Overview Komunikasi Data dan Jaringan
1 - 1
A Communications Model
• Source• generates data to be transmitted
• Transmitter• Converts data into transmittable signals
• Transmission System• Carries data
• Receiver• Converts received signal into data
• Destination• Takes incoming data
1 - 2
Networking
• Point to point communication not usually practical
• Devices are too far apart
• Large set of devices would need impractical number of connections
• Solution is a communications network
• Wide Area Network (WAN)
• Metropolitan Area Network (MAN)
• Local Area Network (LAN)
1 - 4
Wide Area Networks
• Large geographical area
• Crossing public rights of way
• Rely in part on common carrier circuits
1 - 5
Local Area Networks
• Smaller scope
• Building or small campus
• Usually owned by same organization as attached devices
• Data rates much higher
• Usually broadcast systems
1 - 6
LAN Configurations
• Switched
• Switched Ethernet
• May be single or multiple switches
• Wireless
• Mobility
• Ease of installation
1 - 7
Metropolitan Area Networks
• MAN
• Middle ground between LAN and WAN
• Private or public network
• High speed
• Large area
1 - 8
Outline
• Brief history of Data Communications• Communications, Information Systems and the Internet
• Data Communications Networks• Network components, network types
• Network Models• OSI model, Internet model, transmission via “layers”
• Network Standards• Standards making, common standards
1 - 9
Information Age
• First Industrial Revolution• Introduction of machinery
• New organizational methods
• Changed the way people worked
• Second Industrial Revolution – Information Age• Introduction of computers
• Introduction of networking and data communication
• Changed the way people worked again
• Faster communication Collapsing Information lag
• Brought people together Globalization

ThreeParts to Understanding Networking
1. Concepts of networking• How data moves from one computer to another over a
network
• Theories of how networks operate
2. Technologies in use today• How theories are implemented, specific products
• How do they work, their use, applications
3. Management of networking technologies• Security
• Network Design
• Managing the network1 - 11
