rendszerindítási

Rendszerindítási, a Hungarian term, translates to "booting" or "system startup" in English. It refers to the process a computer or electronic device undergoes when it is turned on. This process begins when the power button is pressed and ends when the operating system is fully loaded and ready for user interaction.

The system startup involves several stages. Initially, the hardware components are initialized and tested through a Power-On Self-Test (POST). This diagnostic check ensures that essential hardware like the CPU, memory, and graphics card are functioning correctly. Following a successful POST, the system's firmware, typically the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface), takes over.

The firmware's primary role is to locate and load the bootloader, a small program responsible for initiating the operating system. The bootloader then finds the operating system kernel on the storage device (such as a hard drive or SSD) and loads it into memory. Once the kernel is loaded, it begins to initialize the operating system's core services, drivers, and user interface. This sequence of events leads to the device becoming fully operational. The term "rendszerindítási" encompasses this entire complex, yet critical, sequence of operations.
