What is the Stub file?
Stub is a computer file that seems to be on the end user's hard disk, but in fact it is partly hosted at another place of the storage. The most common secondary placement for the Stub file is a network storage in which the information is hosted online or on a network server physically connected to the system network. The main advantage of using Stub files is that they make additional space available on the end user's hard drive, allowing you to save multiple files and programs in the system. One of the primary disadvantages is that access to the Stub file requires continuous and continuous access to a network computer containing a file. The Stub file acts as a type of surrogate symbol and reminds of computer - and computer users - that the file is available for access. Once the end user approaches the Stub file, the computer takes the information about the location of the inside and points to the network device driver. The network card on the computer approaches the location of the network storage where the UP is storedFull content of the Stub file, returns the information to the end user's computer and displays it on the screen like any other active file. From now on, the end user can see and edit the file as if it were in fact and fully contained on the hard disk of the physical computer.
Stub files are generally used as a cost savings device. They allow organizations with a significant amount of data to move the mass part of their data to a cheaper storage solution, such as storage of magnetic tapes or hard drives with lower speed. This allows organizations to store their more expensive and faster hard drives for vital files and programs, with their archive or recording files moving to cheaper storage medium.
Access to Stub files is generated by slower than access to files because computers must use network resources to use them, on RODue to collecting data directly from the hard drives of host computers. In addition, the ability to access the stub files depends on the constant network operation and storage medium host of the full content of the file; If it either drops, all stub files become inaccessible until the problem is resolved.
