In today’s digital world, routers play a crucial role in connecting us to the internet. Whether you're streaming videos, playing online games, or working remotely, your router determines your connection speed, stability, and security. But how do routers work, and what should you consider when choosing one? This guide will cover everything you need to know about routers.

1. What is a Router?

A router is a networking device that connects multiple devices to the internet and directs data between them. It acts as a traffic manager, ensuring that the right data reaches the right device efficiently.

Routers can be wired or wireless (Wi-Fi routers), depending on how they transmit data.

✅ Wired routers use Ethernet cables for direct connections, offering faster and more stable speeds.
✅ Wireless routers (Wi-Fi routers) allow devices to connect without cables, providing mobility and convenience.

2. How Does a Router Work?

Routers work by:

1️⃣ Receiving data from your internet service provider (ISP) via a modem.
2️⃣ Assigning unique IP addresses to connected devices.
3️⃣ Directing traffic to the correct device using packet switching.
4️⃣ Managing multiple connections to ensure smooth data flow.

In short, routers translate and distribute internet data between your devices, preventing congestion and improving efficiency.
