What is the algorithm of the control sum?

Computer data is usually stored in binary files that are located in the computer file system. When data is stored on a computer, it is converted to a binary format. This converting process requires a file size to ensure that the entire file has been stored correctly. The control sum algorithm is a mathematical function that checks the files for corruption before storage.

Most business software applications allows users to create and save data files. This includes many Microsoft Office® products. When a Word® document is stored on the computer, the Word document is converted to a binary file. This conversion process requires an algorithm of the inspection sum to be verified correctly. If this feature detects and an error, the program will bring the user an error message.

Many users share data files between computers using E -mail. When the file is shared in e -mail, it is usually sent as an attachment. This connection process usesA to verify the algorithm of the control sums successful file transfer. The e -mail system will notify the user if the error is returned from the algorithm. This file transfer device ensures that the file is sent without errors. This is similar to the control sum algorithm. The primary purpose of the algorithm is to assign a numeric value. The value is based on the content size in the file. This value is used during the binary transfer process as an error control device.

Data entering is another area where the control sum algorithm can be used. This feature provides data verification on specific data. This process ensures that the correct format and types of data have been entered into specific input fields on the screen. As an example, the control sum algorithm can be used to verify the social security number.

Error of the Captispe of Jechyba that occurs when the control function failsthe sum. This usually occurs when a comparable file size is different, then expected. For the purposes of data verification, storage and transmission of files, a control sum is usually used.

When the computer is turned on, the control sum is performed. This function compares the values ​​of the input output system (BIOS) of an established computer to the previously stored values. If the numbers are different, the user is presented to the user's message identifying the configuration change. This is an example of a check all error.
