One of the greatest revolutionary innovations of the twentieth century is Internet. The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies.
Rapidly, there is a dramatic change in the way we communicate, do business, educate ourselves and entertain ourselves. Perhaps even the architects of Internet would not have foreseen the tremendous growth rate of the network being witnessed today. It made the ‘global village utopia ‘ a reality in a rather short span of time.
Using the internet it is easy for the people to exchange ideas, resources and information. Likewise there are millions of users to the Internet and the drawback of the Internet is that it cannot adequately support many services being imagined, such as interconnection of gigabit networks with lower bandwidths, high security applications and interactive virtual reality applications.

What is WiFi?
Wi-Fi, which stands for wireless fidelity, in a play on the older term Hi-Fi, is a wireless networking technology used across the globe. Wi-Fi refers to any system that uses the 802.11 standard, which was developed by the Institute of Electrical and Electronics Engineers (IEEE) and released in 1997. The term Wi-Fi, which is alternatively spelled WiFi, Wi-fi, Wifi, or wifi, was pushed by the Wi-Fi Alliance, a trade group that pioneered commercialization of the technology.
In a Wi-Fi network, computers with wifi network cards connect wirelessly to a wireless router. The router is connected to the Internet by means of a modem, typically a cable or DSL modem. Any user within 200 feet or so (about 61 meters) of the access point can then connect to the Internet, though for good transfer rates, distances of 100 feet (30.5 meters) or less are more common. Retailers also sell wireless signal boosters that extend the range of a wireless network.
Wifi networks can either be “open”, such that anyone can use them, or “closed”, in which case a password is needed. An area blanketed in wireless access is often called a wireless hotspot. There are efforts underway to turn entire cities, such as San Francisco, Portland, and Philadelphia, into big wireless hotspots. Many of these plans will offer free, ad-supported service or ad-free service for a small fee. San Francisco recently chose Google to supply it with a wireless network.

The internet security experts M86, who uncovered the scam, estimate that at least £675,000 has been illegally transferred from the UK in the last month – and that the attacks are still continuing.
