CRC

Přípona souboru crc se používá pro soubory kontrolních součtů.

CRC je technika pro zajištění spolehlivosti dat. CRC se používá k ochraně bloků dat nazývaných Frames.

CRC je jednou z nejpoužívanějších technik pro detekci chyb v datové komunikaci.

The crc file extension is also used for one for one of the temporary files in old Pro/ENGINEER software.

Temporary files may be created by computer programs for a variety of purposes; principally when a program cannot allocate enough memory for its tasks, when the program is working on data bigger than architecture's address space, or as a primitive form of inter-process communication.

The crc file extension is also used by Total Commander for its cyclic redundancy check files.

The CRC is a very powerful but easily implemented technique to obtain data reliability.

The CRC technique is used to protect blocks of data called Frames. Using this technique, the transmitter appends an extra n- bit sequence to every frame called Frame Check Sequence (FCS).

The FCS holds redundant information about the frame that helps the transmitter detect errors in the frame. The CRC is one of the most used techniques for error detection in data communications. The technique gained its popularity because it combines three advantages:

• Extreme error detection capabilities.
• Little overhead.
• Ease of implementation.
