Router

The goal of this post is to reorganise what I have learned online over the past six months. I will deal with the in-depth content of each topic in a separate post if I have the chance later.

• WAN(wide Area Network) — A wide-area network called the Internet
• IP address ( internet protocol address) — Addresses for sending and receiving Internet communication between computers.
• LAN (Local Area Network) — Network that belongs to the same area.
• Router — A device that an intermediary in between WAN and LAN.

• When router and each device is connected to the router, it is automatically granted IP address.
• Gateway address or Router address — A special IP address to the router.
• Public IP address — IP address that allows you to access the router from within a WAN. Anyone in the world can access it.
• Private IP address — IP address that can only be used within a LAN.
