Firmware is a type of software that is embedded in hardware devices, such as iPhones. It controls the low-level operations of the device and provides the interface between the hardware and the operating system. Firmware updates are released regularly to fix bugs, improve performance, and add new features to the device.
It is important to keep your iPhone’s firmware up to date to ensure that your device is running at its best. Outdated firmware can lead to security vulnerabilities, performance issues, and other problems.
