A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks. For example, some 16-bit CRC schemes swap the bytes of the check value. Omission of the high-order bit of the divisor polynomial: Since the.

Here is my assignment:CIS 215 C ProgrammingProgramming Assignment #2Due Date: 10/21/13The Cyclic Redundancy Check is an algorithm that is used to find errors in data that has been stored or transmitted. Since every file or message can be thought of as a single pattern of bits it can be treated as a single large binary number.
Table Of Contents.Welcome to our tutorial on how to fix the data error: cyclic redundancy check. In this tutorial article, you will find everything you will need to know about this data error.We will begin by telling you what this error is before moving on to the possible solutions, of which there are two. What Is A Cyclic Redundancy Check Error?So, the first thing that you need to know before attempting to fix this problem (or any other computer problems, for that matter) is to know what it is. Not only will this help you understand what causes the problem but it will also most probably help you fix it.This error affects computers trying to access disks. These disks could either be, CDs (what we normally refer to as optical disks); or your hard drive (what is normally known as a hard disk). The cyclic redundancy check error happens when there is a problem whereby your computer is not able to verify the data on your disks.The name of this error comes from the method computers use to verify the data on your those disks. This method is known as cyclic redundancy check, often referred to by the acronym CRC.
What Causes A Cyclic Redundancy Check Error?Now that you know what the error is, you are probably wondering what usually causes it.There is not just one cause for this; there are in fact many possibilities. One of them is that your hard disk has become cluttered but there are also other possibilities, which are listing here:. Registry corruption.
A program that was not been installed successfully. that are not configured correctly.In this case, knowing the specific reason causing the error is not all that important in fixing this serious error. We have listed the possible reasons here because they may help you prevent this error from happening in the future.If you are experiencing this error currently, you will need to work on fixing it as soon as possible. We cannot emphasize how important this is because you could lose a lot of data or your system may totally fail.But it is not all bad news. Fortunately, despite the fact that this error is extremely serious it is also very easily fixed.Read on for ways to fix the error.Fix Number OneThe first method for fixing the cyclic redundancy check error involves using the Check disk utility, also known as CHKDSK utility.You do not need to download or install anything because the check disk utility is included in computer.
This utility exists for scanning and repairing any errors affecting the drive. There is an alternative for Mac computers, known as the Disk utility but this error is a lot less common on, so we are just going to focus on Windows machines.If the problem is caused by an optical disk, such as a DVD or a CD, you should remove the disk and check it for scratches.
If the disk does not seem to be scratched, then it is probably dirty, in which case you will need to dust it off. If you have never done this, grab a soft cloth and clean the disk gently but thoroughly (make sure that the cloth is dry). This method is great for detecting and fixing small problems.
If the problem is more serious then the scan will not complete because at some point it will become stuck. If this happens to you, then you should move on to the next fix.Fix Number TwoIf the check disk utility does not work then you should try a third party free disk utility.The best way to go about this would be to search the for a free disk utility and download it. There are a couple of popular ones but it is really up to you which one you decide to download and install.
Just make sure that you choose one that would work for your operating system, taking into account that there are different ones for Mac or for PCs.“To err is human, but to really foul things up you need a computer.” – Paul R. EhrlichOnce you have downloaded and installed the disk utility, open it and run the scan. We cannot offer you specific instructions on how to do this because different free disk utilities work slightly differently.
It should all be fairly straightforward and intuitive. Just follow the on-screen instructions.As with the inbuilt version, third party utilities can take up to several hours to complete so we recommend you leave this overnight (as you would normally for the advanced version we discussed earlier) or at least set out a few hours when you’re sure that you won’t need to use the computer.As a rule of thumb expect this scan to take anything between 2 and 4 hours. If it takes longer than that, this could mean that there is something seriously wrong with your hard drive.These are really the best two ways of fixing the data error: cyclic redundancy check.
