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. 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.
