19 Subnet Mask This option is used to enter the subnet mask. A
subnet mask is used to reduce the traffic on each
subnetwork by confining traffic to only the subnet-
work for which it was intended. A subnet mask
makes the entire network more manageable. In
effect, each subnet functions as though it were an
independent network, keeping local traffic local and
forwarding traffic to another subnet only if the
address of the data is external to the subnet. The
Subnet Mask is written in the format
XXX.XXX.XXX.XXX, where each 3-digit field has a
value between 000 and 255.
20 Gateway This option is used to enter the default gateway/
router between the internal network and the exter-
nal network. The Gateway address is written in the
format XXX.XXX.XXX.XXX, where each 3-digit field
has a value between 000 and 255.
21 Date This option is used to enter the date (MM/DD/
YYYY).
22 Time This option is used to enter the time (HH:MM:SS).
