What is UEFI and how does it differ from traditional BIOS?
UEFI (Unified Extensible Firmware Interface) is a type of firmware that replaces traditional BIOS (Basic Input/Output System) in modern computers. While BIOS is limited to 16-bit processing and 1MB of address space, UEFI is 32-bit or 64-bit and has a much larger address space, allowing for more features and better performance. UEFI also provides a more intuitive and user-friendly interface, making it easier to configure and troubleshoot your system.
In contrast to BIOS, UEFI is more secure, thanks to its ability to validate the authenticity of the operating system and prevent malware from running at boot time. UEFI also supports advanced features like Secure Boot, which ensures that only authorized operating systems can boot on the system. Additionally, UEFI provides better support for modern hardware, such as USB devices and high-capacity storage drives.
What is GPT and how does it compare to MBR?
GPT (GUID Partition Table) is a partitioning scheme used to organize data on a hard drive. It is an alternative to the older MBR (Master Boot Record) scheme, which has limitations when it comes to disk size and partitioning. GPT is more modern and flexible, allowing for larger disk sizes (up to 18 exabytes) and more partitions (up to 128). GPT is also more reliable, as it stores multiple copies of the partition table, making it easier to recover from data corruption.
GPT is particularly useful for modern systems, as it supports advanced features like UEFI firmware and 64-bit operating systems. In contrast, MBR is limited to 32-bit systems and has a maximum disk size of 2TB. GPT is also more secure, as it includes built-in support for partition encryption and digital signatures. Overall, GPT is a more powerful and flexible partitioning scheme than MBR, making it a better choice for modern computers.
