Subnet Mask:
Subnet mask is a 32 bits value which
differentiate the host portion & network portion of an IP
address.
Where network portion is designate by the 1's & host portion
0's.
Wild card Mask:
Wild card mask defines which IP addresses are
allowed & which are blocked.
Where 0's defines the accurate match where non zero value
defines any value on the corresponding octete.

well shahin good to see you here again
subnet mask---subnet mask is the value which determine from
which class the ip address is realted.
wild mask-- Wild card mask defines which IP addresses are
allowed & which are blocked and used in extended access
list and ospf also.

Answer / sarbjeet sohi
Subnet-mask is used to match contigous bits, means in subnet mask there is no 1 after 0. Its always from high (1's) to low (0's).
EXAMPLE:- subnetmask-----255.255.0.0
BInary----- 11111111.11111111.00000000.00000000
In above example there is continous 1's and continous 0's
It cannot be like this :-
11111111.00000000.11111111.00000000 = 255.0.255.0
Because subnet mask is used only for the classful and when CIDR comes WILDCARD mask is launched. The above bit pattern in WCM tells to match 2nd and 4th octect.1st and 3rd can be ignored.

Answer / s.m.feroz ahmed
Hi,
Subnet mask is classified on class A,B,C,D,E at present we
are making use of class C ip addressing and the series of
class C starts from 191 to 227 so depending on class subnet
mask is defined for Class A subnet mask is 255.255.255.0
for Class B it is 255.255.0.0 and class C it is 255.0.0.0
and wildcard mask is just opposite to Subnet mask and it is
defined as 0.0.0.255 .

Answer / anshul johari
SUBNET- MASK IS A 32-BIT IP ADDRESS. AND IP ADDRESS TWO
DIVIDED NETWORK ID AND HOST ID. AND SUBNET MASK A SETTING IN
ALL BITS REPRESENTED "1" IS SIGNIFICANT AND "0" IS IN-
SIGNIFICANT.
WILDCARD MASK IS NOTHING BUT OPPOSITE TO SUBNET MASK SUBNET
MASK A SETTING IN ALL BITS REPRESENTED "0" IS SIGNIFICANT AND
"1" IS IN-SIGNIFICANT.

A server is running HTTP, SMTP and DHCP. Which of the following best explains how the server is able to handle all three services over the same connection? The server has separate buffer areas for each application and forwards all data to each service. If the data does not apply to that application, it is discarded. The server processes each packet one at a time and forwards the data to the application that indicates that it is waiting for a transmission to arrive. The data is discarded if it does not apply to that application. The server uses the destination port number in the TCP/UDP header to identify the service. The data is forwarded to the service identified by the port number. The server uses separate three-way handshake connections to control the flow of the data and relates the service to the proper connection. This relationship allows the server to pass the data to the proper service.
