About Business

A Port Checker Tool is an online or offline tool that checks the status of a network port. A port is like a door in your computer or server. Data enters and leaves through these doors. Each service uses a specific port number, such as port 80 for websites or port 443 for secure websites. The main job of a port checker tool is to tell you whether a port is open, closed, or blocked. When a port is open, it means the service connected to that port is working and accessible. If the port is closed, the service may be down or blocked by a firewall.
