Redundant Array of Independent disks What is a RAID?
RAID 0 Known as disk striping
Useful when you need to speed up disk access, but is not fault tolerant. Disk striping
RAID 1 Referred to as disk mirroring
RAID 5 is the most common RAID configuration
It requires a minimum of three hard disk drives for implementation. RAID 5
RAID 3 uses disk striping with a parity bit and requires a minimum of three hard disk drives to function
RAID 4 This level offers greater access speed than RAID # because it can store data in blocks and, thus, does not need to access all disks in the array at once to read data
RAID 6 Adds a second set of parity bits for added fault tolerance and allows up to two simultaneous hard disk drive failures while remaining fault tolerant
RAID 0 & 1 Are handled by software running on an operating system
dd command writes the ISO image to your USB flash memory drive.
a script that automates the installation of Linux kickstart file
A distributed filesystem developed by Sun Microsystems that allows computers of differing types to access files shared on the network. NFS Network File System

RAID configurations can be handled by _______ running on an operating system called _______ RAID. software, software
What is more a more common way RAID is handled within a SCSI or SATA hard disk controller. hardware
RAID configurations can also be handled by the system _______ and are called _______ RAID. BIOS, Firmware
What is the most common installation method for Linux computers? DVD-based installation
Linux installation methods CD, USB flash drive, hard disk, DVD, and Network-based

An _________ CPU is a CPU that is faster than the speed for which the processor was designed. overclocked
What are the two installation log files created by the Fedora installation program? /root/install.log and /root/install.log.sys
After installation, you can ensure that Linux has detected the correct amount of RAM by viewing the contents of the ________ file. /proc/meminfo
What command can you use after system startup to view the hardware detected during boot time? dmesg | tail
Most Linux distributions contain a small bootable Linux kernel and virtual filesystem that can be loaded into RAM and used to fix problems that prevent Linux from functioning properly or loading at system startup. System Rescue

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
