00:00Do you know how a computer is turned on? The first thing that works is ROM, i.e. read-only memory.
00:05BIOS is stored in ROM. As soon as you press the power button, the ROM gets activated immediately.
00:10Starts the system, then does the ROM post (power on self test) and checks that the RAM
00:15Is it correct or not? Is the keyboard connected or not?
00:19If there is any problem, an error message or beep sound appears, after which the ROM scans the device and
00:24Starts loading the operating system. Once the operating system is loaded, it controls the RAM and processor.
00:29In simple language, without ROM the system will not be able to operate, such technology is available.
