what does the subnet mask (24) translate into based on a xxx.xxx.xxx.xxx format for a network address 192.168.1.x?

Subnet masks are 32 bits long, just like IP addresses. Start from the left of xxx.xxx.xxx.xxx and give 24 "highs" or "ones" (binary). This gives 255.255.255.0. For your network of 192.168.1.x this will mean that all machine IPs beginning with 192.168.x can talk without having to be routed.
