Final answer:
Firmware is the software installed on read-only memory in devices like printers and is responsible for the device's control and operation. It is designed not to require frequent updates but can be updated to fix bugs or add features. This contrasts with system software, application software, and middleware.
Step-by-step explanation:
The software that is installed often in special, read-only memory in devices like printers or communication devices is called firmware. Firmware acts as the operating system for such devices, providing the low-level control for the device’s specific hardware. Unlike system software that runs on computers and application software that provides users with specific tools and features, firmware resides in non-volatile memory devices and typically does not need to be changed or updated frequently. It's sometimes updated to fix bugs or add new features, in a process known as flashing. Middleware, on the other hand, is software that acts as a bridge between application software and system software or hardware components of a computer.
