you successfully install Windows 2000 professional and you want to check your drives for errors. Name one way of checking for errors.
Error is a condition when the output information does not match with the input information. During transmission, digital signals suffer from noise that can introduce errors in the binary bits travelling from one system to other. That means a 0 bit may change to 1 or a 1 bit may change to 0.
Whenever a message is transmitted, it may get scrambled by noise or data may get corrupted. To avoid this, we use error-detecting codes which are additional data added to a given digital message to help us detect if an error occurred during transmission of the message. A simple example of error-detecting code is paritycheck.
Along with error-detecting code, we can also pass some data to figure out the original message from the corrupt message that we received. This type of code is called an error-correcting code. Error-correctingcodes also deploy the same strategy as error-detecting codes but additionally, such codes also detect the exact location of the corrupt bit.
How to Detect and Correct Errors?
To detect and correct the errors, additional bits are added to the data bits at the time of transmission.
The additional bits are called Parity bits. They allow detection or correction of the errors.
The data bits along with the Parity bits form a code word
