Smartphones: Mobile Phone Essay

Smart phones “Excellent Innovation”
Every day computing needs is shifting from laptop and desktop to smart phones and tablets. A Smartphone is a mobile phone with Internet access for email, short messaging service, multimedia messaging service the capability to take record photos and videos, GPS hardware and software built into the phone, the ability to read and edit a variety of files in different formats, and Wi-Fi and Bluetooth capabilities. So basically smart phones are part of every one’s life without smart phones people can’t live. Smart phones are like small computer and we can work easily smart phones perform different kind of operation like internet surfing, business software, education purpose so as per my point of view smart phones are valuable invention.
Operating system (OS) is the main program to control and perform different kind of operations; the OS provides a set of services to users by using the hardware resources of processors and organizes. Operating system supports all kind of software which is important for office and educational work. The five main operating systems in the world’s market are Google’s Android, Apple’s iPhone OS (iOS 5-6), BlackBerry OS, Microsoft’s Windows Mobile/Windows Phone for Windows 7), and Symbian OS and major smart phone companies improved their systems day by day. Those companies launch different types of smart phones like Samsung Galaxy, Apple Iphone-5, and Nokia Lumia and Blackberry bold etc.
The OS is an open source, whose source code is accessible to all people, or proprietary or closed source. Apple’s iOS gives extra exclusivity to mobile phone manufacturers but offers limited smartphone functionality. The iPhone was notable for its use of a large touch screen for direct finger input as its main means of interaction, instead of a stylus, keyboard, and/or keypad as typical for smart phones at the time. It initially lacked the capability to install native applications, meaning some did not regard it as a Smartphone an open source OS such as Google’s Android is more receptive to the introduction of smartphone applications and services by wireless providers and network operators. Open source software also encourages innovation because it gives third-party developers access to the source code. Smart phone companies’ operating system is also secured so they protect from identity theft and other issues.
Most smartphones have Bluetooth and Wi-Fi connectivity and GPS. Bluetooth technology allows users to transfer data from one phone to other phone and computers. Wi-Fi helps users to connect internet on their phones. Pocket Internet Explorer, Google chrome and Mozilla browser are examples of smartphone browsers while users can view pictures, videos and other important applications on their phones. A camera of varying resolution for capturing images and videos is a standard smartphone feature. The standard smartphone also carries software for email, MMS, word processing, spreadsheet, instant messaging, and PIM software such as calendar and phonebook (188). High-end smartphones have better feature sets.
The early smartphones used 2G mobile networks that provided voice calls and SMS messaging and data transfer speeds of about 473Kb. Later models and perhaps the most widely used are 3G and 4G networks that offer data transfer speeds up to 2-4Mb. Access to new 4G network that has the fastest data transfer speed is currently limited because of the slow implementation of the technology. In future generation of smart phones they improve OS and mobile chips which allow advance functions and faster rate of data transfer. In 4G and 3GLTE phones there is some functions like voice identification and by this application users have to just speak and phone perform those operation so it is very advance techniques.
New or emerging smartphone technologies and applications for smartphones are augmented reality, voice-to-text and text-to-voice, generation of user-generated text and other
