käynnistyslataajien

Käynnistyslataaja, or bootloader in English, is a special program that runs when a computer or device starts up. Its primary function is to load the operating system into the computer's memory. When a device is powered on, it first executes the firmware, which then locates and runs the bootloader. The bootloader's job is to initialize essential hardware components and then find the operating system kernel file. Once located, it loads the kernel into RAM and passes control to it. This allows the operating system to take over and complete the startup process. Different operating systems and hardware architectures use various types of bootloaders, such as GRUB for Linux, the Windows Boot Manager for Windows, and UEFI firmware for modern systems. The bootloader can also offer options to the user, like selecting which operating system to boot if multiple are installed. In essence, the käynnistyslataaja acts as the crucial intermediary between the hardware and the operating system, enabling the device to become functional.
