Imagine that there is a car crash. Glass shards have penetrated the area. The scene is unsafe. You were the one in that car. Would you call 100? And if you could how? This is where cell-phones come in handy. In today's contemporary society, cell-phones are a necessity--however, they can also be a burden. In the following paragraphs, I will show how the effectiveness of phones are comparatively demonstrated against the many disadvantages presented with the introduction of these devices. Introduction :

Cell phone Definition: A  cellular phone is a device which can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile network operator. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared,Bluetooth), business applications, gaming and photography.

The first cell phone: 

The first cell phone The first cell phone was created in 1973 by Martin Cooper of Motorola, but cell phones didn’t hit stores until 1984.

The First Telephone : 

The First Telephone The first telephone was invented in 1876 by Alexander Graham Bell.

Before the cell phone: 

Before the cell phone The invention of the cell phone came from the creation of the radio. Police radios and the mobile car phone gave way to the mobile phone.

History Of Cellphones The history of the cell phone starts with a block phone that did not have a color screen. It had a universal green back light and black writing. It then evolved to color screens and camera phones. Now, you can get a cell phone that can do almost anything that you can possible think of.

Cell Phone Features All mobile phones have a number of features in common, but manufacturers also try to differentiate their own products by implementing additional functions to make them more attractive to consumers. This has led to great innovation in mobile phone development over the past 20 years . The common components found on all phones are : Software and applications : The most commonly used data application on mobile phones is SMS text messaging. The first SMS text message was sent from a computer to a mobile phone in 1992 in the UK, while the first person-to-person SMS from phone to phone was sent in Finland in 1993.

PowerPoint Presentation: 

Cell Phone Features Power supply : Mobile phones generally obtain power from rechargeable batteries. In 2009, the first wireless charger was released for consumer use. SIM Card : GSM mobile phones require a small microchip called a Subscriber Identity Module or SIM Card, to function. The SIM card allows­­­ users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device.

PowerPoint Presentation: 

Cell Phone Features Display : Mobile phones have a display device, some of which are also touch screens. The screen size varies greatly by model and is usually specified either as width and height in pixels or the diagonal measured in inches. Central processing unit : Mobile phones have central processing units (CPUs), similar to those in computers, but optimized to operate in low power environments.

IN GENERAL Advantages of mobile phones Mobile phones are used for a variety of purposes, including keeping in touch with family members, conducting business, and having access to a telephone in the event of an emergency. Multiple SIM cards may also be used to take advantage of the benefits of different calling plans—a particular plan might provide cheaper local calls, long-distance calls, international calls, or roaming.

Advantages of mobile phones By the media In 1998, one of the first examples of selling media content through the mobile phone was the sale of ringtones by Radiolinja in Finland. Soon afterwards, other media content appeared such as news, video games, jokes, horoscopes, TV content and advertising Sharing : In some parts of the world, mobile phone sharing is common. It is prevalent in urban India, as families and groups of friends often share one or more mobiles among their members.

Advantages of mobile phones Whilst driving Mobile phone use while driving is common but controversial. Being distracted while operating a motor vehicle has been shown to increase the risk of accident. Because of this, many jurisdictions prohibit the use of mobile phones while driving.

PowerPoint Presentation: 

Advantages of mobile phones In school: Some schools limit or restrict the use of mobile phones. Schools set restrictions on the use of mobile phones because of the use of cell phones for cheating on tests, harassment to the schools security, distractions to the students, and facilitating gossip and other social activity in school . Tracking and privacy : Mobile phones are also commonly used to collect location data. While the phone is turned on, the geographical location of a mobile phone can be determined easily (whether it is being used or not), using a technique.

PowerPoint Presentation: 

Disadvantages of mobile phones The cost, they are more expensive than normal phones They are fragile so you may break them You may have no credit when u need it most Can distract you while driving They can damage your ears There are both pros and cons of having a mobile phone although in this day and age, I believe that mobile phones are a must, especially if you are an adult.

PowerPoint Presentation: 

Disadvantages of mobile phones Health Effects : The effect mobile phone radiation has on human health is the subject of recent interest and study, as a result of the enormous increase in mobile phone usage throughout the world. Mobile phones use electromagnetic radiation in the microwave range, which some believe may be harmful to human health . On 31 May 2011, the World Health Organization confirmed that mobile phone use may represent a long-term health risk, classifying mobile phone radiation as a "carcinogenic hazard" and "possibly carcinogenic to humans" after a team of scientists reviewed peer-review studies on cell phone safety.One study of past cell phone use cited in the report showed a "40% increased risk for gliomas (brain cancer) in the highest category of heavy users (reported average: 30 minutes per day over a 10‐year period)."

The Future of Cell Phones Today's mobile phones can already send e-mail, browse the Web, and keep you in touch with friends and colleagues via voice or text message. Tomorrow's handsets will add even more to the menu, morphing (as needed) into always-connected portable game consoles, full-featured TVs, and credit cards.

Problem Solution: 

Problem Solution Cell phones used to be big and bulky. Now cell phones are so convenient that they can fit in my pocket.

After the cell phone new technology: 

After the cell phone new technology The most desirable phone right now is the Apple iPhone . The iPhone is a phone, an iPod, has internet, GPS, is on the 3G network, and much more.

After cell phones: 

After cell phones Cell phones just keep advancing and in the future will be able to do almost anything.

PowerPoint Presentation: 

As shown, there are many advantages to having a cell-phone. The disadvantages are also staggering. Overall, the decision to have one or not is yours, the consumers. Dependant on your needs, you may want a cell-phone. Many risks may ensue. In fact, maybe the reason you got into a car crash is because you were on a cell-phone.
