As a result of this, we can see that there are different types of error which includes:
- <u>Gross errors</u>
- <u>Random errors</u>
- <u>Computer errors</u>
- <u>Systematic errors</u>, etc
With this in mind, it is worth noting that when an error is made, they can be rectified so that the original process can continue without further problems.
For example, in the case of a computer error which is commonly called a bug, then <em>the program cannot run,</em> until such error is removed, then the program can execute successfully.
