Worked example

(a) Model answer

Server: Windows Server (or a Linux server such as Ubuntu Server or Red Hat Enterprise Linux). Designed for servers: runs 24 hours a day and supports many users at once. Central user accounts and permissions (Active Directory), so each department sees only the records it needs — important for confidential data. Supported by the hospital system's supplier, with regular security updates and long-term support. Built-in tools for backup, remote management and monitoring. (Linux reasons: very stable, no licence fee for many versions, strong security — if the hospital system supports it.) Other computers: Windows 11 Pro. Staff already know it, so less training is needed. Works with the hospital system and with peripherals such as barcode scanners and receipt printers (drivers available). Can join the server's domain, so staff log in with their own accounts and settings are controlled centrally. Includes security features such as BitLocker encryption and Windows Defender.
