Short answer

9. List and describe the three most basic levels of programming languages as discussed in the text and notes. Answer
   • machine language: Machine language is very low level. It is what the CPU can understand and execute, and is therefore machine dependent. It is binary (made up of zeroes and ones). Whatever the programmer writes eventually has to be converted into machine language to run.
   • assembly language: Assembly language is a step up from machine language. It uses menmonics in place of the ones and zeroes of machine language to make programming easier.
   • high-level language: High-level languages are more like a natural language or the mathematical formulas we write. They are problem-oriented and much easier to use than machine and assembly languages. They are often available on many different types of computers and operating systems. One instruction in a high-level language often becomes many instructions in the converted machine language. This is what programmers usually write in currently.
10. Describe what virtual memory is. Answer A computer can pretend to have more RAM than it actually does by using the hard drive to store some data and swapping it with other data in RAM when needed - this is virtual memory.
