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 atelephone, current mobile phones can support many additional services such as SMS for text messagingemail,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).


The advanteges of mobile phones are: you can talk to people who are away from you, you can carry it with you so you dont miss important calls, if you are lost you can call for directions, if you had an accident you can call and if it has camera so you can take pictures of the accident that has happened, you can litsen to music, txt, playing games when youre bored, calculator, it has phone book

The disadvanteges of mobile phones are:it can damage your ear, its quite expensive, sometimes the reception is poor in some areas, you cant talk underground and in planes, people use bluetooth and the camera in bad ways, people use the phone while they are driving and this can couse problems.

Technology Hub 

A special type of network device called the hub can be found in many home and small business networks. Though they've existed for many years, the popularity of hubs has exploded recently, especially among people relatively new to networking. Do you own a hub, or are you considering purchasing one? This article explains the purpose of hubs and some of the technology behind
them.
General Characteristics of Hubs
A hub is a small rectangular box, often made of plastic, that receives its power from an ordinary wall outlet. A hub joins multiple computers (or other network devices) together to form a single network segment. On this network segment, all computers can communicate directly with each other. Ethernet hubs are by far the most common type, but hubs for other types of networks such asUSB also exist.
A hub includes a series of ports that each accept a network cable. Small hubs network four computers. They contain four or sometimes five ports, the fifth port being reserved for "uplink" connections to another hub or similar device. Larger hubs contain eight, 12, 16, and even 24 ports.
Key Features of Hubs
Hubs classify as Layer 1 devices in the OSI model. At the physical layer, hubs can support little in the way of sophisticated networking. Hubs do not read any of the data passing through them and are not aware of their source or destination. Essentially, a hub simply receives incoming packets, possibly amplifies the electrical signal, and broadcasts these packets out to all devices on the network - including the one that originally sent the packet!
Technically speaking, three different types of hubs exist:
  • passive
  • active
  • intelligent

 Bluetooth fever 

Bluetooth is managed by the Bluetooth Special Interest Group, which has more than 19,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. Bluetooth was standardized as IEEE 802.15.1, but the standard is no longer maintained. The SIG oversees the development of the specification, manages the qualification program, and protects the trademarks. To be marketed as a Bluetooth device, it must be qualified to standards defined by the SIG . A network of patents is required to implement the technology, which is licensed only for that qualifying device.
We wanted a technology that will allow us to essentially 'free the masses' and give everyone access to their music and movies. Bluetooth is the perfect technology for that."
Scott Troxel, Vice President of Marketing, Braven
Bluetooth is defined as being a short-range radio technology (or wireless technology) aimed at simplifying communications among Internet devices and between devices and the Internet. It also aims to simplify data synchronization between Internet devices and other computers.
Bluetooth products -- that is products using Bluetooth technology -- must be qualified and pass interoperability testing by the Bluetooth Special Interest Group prior to release. Bluetooth's founding members include Ericsson, IBM, Intel, Nokia and Toshiba.

Advantages of internet

*You have information at your fingertips, and you don't even have to know how to spell, or know your ABCs.
* Someone out there knows the answers to everything you can think of.
*You can send mail across the world within minutes where snail mail used to take 3-4 days in the states and 2 weeks overseas.
*You are connected to a lot of people who have similar interests if you know the right place to find them on the internet. A lot more difficult in person.
                                                             

 disadvantage of internet 


*The Internet is impersonal. You cannot see someone smile or react to your news or words though they may type it (grin).
*You cannot always trust the answers you get over the internet when you are looking for information.
*You spend too much time in front of a machine, and not enough time in front of "real" people.
 *You need a credit card if you want to buy something either to pay a third party sight, or to pay direct the company you are interested in. IN person, you can always pay by cash.

“Every social association that is not face-to-face is injurious to your health”

Global Dignity Day

Dignity is a state or quality of being worthy of honor or respect.On this day, Young Global Leaders and other role models join thousands of volunteers to do Dignity Days. They speak to youth in the Middle East, Europe, Asia, Africa and the Americas. Their aim is to instill a new, positive, inclusive and interconnected sense of value in young people that will guide them as they grow.At a Dignity Day session, facilitators – people who make the Dignity Principles their own – go into schools and talk with the pupils about dignity. Facilitators can be plumbers, health workers, bankers… in short, anyone that want to see young people become their best self can be a role model.
A typical Dignity Day session lasts about two hours. The facilitator usually starts by telling his or her own story about dignity. Then, the children are asked to define dignity in their own words. After discussing the Dignity Principles, the children tell their own stories in front of the class. Finally, they typically write a letter to themselves stating what they want to achieve for themselves and others through dignity. A year later, these letters are sent back to the students.

Our school even celebrated global dignity day,we gave a flower and a card which said "thank you"
to all our school peon's they were all so happy we wished every one a happy global dignity day. this is how i celebrated global dignity day.

I believe in the dignity of labor, whether with head or hand; that the world owes no man a living but that it owes every man an opportunity to make a living.
John D. Rockefeller 
The Sixth Annual Global Dignity Day is scheduled for Wednesday, October 16th, 2013, and will be celebrated in over 50 countries around the world.
Inspiring Action on a Worldwide Scale
During the 2005 Forum of Young Global Leaders, John Hope Bryant sat down with HRH Crown Prince Haakon of Norway and Professor Pekka Himanen of the University of Art and Design Helsinki and Oxford University. The topic of their conversation was something even more basic than financial literacy and economic justice: it was the concept of universal human dignity.

Each felt that our world was on the verge of a great opportunity for change. But to make it happen would require a fundamental shift in the attitudes, actions, and public policies supported by government figures at every level—toward assuring the dignity of each human being under their leadership
Global Dignity is the brainchild of three friends, concerned global citizens who met as Young Global Leaders at the World Economic Forum: HRH Crown Prince Haakon (Norway), Professor Pekka Himanen (Finland) and founder of Operation HOPE, John Hope Bryant (United States).
The three friends realized that the one thing that everyone in the world could agree on, irrespective of their differences is: We all want our Dignity to be recognized. Dignity is the very foundation of our humanity. Dignity is universal. Dignity is also the source of human rights.



Dignity consists not in possessing honors, but in the consciousness that we deserve them.



                                  Aristotle
