Raspberry Pi OS is a Unix-like operating system based on the Debian Linux distribution for the Raspberry Pi family of compact single-board computers. Raspbian was developed independently in 2012, became the primary operating system for these boards since 2013, was originally optimized for the Raspberry Pi 1 and distributed by the Raspberry Pi Foundation.

Das U-Boot (subtitled "the Universal Boot Loader" and often shortened to U-Boot; see History for more about the name) is an open-source boot loader used in embedded devices to perform various low-level hardware initialization tasks and boot the device's operating system kernel.
When a system on a chip (SoC) enters suspend to RAM mode, in many cases, the processor is completely off while the RAM is put in self refresh mode. At resume, the boot ROM is executed again and many boot ROMs are able to detect that the SoC was in suspend to RAM and can resume by jumping directly to the kernel which then takes care of powering on again the peripherals which were off and ...
Note: The column MBR (Master Boot Record) refers to whether or not the boot loader can be stored in the first sector of a mass storage device. The column VBR (Volume Boot Record) refers to the ability of the boot loader to be stored in the first sector of any partition on a mass storage device.
Twister OS (Twister for short) is a 32-bit Operating System created by Pi Labs for the Raspberry Pi single board computer originally, with a x86_64 PC version released a few months later. [ 1 ] [ 2 ] Twister is meant to be a general-purpose OS that is familiar or nostalgic to users.
GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project.GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular ...
The first stage bootloader, which is a part of the MBR, is a 512-byte image containing the vendor-specific program code and a partition table. [6] As mentioned earlier in the introduction part, the first stage bootloader will find and load the second stage bootloader. [6] It does this by searching in the partition table for an active partition. [6]
The Platform Initialization Specification (PI Specification) is a specification published by the Unified EFI Forum that describes the internal interfaces between different parts of computer platform firmware. [1] This allows for more interoperability between firmware components from different sources.
