    Why don't you try these two links for starters.

    Subnet:

    VLAN:

    http://www.google.com/search?hl=en&lr=&safe=off&oi=defmore&q=define:VLAN

    In short, a subnet is a network defined by the number of bits allocated for network versus hosts addresses. A subnet can only communicate with another subnet through a router. All computers on the same subnet can communicate with each other without a router and are usually joined by a hub or switch.

    A VLAN or Virtual LAN can contain computers from different subnets, allowing them to communicate as if they were on the same subnet. Usually, VLANs are configured using management software on a switch to associate the designated computers as being on the same logical network, even though they are on different physical networks.

    I know that's probably clear as mud. Take a look at the links below to see if they make it clearer for you:

    Hope that helps some.
