Описание: What is Firmware, Typical Examples of Firmware Reasons for Updating Firmware Computer, Computer Concepts.

In electronic systems and computing firmware is a computer program that provides the low-level control for the device's specific hardware. Firmware can either provide a standardized operating environment for the device's more complex software or for less complex devices, act as the device's complete operating system, performing all control, monitoring and data manipulationfunctions.
Typical examples of devices containing firmware are embedded systems, consumer appliances, computers, computer peripherals, and others.A television remote control is an example of an
engineered product that contains firmware. The firmware monitors the buttons, controls the LEDs, and processes the button presses in order to send the data in a format the receiving device, in this case, a television set, can understand and process.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 lifetime.Common reasons for updating firmware include fixing bugs or adding features to the device.Ascher Opler coined the term "firmware" in a 1967 Datamation article. Originally it meant the contents of a writable control store containing
microcode that defined and implemented the computer's
instruction set and that could be reloaded to specialize or modify the instructions that the central processing unit (CPU) could execute.
