Pre Test Block 2 Flashcards
study (100 cards)
Software that runs virtual machine and can install or run multiple VMs
Hypervisor
Hard drive interface providing faster transfer times, thinner more flexible cabling, and easier plug-an-play connections
SATA
Specialized storage device or group of storage devices providing centralized fault-tolerant data storage for a network.
NAS
Device that resides on the LAN as an independent network node and has its own IP address.
NAS
Import benefit is its ability to provide multiple clients on the network with access to the same file
NAS
_____ is appropriate for organizations requiring fault-tolerance and fast data access
NAS
Specialized high-speed network of storage devices and switches connected to servers or computer systems.
SAN
Not only are _____ extremely fault-tolerant but they are also extremely fast
SANs
Fibre channel connects devices within the _____
SAN
This storage type uses a faster more efficient method of writing data. Best suited to environments with huge quantities of data that must always be quickly available
SAN
What are the two types of RAID
Hardware and Software
How many levels does RAID have
5 (0,1,5,6,10)
Which RAID level has no fault-tolerance
RAID 0
What RAID level carries out mirroring or duplexing where the data on a disk is copied onto one disk or a pair of disks
RAID 1
Which RAID is the most common/popular
RAID 5
Both data and parity information are striped across 3 or more drives. Is what level of RAID
RAID 5
Has high read/write speed.
Good capacity and cost effective.
It’s not very efficient with large data transfers
RAID 5
Two parity block are written in this level to help in the data recovery process. Disadvantage the performance is not very good for small data transfers. Extension of RAID 5
RAID 6
What is the first event in the information processing cycle
Inputting data (IPOS)
Acquisition, Data Entry, Validation are sub-stages of ______
Input
Any peripheral device helping feed data and control signals to a computer system
Input Devices
What are the two types of Input Devices
Direct input devices (Touchscreen), Indirect pointers (Mouse)
Types of peripheral hardware connected to the computer either using cables or over a wireless network
Output Devices
Create a hard copy rendition of a digitally rendered design
Plotters
