11 Pengertian : [Computer] Network
(terminal, komputer, server, sistem-lain) : yang saling terhubung sehingga mempermudah aliran data dan saling memakai resources. Kategori jaringan komputer : • LAN (local area network) / MAN (metropolitan AN) / WAN (wide AN) / VLAN (virtual LAN)/ VPN (virtual private network) / SAN (Storage AN, dedicated LAN/WAN untuk mass data storage and retrieval /System AN, high- performance & high-speed LAN dengan konfigurasi cluster) / CAN (Cluster / Controller AN) • Internet / Intranet / Extranet

12 LAN (local area network):
network yang memakai bersama sebuah atau/beberapa server disatu lokasi[kantor/gedung] yang membangun inter-office system MAN > LAN < WAN memakai dedicated / high performance hardware. WAN (wide area network) LANs yang saling terhubung dalam area luas Internet = WAN, extranet = WAN. perangkat beragam & mahal dibanding LAN. Teknologi pengembangan WAN: SONET, frame relay, dan ATM.

13 Pengertian : Internet Sistem informasi global yang:
Secara logikal saling terhubung oleh sebuah ruang adres unik global berbasis Internet rotocol (IP) atau ekstensi-nya; mampu menunjang komunikasi berbasis Transmission Control Protocol/Internet. Protocol (TCP/IP) atau ekstensi-nya, dan/atau protokol lain yang IP-compatible; dan dapat diakses, publicly atau privately.

14 (jaringan komputer) di mana situs-situs akademik, pemerintah, komersil, dan organisasi lain dapat melakukan: komunikasi langsung ( , chat) konferensi online (Usenet News, discussion lists) akses sumber informasi terdistribusi (World Wide Web, Gopher) remote login dan file transfer (telnet, ftp), dan lainnya.

15 Berbasis sekumpulan protocols baku, komputer yang tersambung memiliki domain name system (DNS) dan adres IP sendiri.

16 Pengertian : Intranet LAN yang diimplementasi teknologi WWW; atau
Private Internet: Private network enterprise, LAN saling terhubung & bisa terhubung pada WAN / internet melalui gateway. Para pegawai dapat memakai bersama informasi dan fasilitas komputasi, juga memfasilitasi working groups dan teleconferences. Implementasi TCP/IP, HTTP, dan IP lainnya. Pemakai dapat mengakses [Global / Public] Internet melalui firewall servers yang menyaring informasi yang mengancam company security.

17 Pengertian : Extranet Private network menggunakan IP & telecommunikasi publik untuk kerjasama bisnis dengan suppliers, vendors, partners, customers, lainnya. Dapat dipandang sebagai company's intranet yang diperluas untuk melayani pemakai mitra perusahaan.

18 Perlu keamanan dan privasi, menerapkan firewall server management:
user authentication encryption of messages use of virtual private networks (VPN) that tunnel through the public network.

19 Operasional Extranet Bertukar data volume besar dengan Electronic Data Interchange (EDI) / XML Berbagi katalog produk Berkolaborasi & bekerjasama dalam berbagai aktifitas bisnis Mengembangkan program pelatihan bersama Pelayanan oleh satu perusahaan bagi sekelompok perusahaan lain, misal online banking yang dikelola sebuah bank untuk bank-bank lain yang berafiliasi Berbagi berita yang menarik antar perusahaan

20 Dampak Internet dalam Masyarakat :
Akses sangat mudah, perolehan info relatif murah & banyak. Integrasi informasi, komunikasi, dan hiburan [+audio, video, multimedia] makin mempermudah penyampaian segala jenis pengajaran. Kebudayaan yang baik sangat mudah berpengaruh bila tanpa filter, pengaruh info negatif pada generasi muda > TV/radio. Agar info positif > negatif, peranan artist, scientist, & engineer sangat penting.

21 Komunitas Global Komunikasi tak dibatasi wilayah / kebangsaan / waktu Segala jenis data/info tersedia di berbagai jenis situs Berbagi kerja dan berkolaborasi mudah ilakukan oleh setiap individu dalam satu atau berbeda instansi / organisasi dalam satu atau berbeda bidang/minat.

