Introduction We are here to present you a presentation on Mobile Phones BY- MR. Rahul and MR. Anas So without wasting time Lets jump right into it Whole World of Phones The common factor Which is not a factor now a days This thing is found in every hand of A human now from a small child to a Old aged man. Cellphones are a faster and more effective Way to transfer an information. Indeed, it is A resource that give it’s user’s great advantages. They say, if something is of great utility (usage, etc), it will surely have its own problems as well. Disadvantages of Mobile phones Cell phone is playing an important role in this modern world. It is very hard to see a person without a mobile phone. Even a little kid have the ability to access the cell phone fluently without any problem. Kids are very much interested in playing games in mobile phone and spending a lot of time with it. As we know too much of cell phone usage is not good for us and it will give some unwanted health issues. Cell phone will create some unwanted radiation which is not good for our brain. A person who is using Mobile for a long time will surely get health issues due to it. We must control our Mobile activities. Avoid using it for a long time and use it whenever necessary . Some people especially teens get so much addicted for talking, video , messaging , games etc that they forget the real purpose of phone and waste large part of their time in unnecessary Interaction over their cell phones Nothing can be a distraction for a teacher in the classroom. When a student’s phone rings . Cell phones are increasingly a problem for the schools during classrooms hours and are becoming A means of cheating during examinations and other kinds of ability tests. All this is really bad And hurt the future of the students. Who doesn’t realize he is himself responsible for it. While remaining in touch is good thing but sometimes it becomes annoying to have to deal With continuous incoming phone calls. For Example you are on a vacation and your boss Calls you to come back , how does that sound. Use of headphones for a longer time can also affect your ear-drums. Now a days you Can Download a lots of songs and use the headphones can affect the sensitivity of your ears in the long run of life There have been cases of cellphone blasts due to its excessive heating of it’s battery. This Can be fatal issue altough rare. In 2005 to 2010 the users of mobile phone users were nearly 327 million and in 2014 almost there was 3.5 billion users and now in 2017 the users are 4.8 billion and they will keep increasing according to the population and in 2020 approximate there will be 5.7 billion users….. Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models. Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas. Compouds In our tissues react with radiofrequency energy and this can be harmful for us. The only consistently recognized biological effect of radiofrequency energy is heating. The ability of microwave ovens to heat food is one example of this effect of radiofrequency energy. Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (ear, head, etc.). However, it is not sufficient to measurably increase body temperature, and there are no other clearly established effects on the body from radiofrequency energy. Moral of topic It is not bad to use cellphone for entertainment but not all the time. Use it for good , in result you will get good.. The negative side of phone is very bad don’t ever try to go in it The man who invented cellphone he did not made it for bad purpose only for Good Purpose….. People made it used for bad purpose….. It’s on us that how we use it Thank you We are very Grateful to you to co-operate with us
