Understanding Wireless Networks

What is the main function of a router?

• To encrypt data for secure transmission.

• To provide internet access to devices.

• To store data packets for later use.

• The main function of a router is to direct data packets between different networks.

How does a Wi-Fi access point differ from a router?

• A Wi-Fi access point is used for wired connections, while a router is for wireless connections.

• A router only manages local traffic, while an access point manages internet traffic.

• A Wi-Fi access point connects wireless devices to a wired network, while a router manages traffic between networks.

• A router connects devices to the internet, while an access point connects to other access points.

What is the purpose of a wireless repeater?

• To secure a wireless network by encrypting the signal.

• To extend the range of a wireless network by amplifying the signal.

• To provide a wired connection to devices in a wireless network.

• To increase the speed of a wireless network by reducing latency.

What does SSID stand for in wireless networking?

• Single Service Identifier

• Service Set Identifier

• Service Set Indicator

• Secure Set Identifier

What is the typical range of a standard Wi-Fi signal?

• 50 feet (15 meters) indoors and 100 feet (30 meters) outdoors for 2.4 GHz; 30 feet (9 meters) indoors for 5 GHz.

• 150 feet (46 meters) indoors and 300 feet (91 meters) outdoors for 2.4 GHz; 100 feet (30 meters) indoors for 5 GHz.

• 200 feet (61 meters) indoors and 400 feet (122 meters) outdoors for 2.4 GHz; 150 feet (46 meters) indoors for 5 GHz.

• 100 feet (30 meters) indoors and 200 feet (61 meters) outdoors for 2.4 GHz; 75 feet (23 meters) indoors for 5 GHz.

What frequency bands do most Wi-Fi networks operate on?

• 2.0 GHz and 7.5 GHz

• 4.9 GHz and 6.2 GHz

• 2.4 GHz and 5 GHz

• 1.2 GHz and 3.5 GHz

What is the significance of WPA2 in Wi-Fi security?

• WPA2 is only relevant for wired networks.

• WPA2 is a type of hardware used in routers.

• WPA2 is primarily used for network speed enhancement.

• WPA2 is significant for providing robust security and encryption for Wi-Fi networks.

How can you improve the signal strength of your Wi-Fi?

• Change the Wi-Fi password frequently

• Reposition the router, reduce interference, use extenders, upgrade antennas, and update firmware.

• Use a microwave near the router

• Increase the number of devices connected

What is the difference between 2.4 GHz and 5 GHz Wi-Fi?

• 2.4 GHz has longer range and lower speeds; 5 GHz has shorter range and higher speeds.

• 2.4 GHz and 5 GHz have the same range and speed.

• 2.4 GHz is only used for gaming; 5 GHz is for streaming.

• 2.4 GHz has shorter range and higher speeds; 5 GHz has longer range and lower speeds.

What device would you use to extend the range of your Wi-Fi network?

• Wi-Fi extender or repeater

• Ethernet cable

• Network switch

• Wi-Fi router
