COMPUTER FUNDAMENTALS

Detailed explanation-1: -Answer: In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. Hope this helps.

Detailed explanation-2: -Accuracy refers to the degree of exactness with which computations are made and operations are performed. One might spend years in detecting errors in computer calculations or updating a wrong record. Errors attributable to hardware are normally detected and corrected by the computer system itself.

Detailed explanation-3: -Accuracy is how close the measured data is to the actual value. For example, if you know that you have a mass standard that is 50.00 grams, and you measure it to be 49.98 grams, then your measurement is very accurate.

Detailed explanation-4: -Speed − Typically, a computer can carry out 3-4 million instructions per second. Accuracy − Computers exhibit a very high degree of accuracy. Errors that may occur are usually due to inaccurate data, wrong instructions or bug in chips – all human errors.
