Troubleshooting is the process of identifying, analyzing, and resolving problems or issues that occur with a computer system, software application, or hardware device. Troubleshooting involves using various techniques and tools to diagnose the cause of the problem, such as running diagnostic tests, checking system logs, and using specialized software. Once the problem has been identified, troubleshooting typically involves implementing a solution or workaround, such as reinstalling software, updating drivers, or replacing hardware components. Troubleshooting is an important skill for IT professionals, system administrators, and advanced users, as it allows them to maintain the performance and reliability of their computer systems. Troubleshooting can also be performed by end-users to resolve common issues, such as connectivity problems, software errors, and system crashes.
