How does a computer error occurs.
There are several ways that computer errors occur. The most common is actually user error. The user of the program does something that the program is not designed to do, or expects the program to work in a way other than it does.
Another common cause of computer errors is bugs. Bugs are errors in the way the program is written or works. The errors caused by bugs range from incorrect calculations or responses to program crashes to full computer crashes.
A less common cause of computer errors are interactions between programs. Occasionally a program may do things that cause another program to have an error. This can include alter or deleting files that the other program needs, changing memory that the other program is using or sending bad or faulty commands to the other program.
