br /> is a type of always -on connection that is established between two communications devices.<br />can provide constant connection.<br />can either be analog or digital. <br />
  7. 7. Five Types of Digital Dedicated Lines<br />
  8. 8. ISDN Lines (Integrated Services Digital Network)<br /> is a set of standards for digital transmission of data over standard copper telephone lines.<br />provides faster transfer rates than dial-up telephone lines. <br />can carry three or more signals at once through the same line , using the technique called multiplexing. <br />
  9. 9. ISDN lines configuration<br />
  10. 10. DSL lines (Digital Subscriber Line)<br />transmits at fast speeds on existing standard copper telephone wiring.<br />may not be an option for rural residents because the user's location and the telephone company’s DSL modem must be located within 3.5 miles of each other . <br />popular types of DSL is the ADSL (Asymmetric Digital Subscriber Line).<br />
  11. 11. ADSL(Asymmetric Digital Subscriber Line) <br />is a type of DSL that supports faster transfer rates when receiving data than when sending data.<br />
  12. 12. DSL Lines Configuration<br />
  13. 13. FTTH and FTTB Lines<br />FTTH(Fiber to the Home) uses fiber-optic cable to provide extremely high –speed Internet access to home users.<br />FTTB(Fiber to the Building ) refers to small businesses that use fiber-optic cables to access the internet. <br />
  14. 14. T-Carrier Lines<br />is any of several types of long-distance digital telephone lines that carry multiple signals over a single communications line.<br />
  15. 15. Types of T-carrier Lines<br />T1 line- refers to a specific type of copper or fiber optic telephone line that can carry more data than the traditional telephone lines .<br />Fractional T1 line- allows a customer to use only a certain number of the 24 channels on a T1 line.<br />T3 line- is equal in speed to 28 T1 lines, and is used by larger businesses with higher data and voice demands.<br />
  16. 16. ATM(Asynchronous Transfer Mode)<br />is a service that carries voice, data, video, and multimedia at very high speeds.<br />
  17. 17. Communication Devices<br />
  18. 18. Communication Devices<br />is any type of hardware capable of transmitting data, instructions, and information between a sending device and a receiving device.<br />
  19. 19. Typesof Communication Devices<br />
  20. 20. Dial-Up Modems<br />is a type of modem used to connect a personal computer to the internet.<br />usually it is in the form of an adapter card that you insert in an expansion slot on a computer’s motherboard. <br />it is sometimes called modem.<br />
  21. 21. ISDN Modems<br />Digital modem- is a modem that sends and receives data and information to and from a digital telephone line such as IDSN and DSL. <br />IDSN modems- sends digital data and information from a computer to an ISDN line and receives data and information from an IDSN line.<br />
  22. 22. DSL Modem<br />DSL modems- sends digital data and information from a computer to a DSL line and receives digital data and information from a DSL line. <br />
  23. 23. Cable Modems<br />sometimes called broadband modem.<br />Is a digital modem that sends and receives digital data over the cable television(CATV) network.<br />
  24. 24. A typical cable modem installation<br />
  25. 25. Wireless Modems<br />allows access to the web wirelessly from a notebook computer, a PDA, a smart phone, or any mobile devices.<br />
  26. 26. Network Cards<br />enables the computer or device that does not have built-in networking capability to access a network. <br />coordinates transmission and receipt of data, instructions, and information to and from computer or device. <br />
  27. 27. Variety of Network Cards<br />
  28. 28. PC card<br />is the form of peripheral interface designed for laptop computers.<br />
  29. 29. Express Card Module<br />slots into a computer system to allow the addition of hardware capabilities.<br />
  30. 30. USB Network Adapter<br />these adapters connect to a standard USB port available on the back of most newer computers.<br />not much larger in size than PC adapters.<br />
  31. 31. Flash card<br />is a set of cards bearing information, as words or numbers, on either or both sides, used in classrooms drills or in private study. <br />
  32. 32. Wireless Network Card<br />is a new technology that slots into a computer system to allow the addition of hardware capabilities.<br />
  33. 33. Wireless Access Point<br />is a central communication device that allows computers and devices to transfer data wirelessly among themselves or to transfer data wirelessly to a wired network.<br />
