Desktop Engineer Interview Question:

What is a default gateway? What happens if I don't have one?

Submitted by: Muhammad

A default gateway is a routing device used to forward all traffic that is not addressed to a destination within the local network or local sub-net. If you don't have a default gateway, it is not possible to communicate with the network device/host of different networks. Dial-up internet connections do not require a default gateway though because it is present in the ISP itself.
