UEFI, or Unified Extensible Firmware Interface, is a modern computer firmware interface that replaces the older BIOS standard.
It offers various benefits over BIOS, including increased security, compatibility with modern hardware, and broader support for operating systems.

What Is UEFI?
UEFI is a specification that defines a software interface between an operating system and platform firmware.
It’s designed to replace the Basic Input/Output System (BIOS) firmware interface present in all IBM PC-compatible personal computers.
UEFI provides for a faster boot process, more secure boot options, power management capabilities, and support for more modern hardware than the older BIOS.
What Are the Benefits of UEFI?
One of the main benefits of using UEFI is its ability to reduce the system’s boot time.
In addition, UEFI is more secure than BIOS, providing an enhanced level of security to protect against malicious activities.
It also provides a more advanced set of features and settings that can be used to customize the system’s performance and features.
How Does UEFI Compare to BIOS?
UEFI is the next generation of system firmware designed to replace the legacy BIOS system.
Compared to BIOS, UEFI provides faster boot times, improved security features, and enhanced system stability.
UEFI is designed to provide an intuitive user interface allowing users to access the system’s settings, navigate between different operating systems, and interact with the operating system using a graphical user interface.
Additionally, UEFI supports advanced configuration options, such as disk encryption, virtualization, and boot order priority.
Secure Boot Feature
Secure boot ensures that only trusted, signed software can boot the operating system.
This prevents malicious software from running and compromising the system’s security.
The Secure Boot feature is built on a public-key infrastructure that is used to authenticate the software before it’s allowed to boot.
This feature also ensures that the firmware itself can’t be tampered with, as it is cryptographically signed by the manufacturer.
Summary
In summary, UEFI is a powerful system that offers great flexibility and control to computer users.
It replaces the old BIOS system, providing faster boot times and a more secure environment.
UEFI also offers a wide range of features and options, including support for the latest storage devices, graphics, and networking technologies, as well as enabling more powerful system security and configuration settings.
All of these benefits make UEFI an invaluable tool for modern computers.
