laymen’s terms, Wi-Fi is the process of sending information wirelessly to your
devices can use Wi-Fi, e.g. personal computers, video-game consoles,
smartphones, digital cameras, tablet computers and
digital audio players. These can connect to a network resource such as the
Internet via a wireless network access point.
Such an access point (or hotspot)
has a range of about 20 meters (66 feet) indoors and a greater range outdoors.
be less secure than wired connections, such as Ethernet,
because an intruder does not need a physical connection. Wi-Fi has adopted various
encryption technologies to help with this. The early encryption WEP proved easy to
break. Higher quality protocols (WPA, WPA2) were added
later. The Wi-Fi Alliance has updated its test plan and certification
program to ensure all newly certified devices resist attacks.
Wi-Fi provides service in private homes, businesses, and
public spaces at Wi-Fi hotspots set up either free-of-charge or commercially.
Organizations and businesses, such as airports,
hotels, and restaurants, often provide free-use hotspots to attract customers.
Data security risk
order to maximize your security, you want to set up your Wi-Fi system to
operate using WPA or WPA2 encryption.Think of this as away to only allow people you give permission to use
your Wi-Fi. You don’t give everyone a copy of your house key and you shouldn’t
give everyone access to your computer and private information.
most common wireless encryption is WEP (Wired Equivalent Privacy), but it is
easy to break through even when set up the correct way. Most Wi-Fi is set to
automatically use this open mode lack of safety out of the box, mostly because
it is easy to plug it in and start using it.