22 Tersedia Shareware, Public Domain, Freely Copyable software programs yang dapay di-download Libraries, stores, and news groups untuk mencari tools atau informasi lainnya.

23 Penggunaan Internet : Pengadresan
Domain : kategori hirarki organisasi abstrak ke mana sebuah komputer/ situs / jaringan terdaftar, di mana top level: • com : perusahaan komersil • edu : institusi pendidian • gov : situs pemerintah • net : infrastruktur jaringan • org : organisasi non-komersil • us : situs di USA • id : situs di Indonesia Di bawah domain dapat tercantum banyak sub

24 Fasilitas Forum ~ electronic public meeting place untuk diskusi terbuka: Message-based Communications, one-to-many Electronic mail, one-to-one atau one-to-many Newsgroup, electronic bulletin board system created originally by the Unix community, misal Usenet News yang membahas banyak topik secara herarki [comp =komputer, rec rekreasi, soc = sosial, sci = sains, dll. Bulletin Board System (BBS), a computer + associated software, typically providing electronic messaging services, archives of files, and any other services or activities of interest to the BBS’s operator

25 Real-Time Communications ~ komunikasi di mana delay (net-lag) yang terjadi seminim mungkin, berbasis teks di mana tiap user memiliki special regions pada monitor [wilayah pengiriman dan penerimaan] Internet Relay Chat (IRC, WebChat), text- based mechanism communication with multiple participants. Multicasting, technical term that means that you can send pieces of data (packets), to multiple sites simultaneously. MUD [Multi-User Dungeon], an interactive game vironment where both real other players and virtual other players exist and with whom you can communicate to share ideas, solve puzzles, etc.

26 MUD, Dungeon ~ dungeon-like environment where evil goblins, demons, and other bad-guys are wandering around ready to kill Audio Video Conferencing, [teachers - students, doctors -patients, artists - audience] contoh CUSeeMe [Macintosh and Windows users with an Internet connection and a desktop camera to see, hear and speak with other CU-SeeMe users across the world; this program was developed at Cornell University in Ithaca, New York, USA and is freely available.]

27 Archive [Webster's] a place where public records, documents, etc. are kept a place where material having documentary interest, as private papers, institutional records, memorabilia, or photographs, is kept. Internet’s Archives are pretty much ~ exact same thing.

28 Searching memakai search engine
a program usually living on a remote computer that spends its time downloading information from other computers and building an index of what lives where [nickname = Web Crawler].

29 Contoh search engine Yahoo - Index of WWW sites, with search capabilities DejaNews - USENET (news groups) search engine WebCrawler - Lycos - AltaVista - WWW and USENET search engine Magellan - Index of reviewed and rated Internet sites, with search capabilities Google - Index of WWW sites, with search capabilities

30 World Wide Web ~ Web ~ subset of the computers di Internet
visualisasi Web sebagai rak giant magazine stand with a vast web of strings connecting various words pictures and ideas. organisasi Web tidak hirarkis, Web is broken up into a large set of pages (Web Pages), informasi dihubungkan dengan hypertext links. klik pada highlighted word / picture to call up a page of related information

31 Cara Akses internet : Akses Internet ~ receiving, downloading, and
viewing files, menggunakan same tools (SW&HW) needed to create files and make them available on the Internet; memerlukan dukungan: Internet Service Providers HW + SW + modem Web browser SW anti virus Perangkat akses multimedia: sound card + speakers, CD-ROM player, midi equip., video equip., printer

32 Tahapan Pengembangan Situs
Pembuatan & pendaftaran Kreasi isi : Getting help [lewat: Forum, BBS, Chat, dll.] Format file: public domain, proprietary, dll. Kreasi dokumen text & hyper text Kreasi citra grafik & animasi [format: bitmap, vector, video] Kreasi digital audio, suara & musik Publikasi Issues & Chalenges Security, viruses, standard disclaimer & copyrights & intellectual property (copyright, trademark, privacy, advicing), cryptography, netiquette.
