​KembaraXtra-Computer Terms – boot block:
A boot block is a specific section of a storage device, such as a disk, that contains essential information needed to start a computer system. This section typically includes the operating system loader along with basic instructions required during the startup process.
When a computer is powered on, it reads the boot block to begin loading the operating system into memory. Without this information, the system would not be able to initialize properly or proceed with the boot process.
