Hello Experts,

i am just curious to know about firmware.

Siemens keeps on realeasing new products with updating a firmware every time once it is available to us.


i know about software,hardware but what is this firmware?  

Hi,
 You only know that the firmware is a special software for the equipments, the firmware is depend on each version of product.
 Every years Siemens update new technology, thus the hardware & firmware has be change too. 
  But sometime we still can use the old firmware for new product. ( eg. Micro master drives ..)


I found this information from internete. This share will helps to more understand.

In electronic systems and computing, firmware is the combination of read-only memory and program code and data stored in it. Typical examples of devices containing firmware are embedded systems, computers, computer peripherals, mobile phones, and digital cameras . The firmware contained in these devices provides the control program for the device. Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory. Changing the firmware of a device may rarely or never be done during its economic lifetime; some firmware memory devices are permanently installed and cannot be changed after manufacture. Common reasons for updating firmware include fixing bugs or adding features to the device. This may require physically changing ROM integrated circuits, or reprogramming flash memory with a special procedure. Firmware such as the ROM BIOS of a personal computer may contain only elementary basic functions of a device and may only provide services to higher-level software. Firmware such as the program of an embedded system may be the only program that will run on the system and provide all of its functions.
