It refers to the number of bits in the subnet mask.  In this case it's
11111111 11111111 11111111 00000000
which translates to
255.255.255.0

24 refers to the number of bits that are 1 (on) in the subnet mask and is a shorter way of writing 255.255.255.0 with this subnet mask there is a possibility of 254 usable IP addresses

It is the subnet mask, a /24 or 255.255.255.0 has 254 hosts.

No, it doesn't refer to the number of computers in the subnet, its as paulmacd said the number of bits in the subnet mask

For your info there are 254 possible IP's for use in a 192.168.1.0/24 subnet -
192.168.1.1 - 192.168.1.254
