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.
47) What is DNS and why do we use it on workstations?
The Domain Name System (DNS) is used to resolve human-readable host names like www.globalguideline.com into machine-readable IP addresses like 184.108.40.206. The DNS address is configured on workstations. Windows redirects all domain names to resolve into IP addresses.
