A router is a device that connects multiple devices to the internet and helps them communicate with each other. It acts as a traffic director for your home or office network, ensuring data goes where it needs to.
How Does a Router Work?
When you connect a device like a laptop or smartphone to a router, the router assigns it an address on the network. This address helps it identify which device is sending or receiving data.
For example:
a. You open a website on your phone.
b. The request goes to the router, which sends it to the internet through your modem.
c. The website’s data returns to the router, which delivers it to your phone.
A router also uses firewalls and settings to block unauthorised access, keeping your network safe.
Why Do We Use a Router?
– Share Internet: A router lets multiple devices, like laptops and smart TVs, use the same internet connection.
– Wireless Connectivity: Routers with Wi-Fi enable cable-free internet access.
– Network Security: They prevent hackers from directly accessing your devices.
Think of a router as the middleman, managing your internet and ensuring smooth communication between your devices!
