06 jaringan komputer Presentation Transcript

  • 1. PENGANTAR ILMU KOMPUTER Komunikasi Data dan Jaringan Komputer 12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 2. Sistem Komunikasi Data
    • Melibatkan minimal 2 simpul
      • Simpul bisa berupa komputer maupun peralatan lain
      • Simpul berperan sebagai pengirim dan/atau penerima data
    • Dihubungkan oleh media transmisi
    • Data yg ditransmisikan berupa isyarat listrik
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 3. Gangguan Komunikasi Data
    • Data yg sampai kepada penerima bisa tidak sama dg yg disampaikan pengirim
    • Penyebab Utama
      • Atenuasi
        • Pelemahan sinyal akibat jarak
      • Distorsi Tunda
        • Pengaruh pada waktu penerimaan
      • Derau
        • Penambahan data yg tidak perlu pada saat transmisi data
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 4. Arah Transmisi
    • Menyatakan arah isyarat dalam media transmisi
      • Simplex / One way
        • Tidak dapat bertindak sebagai pengirim dan penerima sekaligus
      • Half-Duplex
        • Mengirim dan menerima data bergantian
      • Full-Duplex
        • Mengirim dan menerima data berbarengan
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 5. Media Transmisi
    • Penghubung antara pengirim dan penerima u/ melewatkan data
      • Media kabel
      • Media nirkabel
    • Media Kabel
      • Twisted Pair Cable
        • UTP
        • STP
      • Coaxial
      • Fiber Optic
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 6. Jaringan Komputer
    • Hubungan dua atau lebih komputer yang bertujuan u/ melakukan pertukaran data
    • Memungkinkan berbagi sumberdaya
    • Jenis jaringan menurut rentang geo
      • LAN
        • Mencakup area yg terbatas (<1 Km)
      • MAN
        • Mencakup area dg rentang satu kota (10-45 Km)
      • WAN
        • Menghubungkan antar kota atau lebih luas lagi.

  • 7. Topologi Jaringan
    • Susunan komputer secara fisik dalam suatu jaringan
      • Bus
      • Ring
      • Star
      • Extended Star
      • Hierarchial
      • Mesh
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 8. Bus Topology
    • All of its nodes connected directly to one link
      • No other connections between nodes
      • Each host is wired to a common wire.
    • One advantage of this topology is that all hosts are connected to each other, and thus, can communicate directly.
    • One disadvantage of this topology is that a break in the cable disconnects hosts from each other.
    • Enables all networking devices to see all signals from all other devices
      • Traffic problems and collisions are common.
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 9. Ring Topology
    • Single closed ring consisting of nodes and links.
      • Each node connected to only two adjacent nodes.
      • All devices wired directly to each other.
    • In order for information to flow, each station must pass the information to its adjacent station.
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 10. Star Topology
    • Has a central node with all links to other nodes radiating from it and allows no other links.
    • Its primary advantage is that it allows all other nodes to communicate with each other, conveniently.
    • Its primary disadvantage is that if the central node fails, the whole network becomes disconnected..
    • The flow of all information would go through one device.
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 11. Extended Star Topology
    • Repeats a star topology, except that each node that links to the center node is, also, the center of another star.
    • The advantage of this is that it keeps wiring runs shorter, and limits the number of devices that need to interconnect to any one central node.
    • An extended star topology is very hierarchical, and information is encouraged to stay local
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 12. Hierarchical Topology
    • Similar to the extended star topology
      • uses a trunk node from which it, then, branches to other nodes.
    • The trunk is a wire that has several layers of branches.
    • The flow of  information is hierarchical.
    12/13/11 Zulfadli Sulthan - PTIK - UNM
  • 13. Mesh Topology
    • Every node is linked directly to every other node.
    • The advantages are that
      • Should any link fail to function, information can flow through any number of other links to reach its destination.
      • Allows information to flow along many paths on its way through the network.
    • The primary physical disadvantage is the amount of media for the links, and the amount of connections to the links becomes overwhelming.
    • Depends greatly on the devices used.

  • 14. Perangkat Interkoneksi Antarjaringan
    • Interkoneksi Antarjaringan
      • Hubungan antara dua buah jaringan atau lebih.
    • Perangkatnya
      • Repeater / Hub
      • Bridge / Switch
      • Router
