What is Network Congestion? What can cause it?

Network congestion occurs when there is too much data to transmit on a network and it doesn't have enough capacity to handle the demand. This can lead to increased latency and packet loss. The causes can be multiple, such as high network usage, large file transfers, malware, hardware issues, or network design problems. To prevent network congestion, it's important to monitor your network usage and implement strategies to limit or manage the demand.
