What is Domain Name Registration or Domain Name or Domain Registration ?

A Domain name is a specific Internet address that furnishes specific identity to the registrant of their domain name. A domain name is the name of a website located at a numerical IP address on web. With the vast amounts of information on the Internet, a domain name is easier to remember than a long string of numbers. The only characters allowed are letters, numbers and hyphens. No other punctuation marks or spaces are allowed in domain names. Domain names must have less than 63 characters. Domain names can not begin or end with a hyphen. It starts with www and ends with the domain extensions like .com, .org, .net, .info, .edu, .in, .co.uk, .co.in, .ca and more.

Domain registration is the process by which a company or individual can secure a website domain name, such as www.yoursite.com. Once you have completed domain registration the domain becomes yours for the period of the contract, usually one year is the time frame given by all the registrant. Before registration expires it must be renewed, or the domain reverts back to being available to the general public.

What is Wi-Fi or WiFi and it's use?

Wi-Fi is a trademark of the Wi-Fi Alliance for certified products based on the IEEE 802.11 standards. The term Wi-Fi is often used by the public as a synonym for wireless LAN (WLAN); but not every wireless LAN product has a Wi-Fi certification, which may be because of certification costs that must be paid for each certified device type.

Wi-Fi is supported by most personal computer operating systems, many game consoles, laptops, smartphones, printers, and other peripherals. If you've been in an airport, coffee shop, library or hotel recently, chances are you've been right in the middle of a wireless network.

Many people also use wireless networking, also called WiFi or 802.11 networking, to connect their computers at home, and some cities are trying to use the technology to provide free or low-cost Internet access to residents. In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires.

They're also unobtrusive -- unless you're on the lookout for a place to use your laptop, you may not even notice when you're in a hotspot.
