UEFI (Unified Extensible Firmware Interface) is a software interface specification that replaces the traditional BIOS in modern computers. It serves to load operating systems and configure computer hardware.
UEFI provides more advanced capabilities compared to traditional BIOS. Some of its main advantages include:
- Improved boot capabilities: UEFI can boot operating systems with advanced file systems such as GPT (GUID Partition Table), which supports drives larger than 2 terabytes or larger.
- Graphics interface: UEFI provides the ability to use the graphical interface when configuring the computer. This makes the setup process more convenient and accessible to users.
- Advanced network capabilities: UEFI supports network protocols that allow you to download operating systems and updates over the network directly from web servers.
- More advanced hardware settings: UEFI allows you to more configure system parameters such as processor speed, voltage, memory and others.
- Support for additional features and devices: UEFI provides advanced support for new technologies such as Secure Boot (secure boot), TPM (Trusted Platform Module) and embedded peripherals.
What are the main differences between UEFI and BIOS?
The main differences between UEFI (Unified Extensible Firmware Interface) and BIOS (Basic Input/Output System) are:
- Operating systems boot: BIOS can only boot operating systems from drives that use standard MBR (Master Boot Record) markup. While UEFI supports more advanced GPT (GUID Partition Table) disk markup, which allows you to boot operating systems from disks larger than 2 terabytes or more.
- User Interface: The BIOS usually has a text interface with a limited set of options and menus available for customization. While UEFI supports a GUI with more user-friendly and intuitive customization options.
- Security: UEFI provides advanced security capabilities such as Secure Boot, which checks the digital signatures of the downloadable software to prevent malicious code from being downloaded. The BIOS does not have such built-in security mechanisms.
- Hardware Setup: UEFI provides more extensive hardware setup options, including detailed parameters of the processor, memory, I/O ports, and other components. The BIOS has less advanced customization options.
- Extensibility and advanced features: UEFI is a more flexible and extensible interface that supports additional features such as network boot protocol (PXE), advanced storage devices, embedded devices, etc. The BIOS has limited functionality.
- Initialization start: The BIOS starts when the computer is turned on and performs the POST (Power-On Self Test) process, after which it transfers control to the operating system. UEFI performs a more complex initialization process, which may involve recognizing and configuring hardware prior to operating system boot.
UEFI is a more modern and advanced standard compared to BIOS and provides more options for system configuration, security and extensibility.
