Managing Data Storage Flashcards
(22 cards)
BIOS Memory
Special memory that keeps track of its data even when the power is turned off, and is stored in EEPROMS.
Cache Memory
High-speed memory that the CPU can access directly.
Disk Duplexing
Disk mirroring in which the two drives in the mirror each have a dedicated disk controller.
Drive Rails
Metal strips that can be screwed onto an internal drive before installation.
Duplexing
The process that enables automatic printing on both sides of printing media, such as paper and envelopes.
ECC (Error Correction Code)
An error correction method that uses several bits for error-checking.
EEPROM (Electronically Erasable Programmable Read-Only Memory)
A ROM chip that can be reprogrammed by using software from the BIOS or chip manufacturer through the flashing process.
ESD (Electrostatic Discharge)
The phenomenon that occurs when electrons rush from one body with a static charge to another with an unequal charge, following the path of least resistance.
External Enclosure
A plastic barrier that protects the inner workings of a hard drive.
fdisk
A menu-driven utility program that is used for creating, modifying or deleting partitions on a disk drive.
File Recovery Software
Software that can recover deleted files from your computer system.
Flashing
Updating firmware electronically.
Memory Module
A system unit component that holds a group of memory chips that act as a single memory chip.
Mirroring
A disk fault-tolerance method in which data from an entire partition is copied onto a second drive.
Parity
An error correction method for electronic communications.
RAID (Redundant Array of Independent or Inexpensive Disks)
A set of vendor-independent specifications for fault-tolerant configurations on multiple-disk systems.
RAM (Random Access Memory)
A computer storage method that functions as a computer’s main memory.
RAM Module
A computer storage method that functions as a computer’s main memory.
SIMM (Single In-Line Memory Modules)
A RAM form factor with a 32-bit data path.
SMART (Self-Monitoring, Analysis and Reporting Technology)
A monitoring system that can help anticipate storage drive failures due to excess heat, excess noise, damaged sectors or read/write errors.
Storage Spaces
The Windows 8/8.1 implementation of RAID.
Striping
A disk performance-enhancement feature in which data is spread across multiple drives to improve read and write access speeds.
