Android tablet uses Linux operating system. Google purchased this software in 2005. Android tablet Firmware is a combination of hardware and software that results in better functioning of the tablet. Firmware is basically the programs or data are recorded on computer chips. Firmware is widely used in iPhone, iPad, and in the latest release the ginger pad, as well as in honeycomb models.

Android tablet firmware includes the data on chips called as ROMs that is Read Only Memory, PROMs that is Programmable Read Only Memory, EPROMs that is Erasable Programmable Read Only Memory. Read Only Memory means that the bits stored in the chip that can for no reason be customized once out of factory and it stores the data even devoid of power. Programmable Read Only Memory is a digital type of memory where every bit setting is done by either fuse or by anti-fuse. PROMs used to store the programs everlastingly. The difference between ROM and PROM is that, in PROM the programming is applied after the device is constructed. Erasable Programmable Read Only Memory in Android tablet means that the memory can be erased by the ultraviolet light exposure and then again reprogrammed.

Now the android tablet firmware has EEPROM that is Electrically Erasable Programmable Read Only Memory that permits overwriting when the higher range of voltage is applied on it so it can be serviced for regular updates. Later the Flash Memory replaced EEPROM, which now permits overwriting easily without using high voltage. Now days the ROM in smart phones is flash Memory.

custom android tablet firmware in PROM or EPROM is intended to be updated if essential. For example AirPort firmware, Bluetooth firmware, Mac Book firmware, Mac Book Air firmware, Mac Book Pro firmware, iMac firmware, Mac mini firmware, displays firmware etc...

iPod has a firmware. The updates for iPod including software, firmware or both incorporated in the iPod Software Updater. Not every product contains firmware update.

Sometimes it may ask that which version of firmware aka boot ROM one is having in the tablet. Below is given the way to find out how to decide the firmware version for one’s tablet.

Firstly open Tablet firmware; Open firmware is the common name of the firmware complying with IEEE Standard 1275-1994. Among all open firmware’s many features, it provides a tablet sovereign device interface for generally AGP or PCI cards. This regularly enables card expansion manufacturers to support easily with various diverse tablet designs devoid of supplying dissimilar firmware for everyone.
