The evolution of technology is a phenomenon that cannot be denied. New gadgets seem to appear overnight and it is now customary for most people to own a smart phone, tablet or at least laptop. And even if these devices have become so popular in the past years, few individuals know how complex a cell phone actually is. As a matter of fact, these objects are some of the most intricate as far as technology is concerned: they are able to process millions of orders per second, only to compress and decompress voice calls, not to mention their other features. Given their high performance, there is a great ensemble of components, both software and hardware, making up these gadgets. Here is a closer look “inside” a cell phone, which will help you understand how such a device really works.

The hardware architecture

As same as computers and laptops, mobile phones also have a hardware architecture aimed to support users’ activity. Here, the main part is represented by the application processor, a circuit board that works as the device’s brain. This means that it executes end-user’s commands through an intricate software system (sometimes known as OS), transforming them into actions per se. besides that, there is another type of processor influencing the phone’s performance the modem or baseband processor. This one has its own operating system, inaccessible to the user, by the means of which the gadget can respond to digital activities, such as reception and transmission of data contents like audio and video data. In addition to these two major components of a mobile phone, there are also many other peripheral parts necessary for a qualitative interaction with the end user. While some of these are integrated, others can be purchased and added separately, such as LG accessories or others, depending on the brand. The liquid crystal display (LCD screen), headphones, microphone, speakers or battery are only some of the most popular components people are aware of. It is important that users know these parts can be bought and exchanged at any time, since they are easily to replace.

Operating systems

Originally, when they were first launched, each mobile phone company had its own user interface. This could be considered a closed operating system, given the fact that it was not transferable and could barely be configurated or customized. Needless to say, it also had a minimal variety of application, which were mostly basic: games, calculator or conversion tools. Fortunately, the evolution of technology enabled the development of more performing pieces of software and applications. At the moment, the specialized market is divided into three main operating systems, depending on the manufacturing company: Android, Windows and iOS. However, nowadays even the most basic smart phone has a web browser, email app and a dedicated store where users can get whatever application they want. While this store generally offers free products one can get, some other apps have to be paid for.
