3. What is subnet Mask ?

       A subnet (short for "subnetwork") is an identifiably separate part of an organization's

network. Typically, a subnet may represent all the machines at one geographic location, in

one building, or on the same local area network (LAN). Having an organization's network

divided into subnets allows it to be connected to the Internet with a single shared network

address. Without subnets, an organization could get multiple connections to the Internet, one

for each of its physically separate subnetworks, but this would require an unnecessary use of

the limited number of network numbers the Internet has to assign. It would also require that

Internet routing tables on gateways outside the organization would need to know about and

have to manage routing that could and should be handled within an organization.

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

          A gateway is a routing device that knows how to pass traffic between different subnets and

networks. A computer will know some routes (a route is the address of each node a packet

must go through on the Internet to reach a specific destination), but not the routes to every

address on the Internet. It won't even know all the routes on the nearest subnets. A gateway

will not have this information either, but will at least know the addresses of other gateways it

can hand the traffic off to. Your default gateway is on the same subnet as your computer, and

is the gateway your computer relies on when it doesn't know how to route traffic.

The default gateway is typically very similar to your IP address, in that many of the numbers

may be the same. However, the default gateway is not your IP address. To see what default

gateway you are using, follow the steps below for your operating system.
