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.
