What Is Network Testing?
Network testing refers to the process of assessing and validating the performance, reliability, and security of a network. It helps identify issues such as latency, packet loss, and bandwidth bottlenecks, ensuring that the network performs optimally under varying conditions.
Why Is Network Testing Important?
- Enhances User Experience: Ensures applications run smoothly without interruptions.
- Improves Security: Detects vulnerabilities that could compromise sensitive data.
- Optimizes Performance: Identifies and resolves network bottlenecks.
- Supports Compliance: Ensures the network meets industry standards and regulations.
For professionals taking QA tester training, network testing knowledge equips them to troubleshoot real-world issues effectively, making them valuable assets to their teams.
