question: A wireless network is a computer network that uses wireless data connections between network nodes.

Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.

Examples of wireless networks include cell phone networks, wireless local area networks (WLANs), wireless sensor networks, satellite communication networks, and terrestrial microwave networks.

The first professional wireless network was developed under the brand ALOHAnet in 1969 at the University of Hawaii and became operational in June 1971. The first commercial wireless network was the WaveLAN product family, developed by NCR in 1986.

Wireless personal area networks (WPANs) internet devices within a relatively small area, that is generally within a person's reach. For example, both Bluetooth radio and invisible infrared light provides a WPAN for interconnecting a headset to a laptop. ZigBee also supports WPAN applications. Wi-Fi PANs are becoming commonplace (2010) as equipment designers start to integrate Wi-Fi into a variety of consumer electronic devices. Intel "My WiFi" and Windows 7 "virtual Wi-Fi" capabilities have made Wi-Fi PANs simpler and easier to set up and configure.

Once upon a time, there was a dog named Puddles. Puddles was lonely because he lived in an area where there were no other dogs, but only cats. Day after day, Puddles would have to eat cat food and do cat things in order to fit in with the rest of his group. He found it very boring and Puddles was sad. Puddles didn't even look like a cat!

All of the other cats teased Puddles. "You're too big," they said. "You've got too long of a nose!" "Why are you panting like that?" Puddles knew that he was different.

One day, Puddles chose to run away from all of the cats. The cats laughed at him. What a stupid dog! Didn't he know that there were monsters in the woods that could eat him? Puddles didn't care, because Puddles was sad enough to try.

So Puddles packed up his things - his squeaky ball, his water dish, and his bone - and headed off into the woods. He was finally happy! All of a sudden, Puddles turned. He smelled a funny smell. It smelled like something he had never smelled before. He turned around, and what did he see but another dog!

input: Make use of the article to answer the questions. Jamie Oliver has been invited by Gordon Brown to prepare a banquet at No.10 for President Barack Obama and other leaders of the G20, offering a cut-price menu to reflect times when trade and industry are far from prosperous and the rate of employment is decreasing.

Downing Street sources say Oliver, the well-known chef, will cook using "honest high-street products" and avoid expensive or "fancy" ingredients.

The prime minister is trying to avoid a repeat of the embarrassment last year when he sat down to an 18-course banquet at a Japanese summit to discuss world food shortages.

Obama, President Nicolas Sarkozy of France, Chancellor Angela Merkel of Germany and other leaders will be served by apprentices from Fifteen, the London restaurant Oliver founded to help train young people in poverty in order to make a living by mastering a skill.

Brown wants the dinner to reflect the emphasis of the London summit, which he hopes will lead to an agreement to lift the world out of recession."To be invited to cook for such an important group of people, who are trying to solve some of the world's major problems, is really a privilege," said Oliver.

"I'm hoping the menu I'm working on will show British food and produce is some of the best in the world, but also show we have pioneered a high-quality apprentice scheme at Fifteen London that is giving young people a skill to be proud of."

The chef has not yet finalized me menu, but is expected to draw inspiration from his latest book, Jamie's Ministry of Food, which has budget recipes for beef and ale stew and "impressive" chocolate fudge cake. (
