                                                            Cell- O- Mania



The mobile phone or mobile, also called a cellular phone, or cell phone is a long-range, portable electronic device used for mobile communication that uses a network of specialized base stations known as cell sites. In addition to the standard voice function of a telephone, current mobile phones can support many additional services such as SMS for text messaging, email, packet switching for access to the Internet, and MMS for sending and receiving photos and video. Most current mobile phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones).Nokia Corporation is currently the world's largest manufacturer of mobile telephones, with a global device market share of approximately 36% in Q1 of 2007.[4] Other mobile phone manufacturers include Apple Inc., Audiovox (now UT Starcom), Benefon, BenQ-Siemens, High Tech Computer Corporation (HTC), Fujitsu, Kyocera, LG Mobile, Mitsubishi, Motorola, NEC, Neonode, Panasonic (Matsushita Electric), Pantech Curitel, Philips, Research In MotionThere are significant questions as to who first invented the camera phone, as numerous other people received patents filed in the early 1990s for the device, including David M. Britz of AT&T Research in March of 1994 and Phillipe Kahn, who claims to have first invented it in 1997.[citation needed] The camera phone now holds 85% of the mobile phone market[citation needed]. Mobile phones often have features beyond sending text messages and making voice calls, including Internet browsing, music (MP3) playback, memo recording, personal organizer functions, e-mail, instant messaging, built-in cameras and camcorders, ringtones, games, radio, Push-to-Talk (PTT), infrared and Bluetooth connectivity, call registers, ability to watch streaming video or download video for later viewing, video calling and serve as a wireless modem for a PC, and soon will also serve as a console of sorts to online games and other high quality games (e.g. Final Fantasy Agito).[citation needed]

The mobile phone manufacturers can be grouped into two. The top five are available in practically all countries and comprise about 75% of all phones sold. A second tier of small manufacturers exists with phones mostly sold only in specific regions or for niche markets. The top five in order of market share are Nokia, Samsung, Motorola, SonyEricsson and LG.u

Top 10 inventions that changed the world

Top ten inventions that changed the world :
1. Wheel: Before the invention of the wheel in 3500 B.C., humans were severely limited in how much stuff we could transport over land, and how far. Wheeled carts facilitated agriculture and commerce by enabling the transportation of goods to and from markets, as well as easing the burdens of people traveling great distances.
2. Nail: Without nails, civilization would surely crumble. This key invention dates back more than 2,000 years to the Ancient Roman period. Meanwhile, the screw a stronger but harder-to-insert fastener is thought to have been invented by the Greek scholar Archimedes in the third century B.C.
3. Compass: The Chinese invented the first compass sometime between the 9th and 11th century; it was made of lodestone, a naturally-magnetized iron ore, the attractive properties of which they had been studying for centuries. 
4. Printing Press: The German Johannes Gutenberg invented the printing press around 1440. Printing Presses increased the speed of printing book copies.
5.Internal Combustion Engine: These engines, the combustion of a fuel releases a high-temperature gas, which, as it expands, applies a force to a piston, moving it. Thus, combustion engines convert chemical energy into mechanical work. 
6. Telephone: Alexander Graham Bell was the first to be awarded a patent for the electric telephone in 1876. The invention quickly took off, and revolutionalized global business and communication.
7. Light Bulb: Thomas Edison is credited as the primary inventor because he created a completely functional lighting system, including a generator and wiring as well as a carbon-filament bulb like the one above, in 1879.  Instead of going to bed at nightfall (having nothing else to do) and sleeping in segments throughout the night separated by periods of wakefulness, we now stay up except for the 7 to 8 hours allotted for sleep, and, ideally, we sleep all in one go.
8. Penicillin: It's one of the most famous discovery stories in history. In 1928, the Scottish scientist Alexander Fleming noticed a bacteria-filled Petri dish in his laboratory with its lid accidentally ajar. Penicillin was being mass produced and advertised by 1944. This poster attached to a curbside mailbox advised World War II servicemen to take the drug to rid themselves of venereal disease.
9. Internet: Internet is a source of knowledge, power and communicating. Mobile phones, datacards, hand held game consoles and cellular routers allow users to connect to the Internet wirelessly. We can see  people talking and walking on internet. It gives us alot of information and is accessible and affordable. We can buy thing by sitting at home and we can get latest news about anything. We can share our feelings and thoughts on internet.
10. Fridge: Before the invention of the refrigerator, ice houses were used to provide cool storage for most of the year. Placed near freshwater lakes or packed with snow and ice during the winter, they were once very common. Natural means are still used to cool foods today. On mountainsides, runoff from melting snow is a convenient way to cool drinks, and during the winter one can keep milk fresh much longer just by keeping it outdoors.

Internet = Blessing or a curse

Internet is a global system of interconnected computer networks. Internet is the " International Network". Today I am going to tell you about that internet is a blessing or a curse.
     
Internet is a source of knowledge, power and communicating. Mobile phones, datacards, hand held game consoles and cellular routers allow users to connect to the Internet wirelessly. We can see  people talking and walking on internet. It gives us alot of information and is accessible and affordable. We can buy thing by sitting at home and we can get latest news about anything. We can share our feelings and thoughts on internet.
Internet is a double-edged sword so there are its disadvantages also. It shows bad websites and pictures sometimes. Internet is full with fun things and games that can zap time away from a student who is working. Students waste there time on facebook or skype etc. Eyesights are highly effected by using internet too much. When you are focusing on one subject the ads on many websites defocus you and you start a new subject instead of which you have to do.

In my thinking Internet is a blessing because everyhing is good but its use make it good or bad so we should use it for good use.
