Kiinteäohjelmisto

Kiinteäohjelmisto, often referred to as firmware in English, is a type of software that is permanently programmed into a hardware device. Unlike application software that can be easily changed or updated by the user, kiinteäohjelmisto is embedded directly into the device's read-only memory (ROM) or flash memory. This means it is not typically user-modifiable and serves to control the fundamental operations of the hardware.

The primary purpose of kiinteäohjelmisto is to provide low-level control for the hardware components of a device. It acts as an intermediary between the hardware and any higher-level software, such as an operating system or application. This allows the device to function correctly from the moment it is powered on. Examples of devices that utilize kiinteäohjelmisto include routers, printers, digital cameras, solid-state drives, and many embedded systems.

While kiinteäohjelmisto is designed to be permanent, it can sometimes be updated. These updates, often referred to as firmware upgrades, can introduce new features, fix bugs, or improve performance. However, updating kiinteäohjelmisto is a more involved process than updating regular software and carries a risk of rendering the device inoperable if not performed correctly. The term "kiinteäohjelmisto" emphasizes the fixed and permanent nature of this essential software component within electronic devices.
