- What Are the Advantages of a Wireless Home Network?
Anytime, anywhere connectivity without cable limitations.
Easy and inexpensive to install.
New users can join quickly without additional setup
- What Devices Commonly Connect to a Home Network?
Desktop computers
Gaming systems
Smart TVs
Printers & scanners
Security cameras
Telephones
Climate control devices
- What Are the Main Ports on a Home Router?
Ethernet Ports (LAN): Connect to internal network devices.
Internet Port (WAN): Connects the router to the internet via a modem.
- What Is the Electromagnetic Spectrum?
The electromagnetic spectrum includes radio waves, visible light, X-rays, and gamma rays.
Some frequencies are unlicensed for public use, such as Wi-Fi.
- What Wireless Frequencies Are Used in Home Networks?
2.4 GHz Band: Used for Bluetooth and Wi-Fi (IEEE 802.11b/g/n).
5 GHz Band: Used for modern Wi-Fi (IEEE 802.11n/ac/ax).
- What Are the Main Wired Network Technologies?
Category 5e Ethernet Cable: The most common LAN wiring, consisting of twisted pairs to reduce interference.
Coaxial Cable: Has an insulated core surrounded by a conducting shield.
Powerline Ethernet: Uses electrical wiring in a house to extend a network.
- What Are the Wireless Standards for Home Networks?
IEEE 802.11: Governs Wi-Fi standards.
Wi-Fi Alliance: Tests wireless devices for compatibility.
- What Are Key Wireless Network Settings?
Network Mode: Defines supported Wi-Fi standards (e.g., 802.11b/g/n).
SSID (Network Name): Identifies the Wi-Fi network.
Standard Channel: Determines which frequency channel is used.
SSID Broadcast: Controls whether the network name is visible to nearby devices.
- How Are Wireless Channels Used?
Divides the RF spectrum to allow multiple conversations.
Multiple APs can work together using different channels.
5 GHz networks can combine channels for higher speeds.
- How Does Ethernet Handle Collisions?
Uses Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA).
Devices request a channel using Request to Send (RTS) messages.
The Access Point (AP) responds with Clear to Send (CTS).
After communication, an ACK message is sent to release the channel.
- How Do You Set Up a Home Router?
Connect an Ethernet cable from a computer to the router’s LAN port.
Connect the router’s internet port to the DSL/cable modem.
Check the NIC link lights to confirm connection.
The router assigns an IP address using DHCP.
- What Are Important Design Considerations for a Home Network?
Choose a secure SSID that does not reveal network details.
Ensure device compatibility with Wi-Fi standards.
Use MAC Address Filtering to restrict device access.
