Computer technology is carefully the most beneficial thing to ever happen to the world presently. all has been made easy because of this technology. The world has become faster and more sufficient because of computers. Along with many advantages come disadvantages as well. One of these disadvantages is protection breach of information. It has become relatively easy for possible thieves to steal information from your computer, most especially when you are linked to the Internet. Many citizen have solved this problem by deleting files. Unfortunately, this is not enough. Hackers can still get the said information from your hard disk even though you have already deleted them. Experts suggest the need to overwrite free disk space. Why is that?
Most citizen think that deleting files is the end of it all. Unfortunately this is where many citizen are mistaken. Even though you have already deleted the files and emptied your recycle bin, the files are still in your hard drive physically. When you are deleting files, what happens within the operating law is that it does not nothing else but erase the file completely. It just reMoves its reference from the File funds Table. This reference pertains to the exact space where that files were stored. When the operating does not see this reference, what it does is that it marks the said file as free space when, in fact, the file concerned is still physically inside your hard disk. It can only be deleted when someone else file takes over its allocated space.

Knowing this fact about how computers work, hackers know how they can retrieve these files. This is a possible threat to Internet users, especially the ones working for huge companies. Fellowships nearby the world lose millions of dollars to hackers because of this vulnerability. A solution to this dilemma is wiping free disk space.
The whole process of completely erasing those files from the hard drive is very tedious and hard. Some citizen believe that one overwrite will not do. They say that it will take more, possibly even more than twenty overwrites. Some even believe that the most carefully and talented hackers can still recover the file, even though it has gone to more than 20 rewrites. To be nothing else but sure that the files are no longer recoverable, many citizen create software that intentionally write blank characters over them. These applications do the overwrite several times in a few seconds. By doing so, these programs have ensured that the files are completely erased physically from the hard drive. Even if the hackers can still retrieve some bits of information, it is no longer that comprehensible to be reconstructed.
The world of computers and information technology has brought to us both advantages and disadvantages. When we connect to the information superhighway, we expose ourselves to the danger of protection breach. information may be accessed by hackers and used for their own advantage. Come to think of it, practically whatever is possible in the virtual world. This easy fact is good enough presume to overwrite free disk space. Not only will you be protecting yourself, you will also be protecting your company.
