Study Notes
Networking Fundamentals
- A computer network connects two or more computers for communication.
- Each device on a network is called a node.
- Peripherals like printers and game consoles can be part of a network.
- Networked computers facilitate high-speed internet access, file sharing, and peripheral device use.
Network Architectures
- Networks are categorized based on distance, management, data exchange rules, and communication methods.
- Wide Area Network (WAN) covers a large geographical area.
- Metropolitan Area Network (MAN) encompasses a city or large town.
- Local Area Network (LAN) connects devices within a limited area like a home or office.
- Home Area Network (HAN) connects devices within a home.
- Personal Area Network (PAN) connects devices close to a person, like Bluetooth devices.
Network Components
- Transmission media (cables and wireless technology) connect network nodes.
- Hardware components enable communication between nodes and data transfer.
- Software allows the network to function properly.
Transmission Media
- Wired networks: use UTP cables (Category 5e, 6, and 6a).
- Wireless networks.
Basic Network Hardware
- Network adapters (NICs) connect devices to the network.
- Modems translate data signals.
- Routers forward data packets between networks.
- Switches connect devices within a network.
Network Software
- Operating systems enable networking functions like P2P communication and centralized server access.
Network Navigation Devices
- Routers transfer data packets between networks.
Home Networks
- Home networks often use specialized network operating systems (NOS).
Connecting to the Internet
- Home networks share internet access via Internet Service Providers (ISPs)
- Broadband (cable, DSL, fiber, satellite, and mobile) are common internet connection types.
Broadband Internet Connections
- Standard broadband, Satellite, and mobile broadband connections all connect to the internet.
Wired Broadband Internet Connection
- Cable, DSL, and fiber optic services are examples.
Wireless Internet Access
- Wi-Fi, mobile, and in-flight internet allow wireless connectivity.
Installing and Configuring Home Networks
- Connecting devices to a router
- Using NAS (Network-Attached Storage) devices.
- Specialised home networking devices - digital picture frames, wireless cameras.
Troubleshooting Wireless Networks
- Dual-band N routers offer enhanced wireless performance.
- Extending wireless range with extenders.
Securing Wireless Networks
- Using firewalls protects networks from unauthorized access.
