IT Vocab PC9 Flashcards
To run a CPU or video processor faster than its rated speed
overclocking
Method of error detection where a small group of bits being transferred is compared to a single bit set to make the total bits odd or even
parity
Two or more drives in a group that are used for a striped volume
stripe set
Process by which data is written simultaneously to two or more disk drives. Read and write speed is decreased but redundancy in case of catastrophe is increased
disk mirroring
Replacing a bad drive in a RAID array without needing to reboot or power down
Hot-swapping
Disk optimization feature for SATA drives enabling faster read and write speeds
Native Command queuing (NCQ)
RAID 0 volumes or data is spread across two drives for increased speed
striped volumes
Data storage device that uses flash memory to store data
solid-state
Hardware connection with some sort of projection that connects to a port
plug
hidden table that records how files on a hard disk are stored in distinct clusters; the only way DOS knows where to access files
File allocation table
SSD technology that supports a communication connection between the operating system and the SSD directly through a PCIe bus lane, reducing latency and taking full advantage of the speeds of high-end SSDs
Non-Volatile Memory Express (NVMe)
Designator used to ensure proper alignment of floppy drive and hard drive connectors
pin 1
casing that encloses an external hard drive
external enclosure
if the controllers are enabled and the drive is properly connected, the drive should appear in CMOS through a process called _________.
autodetection
Storage devices that read and write data encoded magnetically onto spinning aluminum platters
magnetic hard drives
Connects SATA devices to the expansion bus
host bust adapter (HBA)
uses block level and parity data striping which requires three or more drives
RAID 5
the opposite of RAID 0+1 with two mirrored RAID 0 configurations and provides both speed and redundancy requiring 4 disks
RAID 10
The Linux equivalent of the Blue Screen of Death or error for which the OS can’t recover without a reboot
Kernel panic
PC specification for small to medium sized hard drives in which the controlling electronics for the drive are part of the drive itself, speeding up transfer rates and leaving only a simple adapter
integrated drive electronics (IDE)
Serialized successor to PCI and AGP that uses the concept of individual data paths called lanes
PCI express
uses byte level striping and provides no fault tolerance
RAID 0
the newest version of SATA that ties capable drives directly into the PCI express bus on motherboards
SATAe
Serialized version of the ATA standard that offers many advantages over PATA technology, including thinner cabling, keyed connectors and lower power requirements
Serial ATA (SATA)
Storage devices that combine the flash memory used in solid-state drives with the spinning platters used in magnetic hard drives
hybrid hard drives (HHDs)
the type of nonvolatile RAM that held information about the most basic parts of your PC, such as hard drives, floppies, and DRAM
CMOS
