Chapter 9: Implementing Mass Storage Flashcards
What is partitioning
sub dividing the hard drive into 1 or more physical units called partitions
What is formatting
Installs a file system onto the drive which organizes the drives partitions in such a way an OS can store files and folders onto the drive
What is the smallest unit on a hard drive
The sector
What are the 2 smallest parts of a SSD
the page and then the block
What chip on the HDD controls accessing the correct information
Drive controller
What are the 3 partitioning methods
MBR, windows proprietary, and GPT
what makes something a basic disk
when the partitioning scheme uses MBR or GPT
What makes something a dynamic disk
It uses the dynamic partitioning scheme
What does the first sector of a MBR drive contain and what is it called
“master boot record” contains information on the installed operating systems, the partitioning table which describes the number and size of partitions on the disk
What is the cradle to grave operation to load an OS
BIOS –> master boot record –> partitioning table –> Partition –> partition boot sector –> OS
how many partitions are supported for MBR
4 because the the limit of information that can go in the Master boot record sector THIS ONLY APPLIES TO PRIMARY PARTITIONS EXTENDED PARTITIONS OVERCOME THIS LIMITATION
What is a primary partition
A primary partition is a partition that is assigned a drive letter and can hold an OS. Side note an active partition is the one that is actively hosting the OS and there can only be one
What does GRUB stand for
Grand Unified Boot Manager this manages your OS’s that are currently installed and which you want to boot on bootup
What is a logical drive
Drives that are apart of an extended partition that you further partition to include drive letters
What is unique about dynamic disks
can create as many volumes as you want (not restricted to just 4), and you can use fancy storage methods like raid spanned mirrored and stripped volumes
