You are the chief information technology officer at a small outpatient health care facility in Riyadh. The medical facility employs five specialist physicians, ten certified nurses, five administrative assistants, and two technicians. There are 25 clinical rooms, each equipped with a computer. In addition, five computers are used by the administrative assistants for patient appointments and records. All of these computers are connected using a local area network. Physicians are supplied with portable devices that they can use to write e-prescriptions. These devices are connected wirelessly to the rest of the network.
