  1. 1. Android and Android Phones

Different versions have been released andperfected since the original release in 2008.
  3. 3. Founded by Andy Rubin and Rich Minor of Palo Altoteamed up with Chris White and Nick Spears who workedtogether to develop the software and associatedtechnology to produce the highly efficient Androidoperating system. While there have been many differentversions of this technology, it is important to realize thateach version of the operating system has helped todevelop the most efficient operating system that is bestfor the customer of that point in time.
  4. 4. For example, smart phone technology has advancedso much in the past four years alone, the operatingsystem of Android needed to advance as well in orderto meet the needs of customers and to be able tocompete with other operating systems on the marketsuch as that of the Apple iPhone or theBlackberry.

Android OS NamesWhile it was only released about four years ago, theAndroid operating system has gone through severaldifferent names and versions before settling on theAndroid name that is commonly known today. Previousnames include Cupcake, Honeycomb and Jelly Bean amongmany others. The Android company worked on developingthis product since the companys inception in 2003 in PaloAlto, California.
  6. 6. ll with backgrounds in IT and web development as well assoftware technology, the four men worked on thesoftware and continued to do so after the company wasacquired by Google in 2005. Since Google had the financialmeans as well as the man power to develop the Androidsoftware technology to the maximum extent, this was agreat move for the Android company and led to substantialadvances in the Android operating system and theproducts release in 2008.

These alternative methods are still available withthe latest Android.External storageMost Android devices include microSD slot and can readmicroSD cards formatted with FAT32, Ext3 or Ext4 file system. To allow use of high-capacity storagemedia such asUSB flash drives and USB HDDs, many Android tablets also include USB A receptacle.Storage formatted with FAT32 is handled by Linux Kernel VFAT driver, while 3rd party solutions arerequired to handle other popular file systems such as NTFS, HFS Plus and exFAT.
