  2. To pass the value as argument l,b and calculate area of base of that box in function.
  3. Make a area button to display area of base result and a volume button to display volume of a box.
  4. Make a all button if we click on that it should give output in proper format. (Area is = , Volume is =                                   Output should come in Alert box, Bellow the button, Console area.

  2. In second function, value should be passed and should call the first function. sum(25,30)
  3. When user clicks a button second function should be called and output should come in down side.
Program 4
  1. To calculate square root of sum of any two numbers.
  2. There should be a function to pass two value as an argument. hypotenuse(a,b)
  3. Inside first function there should be second function to make square of individual numbers. square(x)
  4. Internal function should return square value to outer function.
  5. Outer function should find square root of two function's returned value.
  6. Outer function should return the value.
Program 5
  1. Make two text boxes to enter Nepali amount and display result.
  2. Make any three buttons of different country. USA, Canada, Australia

  Basic elements of Communication System Information Source: The term "information source" refers to the origin or starting point of information that needs to be conveyed to a recipient or receiver. It represents the entity or process that generates the data or messages to be communicated. The information source is a fundamental concept in communication theory and plays a crucial role in the overall communication process. Input Transducer: An input transducer, often simply referred to as a transducer, is a device or component that converts one form of energy or physical quantity into another. In the context of electronics and instrumentation, input transducers are used to convert physical phenomena, such as temperature, pressure, light, or sound, into electrical signals that can be measured, processed, or transmitted by electronic systems. Transmitter: A transmitter is a key component responsible for transmitting information or data from the source to the communic
