Can we see a life without our tiny portable devices? For most people, that seems impossible to imagine. Smartphones can be used for many other things other than for making calls or texting people. They have cameras, a Navigation System and most important of all, the ability to run applications. It behaves very much like a portable computer, where it is always connected to the internet either through a network carrier or through WIFI. Just like laptops or desktop computers, smartphones use operating systems to run software and applications. Apple, Microsoft, and Android are the biggest companies that manufacture smartphones in todays market. Smartphones can be used by people of all ages especially young adults, when it comes to social media and academics. Without a smartphone in your hand, life would just seem incomplete nowadays.
