A computer error that suddenly pops up while you are working in your computer can really ruin your day. Here, you will be provided with information to help you understand the various problems you encounter in your computer.

CRC Errors

These errors happen during the transmission of data. To prevent these errors, CRC or Cyclic Redundancy Check is used. This technique detects automatically as you attempt to open the data received in your programs such as the Internet or various media transmission such as CD-ROMS, floppy disks and etc.
The caused of these errors are generally because of lost data while on the process of transmission, connection errors in transmission, or transmitting damaged media files.

In repairing these CRC errors you have to ensure the stability of your connection while transmitting such as the Internet connection, cable connectors and the service provider’s end. If transmitting media files, make sure that the used media is not defective. And if in case that the problem is none of the said manner, then damaged transmitted data might be the problem.
