A network router allows you to:

1. Connect Multiple Devices: It enables multiple devices, such as computers, smartphones, and printers, to connect to the internet through a single broadband connection.
2. Direct Network Traffic: Routers manage and direct data traffic within the network, ensuring that data packets reach their intended destinations efficiently.
3. Provide Network Security: Many routers include built-in firewalls to protect the network from unauthorized access and cyber threats.
4. Assign IP Addresses: Routers assign local IP addresses to devices on the network using DHCP (Dynamic Host Configuration Protocol), facilitating communication among devices.
5. Facilitate Wireless Connections: Wireless routers allow devices to connect to the network without physical cables, providing flexibility and mobility within the coverage area.
6. Enable Advanced Features: Some routers offer features such as Quality of Service (QoS), which prioritizes bandwidth for specific applications, and guest networks for secure access for visitors.
7. Manage Network Traffic: Routers can analyze and manage the traffic on your network, helping to optimize performance and reduce congestion.
8. Connect to Other Networks: Routers can connect your local network to other networks, including other local networks or the wider internet, functioning as a gateway.
