What is the scratch?
Scratch Space is usually a hard disk storage that is used for temporary memory, especially when working in a program that may require a large amount of backup space. This disk area may then allow you to store temporary files from the Internet or from the program used. Although it does not work exactly as a memory with random access (RAM), Scratch Space can often provide similar benefits for computer users. Usually it is best if it is placed on a different unity than the main unit of the computer to ensure that the appropriate storage is available, even if new programs and files are added.
The purpose of scratching on a hard disk is to provide a system user with additional memory when you start applications. This is usually a temporary repository, similar to a piece of scratching paper is used for temporary work in the real world. For example, photographing photos on a computer may have them on a scratch on the computer. Once the images are stored,They are then permanently stored on the hard disk of the computer, although they can still remain in a temporary storage.
In some respects Scratch Space works similar to RAM on a computer. RAM is a memory used by programs and applications, which is not permanent and is erased every time the power is turned off to the computer. Scratch Space in the system is similarly temporary, even if it is on the hard disk, and therefore does not rely on the strength to maintain the data about it. By using this type of repository, RAM can be liberated on a system that focuses primarily on other tasks, while the data is backed up on scratches.
On many systems, scratches can be set by default on the same hard drive as the operating system (OS) and other programs. However, this can cause problems because other files and software are mined for OS. The hard disk begins to fill in from these types of programs that leave on the diskless space for scratches. Problems may arise because the computer is no longer able to use the scratch area, because there are other stored data. Often it is best for the data to be scratched on the second unit or in the area divided into a disk, specifically for this purpose.
