Image of router with corresponding parts and its function

Here are the common parts of a typical router and their functions:

1. Power Port/Jack: This is where the power adapter connects to supply electricity to the router.
2. Power Button: Used to turn the router on or off.
3. WAN/Internet Port: This port (often labeled "Internet" or "WAN" and sometimes a different color like blue or yellow) connects the router to your modem, which provides the internet connection from your Internet Service Provider (ISP).
4. LAN/Ethernet Ports: These ports (typically 4, often labeled 1-4) are used to connect wired devices (like computers, gaming consoles, smart TVs, or network printers) to the router using Ethernet cables, providing them with network and internet access.
5. Antennas: These are responsible for transmitting and receiving wireless (Wi-Fi) signals, allowing devices to connect to the network wirelessly. Some routers have internal antennas.
6. Reset Button: A small, often recessed button (requiring a paperclip or pin to press) that, when held down for a few seconds, restores the router to its factory default settings.
7. USB Port(s): Found on some routers, these ports can be used to connect external storage devices (like USB hard drives for network sharing), printers (to make them network printers), or 3G/4G dongles for backup internet.
8. LED Indicators: Small lights on the front or top of the router that show the status of various functions, such as:
   • Power: Router is on.
   • Internet/WAN: Indicates an active internet connection.
   • Wi-Fi: Indicates the wireless network is active.
   • LAN: Shows activity on the wired LAN ports.
9. WPS (Wi-Fi Protected Setup) Button: Allows for easy and secure connection of Wi-Fi devices to the network without manually entering the password.
