Study Notes
ROM vs. RAM
- ROM (Read-Only Memory) is non-volatile, retaining data during power loss, while RAM (Random Access Memory) is volatile and loses data when power is off.
- ROM is used to store permanent data, whereas RAM is used for temporary data storage.
Functions of BIOS
- BIOS (Basic Input/Output System) performs the Power-On Self Test (POST) to ensure the system is functioning correctly upon startup.
- BIOS checks all connected devices to the computer to confirm their presence and functionality.
- It initializes hardware components essential for booting the operating system.
BIOS Settings Storage
- BIOS settings are stored in the CMOS (Complementary Metal-Oxide-Semiconductor) chip, allowing configurations to persist even when the computer is powered off.
Traditional BIOS vs UEFI
- UEFI (Unified Extensible Firmware Interface) offers better compatibility with modern hardware compared to traditional BIOS.
- UEFI is now the default firmware interface for new computer systems.
- Traditional BIOS does not provide the same level of compatibility with newer hardware as UEFI does.
- UEFI is designed to establish itself as the new standard for BIOS technology moving forward.
