Explain the concept of UEFI (Unified Extensible Firmware Interface) and how it differs from traditional BIOS.
1) UEFI(Unified Extensible Firmware Interface), is a modern firmware interface that serves as the bridge between the computer's hardware components and the operating system. It provides a more advanced and flexible environment for firmware operations compared to the traditional BIOS.
2) UEFI uses a 32-bit or 64-bit architecture, supports the GUID Partition Table (GPT) for larger drive capacities, offers both Legacy and UEFI boot modes, and includes features like Secure Boot for enhanced system security. UEFI also provides a graphical user interface (GUI) for easier configuration and settings management.
3) The traditional BIOS(Basic Input/Output System) is the firmware interface that has been the standard in computing for several decades. It operates in 16-bit mode and serves as the intermediary layer between the computer's hardware and the operating system.
4) BIOS uses the Master Boot Record (MBR) method for booting, which has limitations in terms of partition size and boot options. It typically uses Legacy Boot mode and lacks advanced features like a graphical user interface. BIOS environments are text-based and relatively simple, with limited user interaction.
