What is the storage near the line?
Storage Nextline, contraction of words "close" and "online" is a computer storage medium, which lies between online and offline storage, but is closer online. In this sense, online and offline do not refer to the use of the Internet, but how storage media is used. Online medium is on your computer; Offline requires human intervention and assembly, while storage near the line requires a certain human intervention, but is usually done by computer. Nearline is not as fast as online storage, but there is only a few seconds before the information available. Three main types of media near lines are magnetic tapes, magnetic discs and compact disks (CD).
The two main storage types are online and offline. Online refers to storage systems located on a computer such as a hard disk that does not require human intervention. Offline storage is a removable medium that must be connected and calibrated to the computer; It is very slow, but is able to hold a huge amount of memory of archiving.
The storage near the line lies between the two. It's like offline storage because the user must place storage media on your computer. In the online sense, the computer does most of the work because it knows how to find data and how to get it. Speed-wise, close line also lies between them. It is not as slow as offline storage, nor is it as fast as online, but it is only a short delay than the user can handle files in the media.
Businesses and large data centers are the main supporters of the nearby storage because it helps their database to optimize performance. When a close -line medium is used to use the data archive, it means that the database can stop using energy on this data and work on other features. At the same time, if the administrator uploads data from the near line back to the database, it will take much longer to cause harmful performance. Consumers also use a near line but usually nabThey are smaller storage media than busy businesses.
There are three different forms of a nearby line. The magnetic tape is like an archive tape, but is optimized for the use of a nearby line, so it does not require the same amount of preparation for use. A magnetic disk, such as a diskette, improves at speed and quantity of storage. The last of the Nearline media is the CD that is used to store data in many sectors.
