Firmware it is usually a low-level software necessary for hardware to work with software, typically located in read-only memory (ROM), serving as a mediator between the actual microprocessors and the operating system and software a user runs. Itβs a type of software that lives on hardware and contains specific instruction sets that allow the hardware to interface with higher-level software like the operating system.
You find firmware in a variety of devices such as TV Remote Controls, computer hard drives, Keyboard, robots, routers and many more. While the firmware in TV Remote reads the input from the keys pressed and activates the Infrared LED accordingly, the firmware in a computer hard drive acts a little bit differently, typical example of firmware in computer is BIOS.
Software, on the other hand, is a more general term that refers to a program or a set of programs that are used to perform a specific task or tasks on a computer. Software can be installed and uninstalled on a computer, and it is typically stored on a hard drive or other storage medium. Examples of software include word processors, web browsers, video games, engine controls software and operating systems.
In summary, firmware is a type of software that is permanently stored in a hardware device and controls its operation, while software is a more general term that refers to a program or set of programs that perform specific tasks on a computer and can be installed, updated, or uninstalled as needed.

Updating firmware typically involves downloading a new firmware image file, and then using a specialized tool to load the new firmware onto the device's memory. This process can be more complex than updating software, and can involve additional steps such as putting the device into a special "firmware update" mode, or connecting the device to a computer via a USB cable.
Updating software is generally a simpler process, and can be done using an automated update process or by downloading and running an installer program. In either case, it's important to follow the instructions provided by the software developer or device manufacturer carefully, to avoid any issues with the update process.
