A Router is a device that forwards data packets along networks and also provides internet.
LAN= local area network, WAN= Wide area network.
Wi-Fi is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed internet connections. Wi-Fi is also known as "Wireless Local Area Network" (WLAN)
Router that incorporate a digitai subscriber line modem or a cable modem and a Wi-Fi access point, often set up in homes and other buildings, provides internet access and internetworking to all devices connected to them, wirelessly or via cable.
Types of Routers
1) Asymmetric Digital Subscriber Line (ADSL Router)- can be used for broadband internet provider. It comes without a modem and the input is via the LAN connection. Comes with Wireless-N technology that lets user share single broadband internet connection. It can be easily installed and wireless printing can be done.
2) Asymmetric Digital Subscriber Line Two Plus (ADSL 2+ Router)- can be used where internet is provided through telephone line (MTNL & BSNL). Its come with an inbuilt modem and the input port is the telephone port. This too can be easily installed and aids in wireless printing.
Upstream and Downstream Network
In upstream network traffic flows away from the local Computer toward the remote destination. Conversely, downstream traffic flows to the user's computer Traffic on most networks flows in both upstream and downstream directions simultaneously.
N- Network The wireless N Router is a way to wirelessly connect the networked devices in your home to the internet. All N-certified routers are backward compatible i.e.it supports b and g network.. Wireless-N Router comes with 802.11n technology offering data transfer rates from 150 Mbps to 750Mbps allowing streaming of HD movies, music, other multimedia content
Single and Dual Band Router
Single-band Router communicate using the 2.4GHz frequency spectrum where as dual-band Router can communicate on two frequencies 2.4GHz and 5GHz simultaneously.
Dual-band Router can be useful if you're experiencing interference with neighbouring Wi-Fi signals.
Information Superhighway: Wireless N achieves higher data rates by adding extra lanes and creating more room for traffic flow

Wi-Fi Security
The growth of the internet is highly dependent on security. With the ever increasing internet traffic, the need for keeping the communication secure and protected is essential. Wi-Fi alliance has put in place WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access ll) protocols to secure Wi-Fi networks, these protocols cover:- Data Integrity makes sure that the original data was not inspected/modified by a third party while the data is in flight from source to destination. Received content is same as the Sent content.
- Data Source Authentication makes sure that the data received is from the claimed sender.
- Data Content confidentiality makes sure that the data is only known to the intended recipients. Only the Sender and Receiver can view the content.
