act Disc Recorder (CDR) in each department. 5.1.4 - Input DeviceKeyboards and scanners will be our only means of input.5.1.5 - Output DeviceMonitors and printers will be our only means of output.5.2 – RESOURCES5.2.1 – HardwareWe estimate 3 additional central hosting computers, 20 workstations, 10 printers, and 10 CDR will be needed.
