In its simplest form an Array is a series of hard disks conected to one desktop computer.
More complex Arrays can be Redundant Array Inexpensive Disks or the Array could be Network Attached Storage depending on what the network requirements are.

What is the purpose of a disk array?
A disk array serves many purposes. It is a disk storage system that is capable of storing multiple disk drives. This product increases the availability and maintainability of stored information.
What is sda in computer?
Software Disk Array
Under what circumstances is a file more useful than an array?
For example: if you want to store data on a disk, it will be a file, not an array.
What are two possible remedies for a disk subsystem that is the bottleneck in a servers performance?
ANSWER Any two of the following: ■ Install faster hard disk drives. ■ Install additional hard disk drives and split your data among them, reducing the I/O burden on each drive. ■ Replace standalone drives with a RAID (redundant array of independent disks) array. ■ Add more disk drives to an existing RAID array.
If a raid 5 array is composed of 4 disk with 100 GB of storage each then what is the total capacity of the raid 5 array for data storage?
total disk space would be about 400 gb
Which array disk tasks are recommended when replacing a hard drive?
Offline and then Prepare to remove
Is a group of two or more integrated hard disk that acts like single hard disk?
It is called RAID (redundant array of inexpensive disks).
What is the application of phased array encoder?
Phased array sensors (PAS) for optical encoders are common in standard encoder in order to avoid reticles to match the code disk. Array of photodiodes are organised to recognize the disk ticks and make A and B channels. More information on Micropto web site. Typically phased array sensor (PAS) are monolithic silicon microchips with electronics to amplify the low signals from the photodiodes. Dimension of array on PAS is the limit of the resolution disk, each disk need a specific PAS pitch. Optical encoders adopt PAS or other sensors (phototransistors arrays, monolithics, ASIC, ...) to recognize the position and the speed of the motors in motion control.
What term is used to describe disk mirroring?
RAID 1. Redundant Array of Independent Disks.
What describes a group of two or more disk drives that appear to the system as a single drive?
Raid Array.
What does the acronym sda stand for in Linux os?
Scalable Disk Array =D Anthony Hopkins - not the actor
What level of raid does parity error checking occurs when data is written across the disk array?
RAID 3
