What is the purpose of a Hot Spare in a RAID array?
Used to replace a failed drive in a redundant array.
Difference between Internal hashing n external hashing?
Internal hashing mainly used for internal file, it is particularly an array of records. External hashing used for file disk
Difference between array processor and multiprocessor?
an array processor can handle multiple data elements simultaneously,in a parallel fashion, but a multiprocessor handle multiple processes simultaneously which may include more than one data element in each process... An array procesor is optimized for array operations, has its own set of instructions, large memory block moves, logical operations on many array elements, etc and may itself be multi-processor or massively parallel. It has an interface where a host loads memory locations with the array to be processed (or perhaps a data file), then the array processor uses its specialized structure to do what was asked of it on the array, then tell the host is done and the result may be found in memory locations or perhaps a data file. Many of the jobs supercomputers do are array operations, the specialized capabilities can cost thousands of dollar per CPU second but they can do array operations that might take years for slower general purpose computers. An array procesor can also be smaller, a graphics processor handling the video display is an array processor. A typical operation is move the image to the right, move all the pixels to the right.. A general purpose computer may be multi-processor (Intel's multi-core).
Differentiate single dimensional array to double dimensional array?
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
What is meant by irregular dimensional array?
An irregular dimensional array is a special type of multi-dimensional array.First we must understand that a multi-dimensional array is just an array of arrays. Each element in the array is, itself, an array of elements.A regular multi-dimensional array will be an array of size n, with each element containing a separate array of size m. That is, each sub-array has the same size.An irregular multi-dimensional array will be a multi-dimensional array in which each sub-array does not contain the same number of elements.Regular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4, 5}array[2] = new array{6, 7, 8}array[3] = new array{9, 10, 11}This regular array is an array of size 4 in which each sub-array is of size 3.Irregular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4}array[2] = new array{5, 6, 7}array[3] = new array{8, 9, 10, 11}This irregular array is an array of size 4 in which the size of each sub-array is not the same.
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
What is the purpose of a Hot Spare in a RAID array?
Used to replace a failed drive in a redundant array.
What is the purpose of a disk warrior?
There are many purposes of a disk warrior. The main purpose of a disk warrior is to recover one's files on their computer including their music, photos, and documents.
Which array disk tasks are recommended when replacing a hard drive?
Offline and then Prepare to remove
What is a disk array?
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.
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 is the purpose of AND array?
AND array is used for developing digital circuit it is used in PLA programmable logic array and PAL programmable array of logic to implement the function. the number of and array will depend on how long you has function to be implemented.These are Digital circuits.
