The in-flight internet, or AI, is a communication network installed on different types of aircraft. It eliminates the need for land-based infrastructure, allowing communication and information to flow even if ground-based facilities are inoperable. It has benefits in emergency situations and military strategies, as well as improving safety for commercial airlines. The technology has evolved […]
A wireless access point broadcasts a Wi-Fi signal that mobile devices can connect to, often for free. They are found in businesses and can be created by consumers through their mobile carrier. Some are restricted for employee use and utility companies are implementing city-wide hotspots. A wireless access point, or hotspot, is a location that […]
WiFi networks use radio waves to connect computers and share online access without cabling. They require a router and WiFi card or adapter, and use the IEEE 802.11 standard. Different generations of protocols exist, and components must support the same type to communicate. Certified components are recommended for business networks. Bluetooth networks use a weaker […]
Using someone else’s wireless Internet service can be risky as the network owner can see almost everything. Encryption is necessary to secure the LAN from eavesdropping and prevent freeloading. Users should assign unique usernames and passwords for each registered site and avoid illegal activities. With the availability of public hot spots and neighborhood wireless networks […]
Find free WiFi hotspots by searching online directories before leaving home. Verify availability and network type with the establishment beforehand. Use a WiFi finder device or visit coffee shops, bookstores, airports, hotels, and city buildings for access. Wi-Fi Alliance sets international wireless standards. As online activities increasingly integrate with real-world activities, the number of places […]
WiFi is a wireless communication standard used for local area networks. It allows devices to share files and resources, and can create hot spots for public access. WiFi networks are easy to set up and require a NIC card. Different versions of the standard exist, with varying speeds and frequencies. Security is important and can […]
WiFi is a wireless networking technology that uses the 802.11 standard and allows devices to connect wirelessly to a network or gain access to the internet. WiFi networks can be open or closed with a password, and efforts are underway to turn entire cities into massive WiFi hotspots. WiFi technology uses radio signals to communicate […]
Using someone else’s wireless service without permission is theft, but may not always be unethical if permission is given. It can slow down the owner’s internet and compromise security. Sharing with neighbors or during service issues is acceptable. Using someone else’s wireless service is really theft, as it involves using a resource that someone else […]
Wireless networks connect computers and peripherals without wires, allowing for easy communication. The 802.11 standard is used by almost all wireless networks, with subsections indicating speed and technology. Newer standards, such as 802.11(g) and 802.11(n), offer increased range and speed. WiMax is another type of wireless network that can extend for hundreds of miles, while […]
A wireless local area network (WLAN) uses radio waves to connect two or more computers, while a wired LAN uses Ethernet cables. The server connects to the DSL modem and clients require wireless NICs. WLANs offer convenience and flexibility, but require protection against intrusion and can be slower and less reliable than wired networks. The […]
Free WiFi hotspots are public places where anyone can access the internet, but they can be unsafe as they are often unencrypted and can be intercepted by malicious people. Users should avoid visiting websites that send usernames, passwords, or plain text emails and use reputable anti-virus and anti-spyware software. It is safe to use hotspots […]
A router directs traffic between computers on wired or wireless networks. Wireless networks are cheaper and easier to set up, but require a wireless router. A modem is needed for internet access, which can be combined with a wireless router. Different wireless standards exist, with 802.11n being the fastest. Dual-band routers support both 2.4g and […]
