Perfect reliability in digital computers has not yet been achieved by simply designing ruggedness into the equipment components. Nevertheless, it is essential for a computer to perform dependably under all conditions. In certain computer applications, errors resulting in unscheduled maintenance delays can be tolerated, but only at the cost of expensive computer time. In some special military and civil applications, such as the SAGE system and air-traffic control systems, poor equipment reliability can be disastrous since input information not processed when the system is inoperative can become obsolete during the time required for manual recovery. |
