Study Notes
Home Network Basics
- Home networks typically comprise at least two networks: a public network from the service provider and a local network.
- Modems are essential devices that convert signals from the provider, enabling connectivity to the home network.
- Common modem types include cable modems for cable providers, which connect via coaxial cables.
Network Devices
- Home networking devices often combine modems and routers, with features like Ethernet ports for wired connections and built-in wireless access points.
- Routers separate local networks into wired and wireless segments, allowing devices to connect similarly, receiving IP addresses from the same subnet.
Common Devices Connected to Home Networks
- Devices commonly connected include desktop computers, gaming systems, smart TVs, printers, scanners, security cameras, telephones, and climate control devices.
- Increasingly, household technologies rely on network connectivity for functionality and control.
Networking Ports
- Small business and home routers typically feature two port types:
- Ethernet/LAN ports connect devices to the local network.
- Internet ports connect the router to external networks (e.g., cable or DSL modems).
Wireless Networking
- Home networks utilize wireless technologies primarily in the 2.4 GHz and 5 GHz frequency ranges.
- Bluetooth operates at 2.4 GHz for low-speed, short-range communications, commonly connecting peripherals and audio devices.
Wired Networking Technologies
- Ethernet is the most widely implemented wired protocol, supporting various wiring media and connections.
- Category 5e cabling is standard for LANs, made of twisted pairs to reduce interference, while coaxial and fiber-optic cables offer different advantages in speed and distance capabilities.
Wi-Fi Standards
- The IEEE 802.11 standard governs WLAN connectivity, dictating specifications for frequency use, data rates, and information transmission.
- The Wi-Fi Alliance certifies devices to ensure compatibility and adherence to wireless standards.
Network Configuration
- Wireless networks can use mixed modes to accommodate devices operating on different Wi-Fi standards.
- SSIDs (Service Set Identifiers) identify wireless networks, broadcasted by default for easy discovery by clients, though disabling this feature increases security challenges.
Network Security
- Encrypting wireless networks with robust security protocols is critical to preventing unauthorized access, even if SSID broadcasting is disabled.
