Network problems refer to issues that disrupt the normal functioning of a computer network. These can include slow internet speeds, connection drops, or complete outages. Common causes of network problems are hardware failures, software bugs, or configuration errors. Another aspect of network problems is security vulnerabilities, which can lead to unauthorized access or data breaches. Tools like firewalls and antivirus software are often used to protect networks from these threats. Regular maintenance and monitoring are essential to identify and resolve network problems before they escalate.
