Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer. 

Question

4. Consider the following expression: M = U/(V*W+ X*Y - Z). a) List a sequence of instructions
to evaluate this expression on a computer architecture with two-address arithmetic instructions
