I am sorry for asking such a stupid question but if bios is stored in the rom then why can we change  it as we want ? Also when we update our bios, then aren't we writing on it ? It is very slow slow to write on rom as said by my school textbook, so why can I update it so fast ? Sorry once again.

The How To Geek article linked below should help clear this up for you. TL;DR: the BIOS code is stored in EEPROM, not just regular ROM.
