COMPUTER FUNDAMENTALS

Detailed explanation-1: -In computing, BIOS (/ˈbaɪɒs, -oʊs/, BY-oss, -⁠ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

Detailed explanation-2: -The boot ROM is a type of ROM that is used for booting a computer system. There are two types: a mask boot ROM that cannot be changed afterwards and a boot EEPROM, which can contain an UEFI implementation.

Detailed explanation-3: -Electrically-erasable programmable ROM (EEPROM)-Often used in older computer chips and to control BIOS, EEPROM can be erased and reprogrammed several times while enabling the erase and writing of only one location at a time.

Detailed explanation-4: -A computer’s basic input/output system (BIOS) is a program that’s stored in nonvolatile memory such as read-only memory (ROM) or flash memory, making it firmware.

Detailed explanation-5: -ROM, Firmware, and BIOS Read Only Memory (ROM) is found in a microchip within the motherboard, and it cannot be easily altered. This is a type of non-volatile memory that is used to run firmware, or the BIOS, on a personal computer.
