Question

Suresh Chand · Accepted Answer

The characteristics of the computer system are as follows − 1.Speed A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations 2. Accuracy Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy 3. Diligence A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration 4. Versatility Versatility refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency. 5. Reliability A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result. 6. Automation Computer performs all the tasks automatically i.e. it performs tasks without manual intervention. 7. Memory A computer has built-in memory called primary memory where it stores data. Secondary storage are removable devices such as CDs, pen drives, etc., which are also used to store data. Difference between Analog and Digital Computer: S.No. ANALOG COMPUTER DIGITAL COMPUTER 01. Analog computers works with continuous values or these types of systems process continuous data. Digital computers works with discrete values or these types of systems process discrete data. 02. Speed of analog computers is less than the digital computers. Speed of digital computers is more than the analog computers. 03. Analog computer has very low or limited memory and it can store less amount of data. Digital computer has very big memory it can store large amount of data. 04. Analog computer has no state. Digital computer has On and Off these 2 steps. 05. Analog computers are less reliable than digital computers. Digital computers are more reliable than analog computers. 06. Its performance is comparatively low. Its performance is very high. 07. Its speed of processing is not so high. Its speed of processing is very high. 08. Analog computers depends upon physical variations. Digital computers does not depend upon physical variations. 09. It provides results with less accuracy as compared to digital computers. It provides results with higher accuracy as compared to analog computers. 10. Analog computers are difficult to use. Digital computers are not so difficult to use. 11. Analog computers have complex architecture. Digital computers do not have so complex architecture like analog computers. 12. Readability of analog computer is low. Readability of digital computer is high. 13. Analog computers show the result in terms of voltage signals. Digital computers show the result in computer display screen. 14. Analog computers employs analog encoding. Digital computers employs digital encoding. 15. Power consumption is high. Power consumption is low. 16. They are usually special purpose devices. It can be general purpose devices. 17. Examples includes analog clock and thermometer etc. Examples includes Digital laptop, digital camera, digital watches etc. Source: geeksforgeeks and tutorialspoint
