What is the hash function?
and the hash features is a method of checking errors on your computer and data organization. A large amount of data is manipulated with mathematical algorithm until a small number is left. This number is used as part of the catalog that allows the computer to find this particular information later. A good hash function should provide a sufficiently small result, so it is easy to use, but provides a unique result for each data set. The hash also provides minimum error control because a damaged and good piece of data should bring different hash results.
In a computer database, it is usually easier to store locations rather than letters. The numbers have a much larger number of methods for organization and sorting than letters. As a result, the numbers are often assigned to places containing variable information in the computer database. These numbers can be any or representative for information.
lean numbers are simply assigned on the basis of a position in a computer tpama or the order in which the ULO data waswoman. Saving information in this way is common in smaller databases or in places where data does not change too often. When used in other areas, it will take more and more time indexing of the database until it is effective.
Representative information is where the hash function comes. Information, no matter what it contains, is translated into numbers. These numbers are fed to a mathematical construct that issues a small number, usually to an integer. If the hash function works correctly, each location in this part of the database will have its own unique result. If two or more places have the same result, programs could bring incorrect information based on duplicated hash.
It is possible to use the hash function for other things. A large number of highly recurring data can be a broke down to smaller values. This is especially nice in search of repeated sequences in VelData files. For example, deoxyribonucleic acid (DNA) consists of a very small number of different ingredients. When breaking these components using hash values, a place where two DNA chains are the same and different are very bright, simply comparing two small columns of numbers.
The last area in which the hash features are useful is error checking. If the information is initially hash, the value is recorded as part of the position index. If this information is needed later, the information is obtained with this value. If the program turns information again and the result is different, corruption occurred at a certain point. This corruption is usually with data because the corruption of hash would prevent data from loading the first place.
