47.Explain submit mask and subnetting and advantages.
Ans.
1. The network mask is also called the subnet mask. All network nits were set to one and the host bits were to zero. This is the standard format for all the network masks.
E.g.
Class C 11111111 11111111 11111111 00000000
Class B 11111111 11111111 00000000 00000000
Class A 11111111 00000000 00000000 00000000
2. A subnet enable us to use one IP address and split it up so that it can be used on a several physically connected local network, it’s a big advantage, as the number of IP numbers available is rapidly diminishing.
3. We can have the multiple subnetted networks connected to the outside world with just one IP address.
4. By splitting the IP address, it can be used on sites that need multiple connections; splitting the address eliminates the problems of high traffic and difficult manageability.
5. Subnetting also increases security by separating into local networks.
