Software issues are problems that can arise with software, such as BUGS, glitches, or other malfunctions. BUGS are the most common type of software issue and are caused by errors in the code. These errors can cause the software to behave unexpectedly or crash altogether. Glitches are less severe than BUGS, but can still cause unexpected behavior. Other software issues can include compatibility issues, security vulnerabilities, and performance issues. All of these issues can be addressed through proper testing and maintenance.
