Chapter 9 - Implementing Mass Storage Flashcards
Partitioning hard drives
defining the locations of storage on a hard drive
Swap partition is in which OS system?
Are in linux and manifest as folders
A partition is what?
A logical electronic device readable by an operating system.
MBR partition stands for what?
Master boot record(MBR) partitioning, oldest type of partitioning, tells the system where to find the OS. still used today.
LBA 0
The location on the drive where the MBR is located.
MBR size
Max. 2 TB per partition. limited to 4 partitions. and a boot loader
Primary Partitions
the 4 main partitions of MBR partition.
Extended Partitions
Dividing a primary partition in multiple partitions and add logical drives to those partitions.
GPT partitioning stands for what?
GUID Partition Table(GPT). Works with UEFIBOSIS to give you extra features.
GUID stands for what?
Globally Unique Identifier. 128 -bit unique value.
GPT size
128 partitions per/drive, 18.8m terabytes / partitions
LBA 1
Contains the Primary GPT HEADR
File allocation table
A data structure that keeps track of the location of files and folders.
Fat16
a type of file allocation table. Called fat because it looks like a two column spreadsheet
FAT32
has 8 hexadecimal character instead of 4 like 16. Very old. Could support 8 TiB volumes.
Fragmentation
When a file is in two different spaces on the file allocation table.
NTFS stands for what?
New Technology File System(NTFS). Been around for a long time. dominant today. Supports up to 16 EiB volumes. Individual files can be up to 256 TiB. Primary for windows
MFT stands for what?
Master File Table, used with NTFS. Sits in the middle of your volumes.
ExFAT
The inbetween FAT32 and NTFS. Less overhead. Great for thumb drives.
CDFS stands for what?
Compact Disc File System. Standard for all optical media. And have files up to 4 GiB.
ext3 for Linux
Supports 32 TiB volumes, and files are up to 2 GiB. Are for Linux
ext4 for Linux
Supports up to 4 EiB volumes, and files up to 16 TiB. Are for Linux
HFS+ stands for what?
Hierarchical File System Plus for Mac OS. Dominant for Mac OS and supports 8 EiB volumes and files.
Disk Management
Windows uses disk management to partition and format disks.
Dynamic Disks
Unique to Windows. You can shrink and expand and span across multiple drives.
Spanned volume
you can take two disks to act like one. Not good to do.
GPT advice
- Keep boot drive basic (not dynamic). 2. Set boot drive to GPT. 3. Easy to create dynamic disks.
Software RAID
Uses the operating system to configure the RAID array.
Storage Spaces
A powerful tool to configure advanced software RAID arrays. And also provides great flexibility.
Types of encryption
File based encryption and disk-based encryption.
File-based encryption
encrypting files and folders
Disk-based encryption
encrypting an entire drive.
EFS stands for what?
Encrypting File System(EFS). Used in windows and built into NTFS. Allows you to encrypt files and folders
TPM stands for what?
Trusted Platform Module. A chip built into the motherboard with a encrypted key.
Bit Locker
a disk-based encryption used on windows. Requires TPM.
Storage Spaces
software RAID tool built into windows OS.
