Slow response time in computer systems has been found to reduce job satisfaction and increase stress and mental strain. On the other hand, very fast interaction to an uncomfortable level where users feel they must always respond to the system promptly. The optimum response time will depend on the task. Variability in systems response time and system crashes may also cause stress in users. It was reported in one of the studies that the workers in an insurance company worked very quickly in the morning to try and complete as much work as possible, in case the system failed in the afternoon. In addition, when response times were usually long, workers experienced anxiety and uncertainty as they could not be sure if the long response times were due to high load on the system, or whether the system had failed.
Inference: Most system failures had occurred in the afternoon in the insurance company.

As in case of absolute number of illiterates, the actual numberof illiterate
females is also increasing with time and faster than the number of male
illiterates. More so in the backward states, in the rural areas, and among

males.
