Little Powerful Devices:<\/em><\/strong> Did you know that the most popular app in the world is Facebook? It has over 4 BILLION downloads!<\/em> <\/figcaption><\/figure><\/div>\n\n\n\n

Smartphones not only allow people to connect over long\ndistances, but you can also play fun games, access the internet, and even buy\nthings with your phone! What makes these small, hand size devices work?\nSmartphones are small devices that send and receive radio signals, modern-day\ntwo-way radios! <\/p>\n\n\n\n

Let\u2019s\ndiscuss the most critical parts of a smartphone. There are hundreds of small\npieces that make a working smartphone. For our purposes, we will talk about\nfive important parts: the screen, memory, battery, antenna, and camera!<\/p>\n\n\n\n

What is the\nfirst part of a smartphone that you see? It\u2019s that big rectangular, black\nscreen! Once you hit the small home button, the black screen is replaced with a\ncolorful, bright screen. These screens are called displays. Displays come in\ntwo types, \u201cLCD\u201d and \u201cLED\u201d. LCD stands for Liquid Crystal Display. When an\nelectric current is passed, the crystals align so that can light can pass through.\nThe electric currents can either block light or allow it through. By blocking\nlight or letting it through, the electric currents create all the colors and\ndetails on an LCD screen. <\/p>\n\n\n\n

LED stands for Light-Emitting-Diodes. LED converts electrical current\ninto light, and the best part is that LED is energy efficient because it only\nlights up the parts of the screen with colors. These displays are harder to\nmake but use less energy from the battery.<\/p>\n\n\n\n

Pros and Cons:<\/strong> Although, LEDs are more energy\nefficient and their life span can last thousands of hours. However, LCDs have\ntheir own pros. LCDs produce very high brightness, and the images are extremely\nsharp, and are thinner and more compact, which is more convenient because they\ntake up less space.  <\/p>\n\n\n\n

Here are\ndescriptions of 4 other parts of a cell phone:<\/p>\n\n\n\n

Memory:<\/strong> No smartphone can function without\nthe memory. This stores all the data in your device so it can work fast and\naccurately. We will discuss about a specific type of memory called RAM, which\nis used in phones and computers, later on in the computer section. Basically,\nRAM speeds up the functions of cell phone devices, so you can download your\nvideo game or access the internet very quickly!<\/p>\n\n\n\n

Battery:<\/strong> Provides energy used to transmit\nradio signals, create visual displays, and run other components. It can store\nenergy in its special chemicals. Then, when your phone needs electrical\ncurrent, the battery provides the electricity. You can recharge the battery by\nplugging it into the electric grid.<\/p>\n\n\n\n

Antenna:<\/strong> Smartphones send and receive\ninformation. They can send your voice and your high score to a cell tower. And,\nthey can send your phone your friend\u2019s voice and new YouTube\u2122 videos. The\nantenna receives radio waves from the cell tower. Then, your phone translates\nthat information and displays it. Your voice and pictures can be translated\ninto memory packets and then sent to the cell phone tower by the antenna.  <\/p>\n\n\n\n

Camera:<\/strong> A camera cannot function without a lens and a sensor. The lens focuses the light on the sensor. The sensor converts the light into an electrical signal. This signal is then saved in the phone\u2019s memory. When you record a video, the sensor captures many pictures each second. When the pictures are played back quickly, it looks like things are moving. The earliest movies used this same idea! (But they aren\u2019t clearly as cool as your favorite slime video.)<\/p>\n\n\n\n

Shocking Fact:<\/strong> About three-quarters of U.S. adults\n(77%) say they own a smartphone. However, smartphones are more commonly owned\nby young adults with 92% of 18- to 29-year-olds say they own a smartphone. <\/p>\n\n\n\n
