A /28 is CIDR notation for the 255.255.255.240 subnet mask. This has a block size of 16 in the fourth octet. Workstation A is in the 192.0.2.16 subnet, Workstation B is in the 192.0.2.96 subnet. Both workstations are in the wrong subnet. Changing the subnet mask to /25 (255.255.255.128), provides two subnets: 0 and 128, which would put both hosts in the zero (0) subnet. With both workstations in the same subnet, you will need a crossover cable in order to be able to communicate between the two hosts.
