  5. 7 Application 6 Presentation 5 Session 4 Transport 3 Network 2 Data Link 1 Physical Model Layer Pada Jaringan • Mengurangi kompleksitas (satu masalah besar diubah dalam 7 bagian kecil ) • Menstandarkan antarmuka • Memudahkan belajar mengajar

  6. 7 Application 6 Presentation 5 Session 4 Transport 3 Network 2 Data Link 1 Physical NIC Card Fungsi Device pada Layer

  7. } 7 Application 6 Presentation 5 Session 4 Transport 3 Network 2 Data Link 1 Physical Host layers:Menyediakan data yang akurat yang dikirim antar komputer } Media layers:Mengontrol pengiriman pesan secara fisik antar jaringan Layer Host dan Media

  8. Application 7 Provides network services to application processes (such as electronic mail, file transfer, and terminal emulation) Fungsi Setiap Layer

  9. Application 7 Network services to applications Presentation 6 Data representation • Ensures data is readable by receiving system • Format of data • Data structures • Negotiates data transfer syntax for application layer Fungsi Setiap Layer

  10. Application 7 Network services to applications Presentation 6 Data representation Session 5 • Inter-host communication • Establishes, manages, and terminates sessions between applications Fungsi Setiap Layer

  11. Application 7 Network services to applications Presentation 6 Data representation Session 5 Inter-host communication 4 Transport • End-to-end connection reliability • Concerned with data transport issues between hosts • Data transport reliability • Establishes, maintains, and terminates virtual circuits • Fault detection and recovery • Information flow control Fungsi Setiap Layer

  12. Application 7 Network services to applications Presentation 6 Data representation Session 5 Inter-host communication 4 Transport End-to-end connection reliability 3 Network • Addresses and best path • Provides connectivity and path selection between two end systems • Domain of routing Fungsi Setiap Layer

  13. Application 7 Network services to applications Presentation 6 Data representation Session 5 Inter-host communication 4 Transport End-to-end connection reliability 3 Network Addresses and best path 2 Data Link • Access to media • Provides reliable transfer of data across media • Physical addressing, network topology, error notification, flow control Fungsi Setiap Layer

  14. Application 7 Network services to applications Presentation 6 Data representation Session 5 Inter-host communication 4 Transport End-to-end connection reliability 3 Network Addresses and best path 2 Data Link Access to media 1 Physical • Binary transmission • Wires, connectors, voltages, data rates Fungsi Setiap Layer

  15. Pengenalan Wireless Communication • Wireless communication (komunikasi tanpa kabel) digunakan ketika kabel tidak mungkin atau tidak layak dipasang/ditampilkan. • Media yang digunakan antara lain : • radio • gelombang mikro / microwave • bluetooth • IrDa, dll

  16. Wireless Media

  17. Radio • Sinyal dibawa dalam spektrum elektomagnetik • secara 2 arah (bidirectional) • Radio Broadcast : sinyal radio didistribusikan melalui jarak jauh dan dekat • Radio Cellular : bentuk dari radio broadcast yang digunakan untuk komunikasi bergerak

  18. Radio

  19. Microwave • Microwave station : • menggunakan antena pantul bumi (earth-based reflective dish) • harus ditransmisikan secara lurus tanpa halangan

  20. Microwave

  21. Komunikasi Satelit • Stasiun Luar Angkasa (space station) menerima sinyal gelombang mikro dari antena pantul bumi (earth-based reflective dish), menguatkan sinyal dan membroadcast sinyal kembali ke setiap stasiun bumi (earth-based station)

  22. Komunikasi Satelit
