8 JARINGAN DALAM BANYAK UKURAN

9 CLIENTS DAN SERVERS

10 PROVIDING RESOURCES IN A NETWORK PEER-TO-PEER

11 Ada 3 kategori dalam jaringan: 1 perangkat 2.Media 3. Services LAN, WAN, DAN INTERNETS KOMPONEN DALAM JARINGAN

12 KOMPONEN JARINGAN PERANGKAT JARINGAN Beberapa contoh dari end devices adalah : Computers (work stations, laptops, file servers, web servers) Network printers VoIP phones TelePresence endpoint Security cameras Mobile handheld devices (seperti smartphones, tablets, PDAs, and wireless debit / credit card readers and barcode scanners)

13 COMPONENTS OF A NETWORK PERANGKAT INFRASTRUKTUR JARINGAN Contoh dari intermediary network devices adalah: Network Access Devices (switches, and wireless access points) Internetworking Devices (routers) Security Devices (firewalls)

14 COMPONENTS OF A NETWORK MEDIA TRANSMISI

15 COMPONENTS OF A NETWORK REPRESENTASI JARINGAN

16 COMPONENTS OF A NETWORK TOPOLOGI JARINGAN

18 LANS AND WANS JENIS-JENIS JARINGAN The two most common types of network infrastructures are: Local Area Network (LAN) Wide Area Network (WAN). Other types of networks include: Metropolitan Area Network (MAN) Wireless LAN (WLAN) Storage Area Network (SAN)

19 LANS AND WANS LOCAL AREA NETWORKS (LAN)

20 LANS AND WANS WIDE AREA NETWORKS (WAN)

21 LANS, WANS, AND INTERNETS INTERNET

22 THE INTERNET INTRANET AND EXTRANET

23 LANS, WANS, AND INTERNETS TEKNOLOGI INTERNET AKSES

24 CONNECTING TO THE INTERNET CARA KONEKSI KE INTERNET

25 CONNECTING TO THE INTERNET KONEKSI BISNIS/PERUSAHAAN KE INTERNET

26 CONVERGED NETWORKS KONVERGENSI JARINGAN

27 CONVERGED NETWORKS PERENCANAAN UNTUK MASA DEPAN

28 RELIABLE NETWORK PENDUKUNG ARSITEKTUR JARINGAN As networks evolve, we are discovering that there are four basic characteristics that the underlying architectures need to address in order to meet user expectations: Fault Tolerance Scalability Quality of Service (QoS) Security

29 JARINGAN SIRKUIT SWITCH

30 RELIABLE NETWORK JARINGAN PAKET SWITCH

31 RELIABLE NETWORK PENSKALAAN JARINGAN

32 RELIABLE NETWORK PENYEDIAAN (QOS) Examples of priority decisions for an organization might include: Time-sensitive communication - increase priority for services like telephony or video distribution. Non time-sensitive communication - decrease priority for web page retrieval or . High importance to organization - increase priority for production control or business transaction data. Undesirable communication - decrease priority or block unwanted activity, like peer-to-peer file sharing or live entertainment

33 RELIABLE NETWORK PENYEDIAAN KEAMANAN JARINGAN

34 NETWORK TRENDS TREN BARU Some of the top trends include: Bring Your Own Device (BYOD) Online collaboration Video Cloud computing

35 NETWORK TRENDS BRING YOUR OWN DEVICE (BYOD)

36 NETWORK TRENDS ONLINE COLLABORATION

37 NETWORK TRENDS VIDEO COMMUNICATION

38 NETWORK TRENDS CLOUD COMPUTING There are four primary types of clouds: Public clouds Private clouds Custom clouds Hybrid clouds

39 NETWORK TRENDS DATA CENTERS A data center is a facility used to house computer systems and associated components including: Redundant data communications connections High-speed virtual servers (sometimes referred to as server farms or server clusters) Redundant storage systems (typically uses SAN technology) Redundant or backup power supplies Environmental controls (e.g., air conditioning, fire suppression) Security devices

40 NETWORKING TECHNOLOGIES FOR THE HOME TREN TEKNOLOGI JARINGAN DI PERUMAHAN

41 NETWORKING TECHNOLOGIES FOR THE HOME JARINGAN POWER LINE

42 NETWORKING TECHNOLOGIES FOR THE HOME WIRELESS BROADBAND

43 FUTURE OF NETWORKING KEAMANAN JARINGAN

44 NETWORK SECURITY ANCAMAN KEAMANAN The most common external threats to networks include: Viruses, worms, and Trojan horses Spyware and adware Zero-day attacks, also called zero-hour attacks Hacker attacks Denial of service attacks Data interception and theft Identity theft

45 NETWORK SECURITY SOLUSI KEAMANAN Network security components often include: Antivirus and antispyware Firewall filtering Dedicated firewall systems Access control lists (ACL) Intrusion prevention systems (IPS) Virtual Private Networks (VPNs)

46 EXPLORING THE NETWORKING KESIMPULAN In this chapter, you learned: Networks and the Internet have changed the way we communicate, learn, work, and even play. Networks come in all sizes. They can range from simple networks consisting of two computers, to networks connecting millions of devices. The Internet is the largest network in existence. In fact, the term Internet means a network of networks. The Internet provides the services that enable us to connect and communicate with our families, friends, work, and interests.

47 EXPLORING THE NETWORKING KESIMPULAN In this chapter, you learned: The network infrastructure is the platform that supports the network. It provides the stable and reliable channel over which communication can occur. It is made up of network components including end devices, intermediate device, and network media. Networks must be reliable. Network security is an integral part of computer networking, regardless of whether the network is limited to a home environment with a single connection to the Internet, or as large as a corporation with thousands of users.

48 EXPLORING THE NETWORKING KESIMPULAN In this chapter, you learned: The network infrastructure can vary greatly in terms of size, number of users, and number and types of services that are supported on it. The network infrastructure must grow and adjust to support the way the network is used. The routing and switching platform is the foundation of any network infrastructure.
