Some Vocabulary Flashcards
External Serial Advanced Technology Attachment (eSATA)
An extension to the SATA standard that enables SATA drives to attach externally.
Flash Memory
Electronic non- volatile memory that is easy to erase and reprogram.
Hard Disk
A long term storage device, a thick magnetic disk made of several aluminum platters in a protective shell.
Integrated Drive Electronics (IDE)
An electronic interface that allows communication between a motherboard’s data pathos or bus and a computer’s hard disks.
Just a Bunch of Disks (JBOD)
A configuration that places multiple disks in a single logical storage unit.
Non-Volatile Memory Express (NVMe)
A memory storage device designed to allow access to non-volatile storage media through a PCI express (PCIe) bus.
Optical Disc
A storage device that records binary information through pits in a reflectively coated disc.
Optical discs use lasers for reading and writing information.
Optical drive
The disc drive that reads and writes data from optical media
Optical media
Discs that are easily portable and can store large amounts of data.
M.2
A popular solid state drive often used in portable electronics.
Redundant Array of Independent Disks (RAID)
A disk sub-system that combines multiple physical disks into a single logical storage unit.
Serial ATA (SATA)
The latest generation of standards for hard disk and other storage devices.
SD card
A flash memory device is often used in digital cameras.
Solid state drive
A flash device with a large storage capacity comparable to a hard disk drive’s.
Directory
A container in a volume that holds files or other directories.
Extended File Allocation Table (ExFAT or FAT32)
A special file system designed to support large flash drives.
File
A file is a one-dimensional stream of bits treated as a logical unit.
File system
A means for organizing, storing data and information on a storage device.
Formatting
The process of preparing a partition to use a specific file system.
New Technology File System (NTFS)
Microsoft’s default file system
Volume
A single accessible storage area within a file system.
Initialize
Prepare a new disk for use.
Partition
A section of a hard disk separate from the rest. Partitions allow the OS to manage the information in each section separately.
Storage Spaces
helps protect your data from drive failures and extend storage over time as you add drives
by allowing you to group drives into a storage pool and make data backups.
Extended Volume
An extended volume has unallocated disk space on the same disk.
Mount point
A mount point is an empty folder on an existing volume that points to another partition. Data saved to the folder is physically saved on the referenced partition.
Spanned volume
A spanned volume has unallocated disk space on a different disk.
Storage Space
A Windows function that allows you to group physical disks into storage pools and create virtual disks from the available capacity.
Parity
It uses parity information to reconstruct data if one of the storage devices fails.
Usually requires at least three disks.
Simple data Provisioning
This option simply adds space from the storage pool to the storage space.
When you select the Simple option, all of the data in the storage space is lost if one of the drives fails.
Thin provisioning
An option that allows you to allocate larger storage spaces than the disk space available in the pool.
Three-way mirror
Requires at least five storage devices. The data is written to three storage devices. This option provides redundancy for the data if two storage devices fail at one time.
Two-way mirror
Requires at least two storage devices. The data is written to two devices. Two-way mirror requires twice as much device space as the amount of storage allocated to the storage space. This option protects you from a single storage device failure.
Disk Defragmenter
A program that optimizes the performance of your hard drive by joining fragments of files that are in different locations on your hard drive into a single location.
System Restore
A Microsoft feature that lets you revert a computer’s state to an earlier period in time.
Windows Update
