Tipos de BIOS

  • ROM ( Read Only Memory): This type of BIOS can be recorded only when the chip is made. When defined as non-volatile memory, the information or data contained therein is not susceptible to alteration.
  • EPFROM (Erasable Progammable Read-Only Memory) and EEPROM (Electrically Erasable Programmable Read-Only Memory): Memories of these types are rewritable and can be programmed with electrical impulses. The content it maintains is removable through exposure to ultraviolet lights.
  • FLASH BIOS: This flash memory is one of the most used today. This kind of memory is included among the most volatile category. It has the ability to be re-recorded, without the need for a deletion device. Normally, it is possible to update it permanently and very easily.
