Yes, a nic can have more then 1 IP address, if you go in your network properties, and click on the TCP/IP properties for your nic, click on advanced.

In advanced, you will be able to add multiple IP for your NIC.

yes sure that pic have only one IP .. but i ment from that place we can add IP's !..
okey thats good but is that possible that i have 1 NIC and added these IP's ...  
1.1.1.1
2.2.2.2
3.3.3.3
with the subnet mask 255.255.255.255 ...
then i can see computers copy files, use internet from coompyers have the following IP's :
1.1.1.55

>>with the subnet mask 255.255.255.255
that won't work.

the subnet mask would still be 255.255.255.0

Subnet Masks are simple to understand, and hard to explain.  It's important to specifically determine how much of an ip address is considered the networkID, and how much is considered the HostID.

Since you want 1.1.1.1 and 1.1.1.55 to be on the same network, they have to have thte same NetworkID.  Subnet masks tell the computer how much of an IP address to considere the network portion, and how much to consider the host portion.  This is done by considering the network bits making up the network portion 1.  Therefore, a subnet mask of 255.255.255.0 allows for a network where the first 3 octets are always the same, and the last one can vary as much as you like (between 1-254)

Since you want the network to be defined by the first 3 octets, then the subnet mask would be 255.255.255.0

This is a very good link to read about the IP addresses and subnet mask.
