Storage Basics
This type of storage holds data permanently, even when the power is off.
What is secondary storage?
A hard disk drive stores data using this kind of technology.
What is magnetic storage?
This is what RAID stands for.
What is Redundant Array of Independent Disks?
This PSU component adjusts voltage levels before converting AC to DC.
What is a transformer?
This metal component with fins helps dissipate heat from the CPU.
What is a heat sink?
This type of memory is fast and temporary.
What is RAM (or primary storage).
This device uses a laser to read data from discs like CDs and DVDs.
What is an optical drive?
This RAID level offers striping with no redundancy.
What is RAID 0?
This PSU feature certifies energy efficiency under different levels of load.
What is 80 PLUS certification?
This paste improves heat transfer between the CPU and the heat sink.
What is thermal paste?
This type of memory stores data using electronic charges and has no moving parts. (Method, not the component)
What is flash memory?
A USB flash drive is an example of this kind of storage.
What is solid-state storage?
RAID 1 protects your data by doing this.
What is mirroring it on a second disk?
This type of PSU has all of its cables permanently attached.
What is non-modular?
This type of cooling uses a pump, radiator, and fluid to manage heat.
What is liquid cooling?
These two characteristics are typically improved when using an SSD over an HDD.
What are speed and durability?
This kind of drive spins at speeds like 5,400 or 7,200 RPM.
What is a hard disk drive (HDD)?
This RAID level combines mirroring and striping and requires at least four drives.
What is RAID 10?
This voltage rail is the most important for high-powered components like CPUs and GPUs.
What is the +12V rail?
This type of liquid cooling system is sealed and pre-filled by the manufacturer.
What is a closed-loop (AIO) system?
When a file is deleted, this is what actually happens to the data.
What is "it is marked as free space but not immediately erased?"
Name two disadvantages of optical storage.
What are slow speed and susceptibility to scratches?
This term refers to the error-checking data used in RAID 5 to rebuild lost information.
What is parity?
This happens when a PSU does not provide enough power for the system (2).
What are system instability and possible component damage?
This passive component helps reduce ripple in voltage but doesn't control the exact output voltage.
What is a capacitor?
