- Functional Bugs: These bugs affect the core functionality of the software. They can prevent the software from performing its intended tasks. For example, a functional bug in a word processing application might cause it to crash when attempting to save a document.
- Performance Bugs: Performance bugs impact the speed and efficiency of the software. This can include slow loading times, unresponsive user interfaces, or inefficient use of system resources.
- Compatibility Bugs: Compatibility bugs occur when software doesn't work as expected on certain hardware or software configurations. For example, a website may not display correctly on a particular web browser.
- Security Vulnerabilities: Security bugs are among the most serious. They can create vulnerabilities that hackers or malicious actors can exploit to gain unauthorized access, steal data, or cause other security breaches.
- Usability Issues: Usability bugs relate to the user experience and interface design. These bugs can make software confusing, difficult to use, or counterintuitive, leading to user frustration.
- Memory Leaks: Memory leaks occur when a program fails to release memory it has allocated, leading to a gradual increase in memory usage. Over time, this can cause the software to become sluggish or eventually crash.
- Logic Errors: Logic errors are bugs in the program's underlying code that cause it to produce incorrect results or behave unexpectedly. These errors can be challenging to detect because the program may still run without crashing.
