A smartphone is a mobile device that has advanced features. It is not like a common mobile phone. It has the competence of a personal computer.
In reality, the mobile device industry does not have a defined meaning for Smart Phones. Smart Phones have an operating system that allows applications to be added to develop information processing or connections. A network operator or software developer can improve these applications.
Smart Phone uses many different operating systems. The most common are:
o Symbian Operating System from Symbian Ltd.
or Linux Operating System
o Palm operating system from Palm Source
or Windows Mobile from Microsoft
or RIM Blackberry Operating System
o Apple phone operating system
o Binary runtime environment for Wireless or BREW
BREW BEER
BREW (Binary Runtime Environment for Wireless) was created by Qualcomm. It is a software platform for application development. You can run and download small programs to share photos, play games, and send messages. The developer can simply port apps between all Qualcomm devices.
BREW is used between the application and the wireless device’s chip operating system. It helps a programmer to improve the applications without using code for the system interface. It can run on BREW RTOS. The BREW app can work on all BREW devices once the emulator is running.
BREW works faster due to its nature.
Linux
Another well-known operating system is LINUX. It uses the LINUX Kernel and is like UNIX. It is an example of free software and font development. It is easy to use, the source code can be modified and redistributed.
Libraries and utilities come from the GNU operating system. It is the basis of GNU/LINUX. The man behind the GNU project was Richard Stallman. It was created for a free software system that is fully UNIX compatible.
