This indicates this initializes the device and typically looks for connected disk drives or cartridges during initialization and either attempts to load the real operating system (Windows is an example) or load a game in the case of game consoles. And when it’s off, only ROM will memorize data and software code! A BIOS ROM currently has these system instructions, and never forgets it! The system code is used each time the machine is turned on to load. But, when the device is turned off, RAM does ‘forget’ its stuff. The machine has another built-in memory, too: RAM. This file is built-in, unlike CD ROMs and cartridges, which cannot be deleted from the machine. Most computers have ROM (Read Only Memory) or Flash ROM BIOS in them.
BIOS-this is the Simple Input / Output Device shortcut-B, I, O, S-that’s where the name comes from!
