Smart phones/Small Computer.

mobile phone1 (also known as a wireless phonecell phone, or cellular telephone) is a little portable radio telephone,(Apple iPhone1, HTC1, Nokia1, Samsung these are the major smart phone1.

Around the world we find many types of mobile, now the trend has changed. Every body now love to have a smart phone1. The latest mobile phones1 are commonly referred to as smart phones1. These phones can be used for email, browsing the internet, playing music and games, and many other functions that computers can perform. This is because they basically are small computers. 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 make computer parts small enough to fit inside a phone. 

Advancements have also been made in the field of data communication. 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 56kbps (kilabits per second) dial-up modem would get. 3G was introduced in 2002. 3G phones vary in speed, but range from about 200kbps to 14mbps (megabits per second). This is comparable to a DSL or low end Cable Modem's speed. Most smart phones use 3G technology because 2G is not fast enough to practically use e-mail, internet, and other data features. A new Generation of technology is being introduced now called 4G. 4G speeds are estimated to be as fast as 100mbps to 1gbps (gigabit per second). This would be as fast as some computer networks that use ethernet. The newest smart phones use 4G technology.
