A smartphone is a cellular telephone with an integrated computer and other features not originally associated with telephones, such as an operating system, web browsing and the ability to run software applications. ... HTC released its Dream smartphone a year later, which was the first to include Google's Android OS.Briefly, a smartphone is a device that lets you make telephone calls but also adds in additional features such as the ability to send and receive e-mail, edit documents, download apps, and more. Popular operating systems for smartphones are BlackBerry OS, Windows Mobile, and Android.A smartphone is a mobile phone that can do more than other phones.[1] They work as a computer but are mobile devices small enough to fit in a user's hand.
Uses include:
Sending and receiving emails, text, photographs and multimedia messages
Registering contacts
calculator, currency, alarm, etc. functions
Browsing the Internet using a mobile browser
Playing games
Video chat
point of sale terminal when paying for goods or services
barcode scanning
creating high quality photographs or video
Determining user's exact location utilizing GPS (global positioning system) satellites
Another way to think of them is that they are PDAs that can make voice calls like any other mobile phone. Older phones also used computer technology, but lacked many of the parts of a computer that were too big to fit into a phone. Modern phone makers have been able to use smaller parts. Most smartphones are also GPS receivers and digital cameras.
Because smartphones are small computers, they run an operating system that is often common between devices to ensure compatibility. The majority of smartphones run on Apple iOS or Google Android but others use Windows Phone or BlackBerry OS.[2] Most can do multitasking, running more than one program which helps the user do things quicker and easier. Users can get more programs, called mobile apps, from the manufacturer's app store, such as the Apple App Store and Google Play which can help them complete special tasks.
Data communication has become faster. Smart phones can send and receive data much faster than older phones. The industry uses different standards to label the data transmission rates. 2G was introduced in 1991. 2G means 2nd Generation. 2G phones transmit data at about the same speed as a 56kbit/s (kilobits per second) dial-up modem would get.
3G was introduced in 2002. Depending on where they are, 3G phones vary in speed between about 200kbit/s to 14Mbit/s (megabits per second). This is comparable to a DSL or low end cable modem speed. Most smart phones use 3G technology to make them fast enough to practically use internet and other data features. Faster 4G networks operate in many places, with speeds estimated as fast as 100Mbit/s to 1Gbit/s (gigabit per second). This would be as fast as some computer networks that use ethernet. Many smart phones introduced after 2010 use 4G technology including the later, even faster version of 4G known as LTE. 5G is planned.
