      PROGRAMMING LANGUAGES (CHAPTER 15) 
      Practice Test 1: 
      A.  Answer the following Questions: 
      1.  Difference between the following: 
          
         a.  Machine Language and Assembly Language 
         b.  Assembler and Compiler 
         c.  Keywords and Statements 
          
         Answer: 
         a.  The only language that computers understand is something called Machine language. 
            To simplify programming, computer scientists created another programming language 
            called assembly language. 
         b.  Assembler can convert assembly language into machine code. 
            Compiler can convert different programming languages into machine code. 
         c.  Keywords act like bricks that you can combine together to create a program. 
            By combining keywords you can create instructions, called statements, which tell the 
            computer to do something useful. 
      2.  What are functions? 
         Answer: 
            You can combine keywords into miniature programs that you can reuse as bigger, more 
            powerful building blocks, called functions. 
      3.  What is syntax? 
         Answer: 
         The way you combine commands together is known as syntax. 
      B. Write (T) for True or (F) for False:

          INTRODUCTION TO VISUAL BASIC (CHAPTER 16) 
          Practice Test 1: 
          Answer the following Questions: 
              1.  What is BASIC programming language? 
         
               Answer: 
               BASIC  is  a  family  of  general-purpose,  high-level  programming  languages  whose  design 
               philosophy emphasizes ease of use.  
                
              2.  Explain how Visual Basic makes programming easier? 
               Answer: 
               Visual Basic (VB) is an event-driven programming language and environment from Microsoft that 
               provides a graphical user interface (GUI) which allows programmers to modify code by simply 
               dragging and dropping objects and defining their behavior and appearance. 
              3.  Explain the following parts of every program: 
                   i.         User Interface 
                   ii.        Instructions 
                      
               Answer: 
               i.         The user interface (UI) is the point of human-computer interaction and communication in 
                          a device.  
               ii.        An instruction is an order given to a computer processor by a computer program.
