A bug, in the context of computing, is a term used to describe a flaw or mistake in a software program’s code that produces a wrong or unexpected result, or behaves in unintended ways. Bugs can cause a program to crash or freeze, produce incorrect data, or act erratically. They can also be security vulnerabilities, which are mistakes that allow an attacker to compromise a system’s security.
1. What causes bugs in software?
Bugs in software are typically caused by human errors in the program’s source code or its design. This can include incorrect assumptions made by programmers, typographical mistakes, or misunderstanding the software’s specification.
2. How are bugs detected and fixed?
Bugs are detected through various ways such as software testing, code reviews, and user feedback. Upon detecting a bug, developers debug the program which involves identifying and removing the piece of code causing the problem, then testing the program to ensure the bug has been correctly fixed.
3. What is a ‘bug report’?
A bug report is a documenting process where the identification, description, and status of a bug is recorded. It’s used to notify programmers about a flaw in their program so they can fix it. A powerful tool for communication between developers and users, feedback, or testing departments.
4. What is ‘debugging’?
Debugging is the process of finding and resolving bugs or defects within a computer program that prevent correct operation of computer software or a system. This includes stepping through the program, stopping or pausing it to check its state, and tracking the values of variables.
5. What is a software ‘bug tracker’?
A bug tracker, also known as issue tracker, is a software application that is used to keep track of reported software bugs in software development projects. It may also be used to organize and prioritize the list of bugs, keep track of work completed, and provide reports on the bug trends.
