Q

is a sequence of events that begins when a system is powered on and ends once the OS kernel is loaded into memory space and begins executing.

A

boot process

41
Q

is a set of instructions embedded onto a ROM, PROM, or EEPROM that tells the device how to communicate with other hardware and software.

A

Firmware

42
Q

which creates cylinders, tracks, and sectors (commonly 512bytes in size) on the platters

A

43
Q

groups consecutive sectors together and prepare a hard drive for storing a file system.

47
Q

occurs when a computer is initially powered on. The BIOS executes a POST (Power-On Self-Test)to initialize and test hardware components. The POST uses beep codes and/or light indicators for error notification.

49
Q

initialize and test hardware components. This uses beep codes and/or light indicators for error notification.

A

POST

50
Q

contains a partition table identifying the location of all created partitions. Creation of additional partitions updates the existing partition table. it resides at the first physical sector of the drive (sector 0) and is not part of any partition.

56
Q

Is an improved method of booting due to its highly secure way of carrying out the boot process, checking the integrity of drivers and OS boot loaders that use verification and initialization of digitally signed code.

A

UEFI

57
