  1. Jaringankomputer Pertemuan 4

  2. Konsep TI HARDWARE SOFTWARE Jaringankomputer Internet&web Basis data Sisteminformasi multimedia Interoperabilitasdankeamanan Pemanfaatan IT

  3. Mengapa butuh jaringan komputer ??? Stand alone Computer …. Untuk Apa ???

  4. JARINGAN KOMPUTER Def:kolaborasiantara minimal duabuahkomputer Prinsip: Menggunakansuatuprotokolkomunikasi Terdiridarikomputer server dankomputer client

  5. Kantor Sebelum Menggunakan Sistem Jaringan Komputer :

  6. Kantor Setelah Menggunakan Sistem Jaringan Komputer :

  7. KEUNTUNGAN • Easiness • No distance • Mobility • Efficient

  8. Keuntungan Good salary Control other peoples Faster than others Relax Kerugian ERROR, then people want to kill YOU !!! Network Administrator,…

  9. Study… • Teori Dasar Jaringan • OSI Layer • Network devices • Routing • Network security • Programming

  10. Study… • Network Skill • Operating system • Server – Client • Router, Switch, Cabling, etc (network devices) • Hacking not Cracking • Certificate • Experience • Time can answer ???

  11. KEUNTUNGAN PENGGUNAAN JARINGAN KOMPUTER Sharing. Komunikasi Manajemen data yang tersentralisasiolehseorang Supervisor / Administrator. Sistemkeamananterjamin

  12. SISTEM KEAMANAN DATA YANG TERJAMIN • Data umumdapatdipakaibersama-sama • Data-data rahasiadiproteksi. • Aksesditentukanoleh administrator • Data setiap user bisadiakses/dieditseijin administrator

  13. JARINGAN MENURUT RENTANG GEOGRAFIS LAN (Local Area Network) MAN (Metropolitan Area Network) WAN (Wide Area Network) PAN (Personal Area Network),

  14. PAN (PERSONAL AREA NETWORK)

  15. LOCAL AREA NETWORK

  16. METROPOLITAN AREA NETWORK

  17. WIDE AREA NETWORK

  18. KOMPONEN PEMBENTUK JARINGAN Personal komputer Media Transmisi Network Interface Card Connector Software Jaringan Software Aplikasi Media Penyimpanan Data

  19. Berdasarkanmetodekoneksi C-S P-P

  20. Bus topology

  21. Topologi ring

  22. Topologi star

  23. Tree topology

  24. Mesh Topology

  25. Extended star topology

  26. Data Komunikasi

  27. KOMPONEN KOMUNIKASI DATA Komputer host Komputer receiver Data Protokolkomunikasi

  28. protokol Syntax Semantic timing

  29. Fungsiprotokol Fragmentasi Encapsulasi Connection control Flow control Error control Transmition service

  30. Application Application Presentation Session Transport Transport Network Network Data-link Data-link Physical Physical OSI Layer 7 Layer/OSI TCP/IP

  31. Header Data Header Data Application • Contoh : Email, HTTP, dsb Format Data Analogi

  32. Header Header Data Data Header Payload Header Presentation & Session • Security, Compression • RPC, RMI Analogi

  33. Dumy Header Payload PL PL PL PL PL PL PL 2 5 7 4 3 1 6 PL PL PL PL PL PL PL Transport • PL = PayLoad • TCP, UDP Protocol

  34. Header 1 2 2 3 1 4 6 5 3 4 5 6 Transport Layer Analogi • Paket besar dibagi-bagi menjadi paket-paket yang lebih kecil • Masing-masing paket diberi nomor sesuai dengan urutannya

  35. Address PL 2 7 1 3 4 6 5 PL PL PL PL PL PL PL Network Layer • Address pada Network Layer dinamakan : Logical Address • Address terdiri dari : Source Address (alamat IP pengirim, mis:172.16.180.16), dan Destination Address (alamat IP penerima, mis: 192.234.13.201)

  36. 2 3 1 4 6 5 4 Pengirim Penerima Pengirim Penerima Network Layer Analogi • Router

  37. Address PL Address PL Address Address Address PL PL PL Address PL Data-link Paket kecil Paket besar • Address pada Data-link disebut: Physical Address • Address terdiri atas: Source Address (Alamat Asal), dan Destination Address (Alamat Tujuan) • Source dan Destination address adalah alamat point (titik) sesaat yang dituju, dan bukan alamat IP.

  38. Asal Asal Asal Tujuan Pengirim Pengirim Pengirim Tujuan Tujuan Penerima Penerima Penerima Data-link • Jika ukuran paket kecil • Jika ukuran paket besar • Eth card, Switch

  39. PC PC Asal 1 0 Tujuan Physical Layer • Hub, repeater
