subnetting confusion

My network has 70 PCs on it. I am using a Class C private IP addresses
range (192.168.1.1-192.168.1.254) distributed via DHCP. My current subnet
mask is the default 255.255.255.0. My current IP address leases are
192.168.1.11 through 192.168.1.204 (with a few exclusions).
I am a bit confused about the whole concept of subnetting, private IP
address, network classes, etc, etc. Say I want to put seven of my computers
from the registration department on a different subnet, by adjusting their
subnet mask. How would I accomplish this? Is it correct to say that these
computers would no longer be able to communicate with computers with a
subnet mask of 255.255.255.0?
Are DHCP superscopes used to accomplish what I am talking about an easier
way?
Thanks in advance
