                                Computer architecture   Block diagram of a basic computer with uniprocessor CPU. Black lines indicate data flow, whereas red lines indicate control flow. Arrows indicate the direction of flow. In  computer engineering ,  computer architecture  is a description of the structure of a  computer  system made from component parts. It can sometimes be a high-level description that ignores details of the implementation. At a more detailed level, the description may include the  instruction set architecture  design,  microarchitecture  design,  logic design , and  implementation . [3] History The first documented computer architecture was in the correspondence between  Charles Babbage  and  Ada Lovelace , describing the  analytical engine . When building the computer  Z1  in 1936,  Kon...

  Calculator program using Python     Create a simple calculator which can perform basic arithmetic operations like addition, subtraction, multiplication, or division depending upon the user input. Approach : User chooses the desired operation. Options 1, 2, 3, and 4 are valid. Two numbers are taken and an if…elif…else branching is used to execute a particular section. Using functions add(), subtract(), multiply() and divide() evaluate respective operations. Please select operation - 1. Add 2. Subtract 3. Multiply 4. Divide Select operations form 1, 2, 3, 4 : 1 Enter first number : 20 Enter second number : 13 20 + 13 = 33 Python # Python program for simple calculator   # Function to add two numbers def add(num1, num2):      return num1 + num2   # Function to subtract two numbers def subtract(num1, num2):      return num1 - num2   # Function to multiply two numbers def multiply(num1, num2):   ...
