Let's talk about this inside
Channawut i heard that it's your first day of school, how was it?
This just family business , i am actually a software developer?
ommmm you're talking to a right person. I'm graduated it degree
oh really and why are you selling tea?
Everything went well but I don't understand about the operating system that i had been taught today
Operation system(OS) provides interfaces between user and computer , manage software and hardware
It' also control the hardware and check the system
It's like commenting the computer
Channawut was back home from school, he felt tired so he went to buy tea ( chaichad ) . He saw the owner and ordered the tea.
There is like layer of operating system. the first one is user programs(applications) layer or us who is commenting the computer. The next one is operating system even Bios and then hardware.
I heard about bios but i don't know what is it?
While waiting for the tea , he talks about what he had learned in school.
If it's ok there will be 1 beep and if isn't there will be lots of beep sounds
Yeah Bios is a basic system that control the motherboard as well as the hardwares that is joined with motherboard and also post(power on self test)
After pressing the power button the bios will check or communicate with other hardware if is it ok and ready to use and the power is enough or not
