What are bugs? Explain the variables to a bug. - Repeatability, Visibility and Severity

Programming errors are termed as bugs.

Repeatability: If a bug has been found, one should quit the application and try to find the same bug again with minimum set of steps needed for the bug to occur. If one can repeat the bug again and again, that’s what determines repeatability.

Visibility: Visibility refers to whether the bug is visible to the end user or not.

Severity: Severity determines the magnitude of implications of the occurrence of the bug. I.e. how much impact the bug has and at how many places.
