Without a subnet mask a client is not able to participate on a network because the network software is unable to determine the network addresses.
The no. of IP's that can be assigned to single computer depends on the subnet mask. if the subnet mask is of A class then the IP's assigned can be 16777216. If the subnet mask is of B class then the no. of IP's that can be assigned is 65536. And if the subnet mask is of C class then the IP's assigned can be 254.

It does not require a subnet mask.
If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.

If the other PC is on the same LAN segment then it will have the same subnet mask as yours. A subnet mask is the same for all subnets within a network so that will be the same as well. For other networks it isn't important to know what their subnet is. You could always ask the other user to find out that information if you needed to know.
The default subnet mask has a standard size. The custom subnet mask allows you to make subnets that are smaller or larger than the default.
What if your company is assigned a network address of 150.50.0.0 you need to create 4 subnets all having access to the internet what is the correct subnet mask for the network
A subnet mask is something that divides the IP address into a host and network. It is a very confusing thing but it will also let you see the IP address of the user.

The correct term is subnet mask instead of subnet mass. A subnet mask separates an IP address into the host address and the network address. It is a 32-bit number that can mask an IP address.
