Accuracy – computers are capable to work consistently with almost 100% accuracy, errors may occur in computer system only because of wrong human input. storage capacity – computer can store vast amount of data. It can also quickly retrieve data from storage devices Diligence – computer never gets tired or lacks its concentration. It can work for hours without any fault. Versatility – it has the ability to perform completely different kinds of works with the same accuracy and efficiency at the same time power of remembering – it has the power to store any data as long as we like. It can retrieve / recalled easily if needed even if its been years of storage. no IQ and no feeling – it cannot think or feel like humans. They only work according to instructions given.
- 6. LIMITATIONS OF COMPUTERS lacks common sense – it cannot make decision based on a simple situation. No Learning Power – they cannot learn even if they already perform same task for a long period of time. Power Dependent – electric power is needed to operate and errors can occur in an event of a breakdown of the system Dependent to humans - Computer itself cannot function. It needs instructions to perform task.
