Transcript

  • 1. Networks
    Prepared by: Honey Mae Llanto
  • 2. Communication Over The Telephone Network
  • 3. Public Switched Telephone Network
    This is the worldwide telephone system that handles voice-oriented telephone calls.
  • 4. A sample telephone network configuration
  • 5. Dial-up lines
    is a temporary connection that uses one or more analog telephone lines for communications.
  • 6. DedicatedLines
    is a type of always -on connection that is established between two communications devices.
    can provide constant connection.
    can either be analog or digital.
  • 7. Five Types of Digital Dedicated Lines
  • 8. ISDN Lines (Integrated Services Digital Network)
    is a set of standards for digital transmission of data over standard copper telephone lines.
    provides faster transfer rates than dial-up telephone lines.
    can carry three or more signals at once through the same line , using the technique called multiplexing.
  • 9. ISDN lines configuration
  • 10. DSL lines (Digital Subscriber Line)
    transmits at fast speeds on existing standard copper telephone wiring.
    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 .
    popular types of DSL is the ADSL (Asymmetric Digital Subscriber Line).
  • 11. ADSL(Asymmetric Digital Subscriber Line)
    is a type of DSL that supports faster transfer rates when receiving data than when sending data.
  • 12. DSL Lines Configuration
  • 13. FTTH and FTTB Lines
    FTTH(Fiber to the Home) uses fiber-optic cable to provide extremely high –speed Internet access to home users.
    FTTB(Fiber to the Building ) refers to small businesses that use fiber-optic cables to access the internet.
  • 14. T-Carrier Lines
    is any of several types of long-distance digital telephone lines that carry multiple signals over a single communications line.
  • 15. Types of T-carrier Lines
    T1 line- refers to a specific type of copper or fiber optic telephone line that can carry more data than the traditional telephone lines .
    Fractional T1 line- allows a customer to use only a certain number of the 24 channels on a T1 line.
    T3 line- is equal in speed to 28 T1 lines, and is used by larger businesses with higher data and voice demands.
  • 16. ATM(Asynchronous Transfer Mode)
    is a service that carries voice, data, video, and multimedia at very high speeds.
  • 17. Communication Devices
  • 18. Communication Devices
    is any type of hardware capable of transmitting data, instructions, and information between a sending device and a receiving device.
  • 19. Typesof Communication Devices
  • 20. Dial-Up Modems
    is a type of modem used to connect a personal computer to the internet.
    usually it is in the form of an adapter card that you insert in an expansion slot on a computer’s motherboard.
    it is sometimes called modem.
  • 21. ISDN Modems
    Digital modem- is a modem that sends and receives data and information to and from a digital telephone line such as IDSN and DSL.
    IDSN modems- sends digital data and information from a computer to an ISDN line and receives data and information from an IDSN line.
  • 22. DSL Modem
    DSL modems- sends digital data and information from a computer to a DSL line and receives digital data and information from a DSL line.
  • 23. Cable Modems
    sometimes called broadband modem.
    Is a digital modem that sends and receives digital data over the cable television(CATV) network.
  • 24. A typical cable modem installation
  • 25. Wireless Modems
    allows access to the web wirelessly from a notebook computer, a PDA, a smart phone, or any mobile devices.
  • 26. Network Cards
    enables the computer or device that does not have built-in networking capability to access a network.
    coordinates transmission and receipt of data, instructions, and information to and from computer or device.
  • 27. Variety of Network Cards
  • 28. PC card
    is the form of peripheral interface designed for laptop computers.
  • 29. Express Card Module
    slots into a computer system to allow the addition of hardware capabilities.
  • 30. USB Network Adapter
    these adapters connect to a standard USB port available on the back of most newer computers.
    not much larger in size than PC adapters.
  • 31. Flash card
    is a set of cards bearing information, as words or numbers, on either or both sides, used in classrooms drills or in private study.
  • 32. Wireless Network Card
    is a new technology that slots into a computer system to allow the addition of hardware capabilities.
  • 33. Wireless Access Point
    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.
  • 34. Wireless access point configuration
  • 35. Router connections
  • 36. Connecting Networks
  • 37. Hub or Switch
    is a central point that connects several devices in a network together.
  • 38. Hub or Switch connections
  • 39. Home Networks
    saves the home user money and provides many conveniences.
  • 40. Wired Home Networks
  • 41. Types of Wired Home Networks
    • Ethernet
    • 42. Powerline Cable Networks
    • 43. Phoneline Networks
  • Ethernet
    is a standard communication protocol embedded in software and hardware devices, intended for building a local area network(LAN).
  • 44. Powerline Cable Network
    is a network that uses the same lines that bring electricity into the house.
  • 45. Powerline Cable Network configuration
  • 46. Phoneline Network
    is an easy-to-stall and inexpensive network that uses existing telephone lines in the home.
  • 47. Phoneline Network configuration
  • 48. Wireless Home Networks
    is typically a system that allows personal computers to communicate with one another and often, with the internet.
  • 49. Wireless home network configuration
  • 50. TYPES
    HomeRF(radiofrequency)
    Uses radio waves, instead of cables to transmits data.
  • 51. HomeRF configuration
  • 52. Wi-Fi network
    enables devices such as personal computer ,mobile phones etc. to connect to the internet when range of wireless network connected to the internet.
  • 53. How to set up hardware for a Wi-Fi Home Network
  • 54. Steps
  • 55.
  • 56. Communication Channels
  • 57. Bandwidth
    Is the amount of data , instructions, or information that can travel over a communication channel.
    Latency
    Is the time it takes a signal to travel from one location to another on a network.
  • 58. Transmission Media
    Consist of materials or substances capable of carrying one or more signal.
    Baseband Media
    Transmits only one signal.
    Broadband Media
    Transmit multiple signals simultaneously.
  • 59. Types of Transmission Media
    Physical Transmission Media
    Wireless Transmission Media
  • 60. Physical Transmission Media
    used in communications include twisted- pair cable, coaxial cable, and fiber- optic cable.
  • 61. Transmission Media used in communication
    • Twisted-Pair Cable
    • 62. Coaxial Cable
    • 63. Fiber-Optic cable
  • Twisted-pair cable
    Consist of one or more twisted-pair wires bundled together .
  • 64. Coaxial cable
    Consist of a single copper wire sorround3d by at least three layers: (1.) an insulating material,(2.) a woven or braided metal, and (3.) a plastic outer coating.
  • 65. Fiber- optic cable
    Consist of dozens or hundreds of thin strands of glass or plastic that use light to transmit signals.
  • 66. This is Honey Mae Llanto saying……………
    “Do not follow where the path may lead. Go instead where there is no path and leave a trail.”
