What is WiFi And How It Works?

Wi-Fi is a popular wireless networking technology. Wi-Fi stands for “wireless fidelity”. The Wi-Fi was invented by NCR corporation/AT&T in Netherlands in 1991. By using this technology we can exchange the information between two or more devices. Wi-Fi has been developed for mobile computing devices, such has laptops, but it is now extensively using for mobile applications and consumer electronics like televisions, DVD players and digital cameras. There should be two possibilities in communicating with the Wi-Fi connection that may be through access point to the client connection or client to client connection. Wi-Fi is a one type of wireless technology. It is commonly called as wireless LAN (local area network). Wi-Fi allows local area networks to operate without cable and wiring. It is making popular choice for home and business networks. A computer’s wireless adaptor transfers the data into a radio signal and transfers the data into antenna for users.

Working:

Wi-Fi is a high speed internet connection and network connection without use of any cables or wires. The wireless network is operating three essential elements that are radio signals, antenna and router. The radio waves are keys which make the Wi-Fi networking possible. The computers and cell phones are ready with Wi-Fi cards. Wi-Fi compatibility has been using a new creation to constituent within the ground connected with community network. The actual broadcast is connected with in sequence in fact it is completed by way of stereo system surf as well as the worth of wires with monitor to classification prone. Wi-Fi allows the person in order to get access to web any place in the actual provided area. You can now generate a system within Resorts, library, schools, colleges, campus, personal institutes, as well as espresso stores as well as on the open public spot to help to make your company much more lucrative as well as interact with their own customer whenever. Wi-Fi compatibility can make surf with stare to company using their inspiring cable television much a smaller amount force down.

Many new laptops, mobile phones have inbuilt Wi-Fi card you don’t have to do any thing which is one of the best thing. If it is a free- based type of network connection the user will be promoted with a login id and password. The free base network connections also well in some areas. The Wi-Fi network connection is creating hot spots in the cities. The hot spots are a connection point of Wi-Fi network. It is a small box that is hardwired in to the internet. There are many Wi-Fi hot spots available in public places like restaurants, airports, and hotels offices, universities etc.
Security is impartment element in the Wi-Fi technology. Security is our personal decision but having a wireless connection we should pay attention to protect our private details. We can connect easily to unsecured wireless routers. The problem is any one is connected to your wire less router using the data like download games, download apps and planning terrorist activities, shirring illegal music and movie files etc. So it is necessary to provide security to the wireless technologies based devices.


What is WiFi Router?

A WiFi router, also referred to as a wireless router, is an electronic networking device that forwards data packets between computer networks, thus providing Internet access to multiple devices connected to it. In simple words, it is a machine that sends ‘Internet’ from a cable to a device, and also acts as a wireless access point, allowing the data it’s getting through a cable to be shared with the connected devices wirelessly.

Working of WiFi router:

First, you need to know how a router works. Essentially, a router connects your home computers in a local area network (LAN) and then routes packets intended for the Internet (email, web, etc.) through your router to your ISP’s (Internet Service Provider) actual connection to the big bad Internet. It also receives packets intended for your computer from the Internet by sending them to your router. Your router then determines if this packet in for you and, if so, sends it on to your computer. Routers will have one wired (ethernet) connection to your ISP’s modem (called the WAN for Wide Area Netork). Routers also have several wired connections, usually 4 or more, that go to individual computers.
A WiFi router has all the above plus additional LAN ports available on the wireless channels that it broadcasts such that you can now connect several wireless devices such as smartphones and laptops to your router to get a connection to the Internet as described above.

What is WiFi Adapter?

A wireless adapter is a hardware device that is generally attached to a computer or other workstation device to allow it to connect to a wireless system. Before the advent of consumer devices with built-in Wi-Fi connectivity, devices required the use of wireless adapters to connect to a network.
Wireless adapters are also known as Wi-Fi adapters.
Wireless adapters often come in USB stick form, which must be plugged into a USB port of a computer or device. USB has become a universal standard for all sorts of accessory devices that plug into a computer or workstation device. Wireless adapters may also come in the form of PCI network cards that plug into a PCI slot on the computer motherboard. They do not generally plug into the Ethernet port. Instead, an Ethernet cable can connect a computer directly to a router or other device.
New technology has made wireless adapters somewhat obsolete, as new generations of portable computers generally have built-in wireless connectivity that can be enabled or disabled as needed.

What is WiFi Hostspot?

A WiFi hotspot is simply an area with an accessible wireless network. The term is most often used to refer to wireless networks in public areas like airports and coffee shops. Some are free and some require fees for use, but in either case they can be handy when you are on the go. You can even create your own mobile hotspot using a cell phone or an external device that can connect to a cellular network. And you can always set up a WiFi network at home.
If you want to take advantage of public WiFi hotspots or your own home-based network, the first thing you'll need to do is make sure your computer has the right gear. Most new laptops and many new desktop computers come with built-in wireless transmitters, and just about all mobile devices are WiFi enabled. If your computer isn't already equipped, you can buy a wireless adapter that plugs into the PC card slot or USB port. Desktop computers can use USB adapters, or you can buy an adapter that plugs into the PCI slot inside the computer's case. Many of these adapters can use more than one 802.11 standard.

What Is Wifi Card?

Wireless Internet cards, also known as Local Area Network, or LAN, cards, are one of the many types of adapter cards that add capabilities to your computer. Other adapter cards can enable teleconferencing, improve sound systems or download photos from a digital camera.
Wireless Internet cards come in several forms. Different cards exist for laptops, desktops and PDAs. Many computers come with one preinstalled, but they can also be purchased relatively inexpensively and self-installed or simply inserted into a slot on the side of the computer.
The sheer number of WiFi hot spots has made wireless Internet cards even more desirable. Initially used mostly in homes or businesses so that multiple people could share an Internet connection, they are a hot commodity for anyone with a computer, especially with entire cities going wireless.

what is wifi link speed?

link speed is the maximum speed in bits per second that your device can communicate with the device that it is linked to. In most cases this will be the link speed between your device and the router. For Ethernet connections, common link speeds are either fast Ethernet (100 Mbps) or Gigabit (1000 Mbps).
In most cases, you'll find that this average is only about 30-60% of what is advertised. For instance, if you're paying for 8Mbps, you'll normally find that your average speed is somewhere between 2-3 Mbps. Those using a 10Mbps connection usually only register between 3-4Mbps which is less than what they pay for.

What is Wifi Mac Address?

To access the Registered network, the hardware or MAC address of wireless card must be registered with the network as a form of authentication.
A MAC address contains 12 characters, with digits from 0 to 9, and letters from A to F. The letters may be either upper or lower case. Sometimes each pair of characters is separated by a colon, dash or a space. Sometimes there is no spacer at all.
When you locate your MAC address WiFi, copy and paste if you can, otherwise carefully write it down. Depending on the font used, certain characters can look very similar. For instance, B, 3, 8, 6 might be easily confused. The network will check the registered address against the address your computer sends on the network so it has to be exactly the same.
