Programming a computer is creating a sequence of instructions that enable the computer to do something.1 The people who program computers (called programmers) use a programming language to communicate with a computer. You might have heard of some of these languages in the past such as Visual Basic, C++, or Fortran. Even though you may use Windows XP or Vista, batch files can save you tons of time by automatically starting multiple programs and performing different tasks at the single click of a button. They don't require any extensive programming background and they don't need to be encrypted with some weird, expensive compiler. Customizing your PC is what makes using a computer truly unique and enjoyable, so have fun and build a situation at home or a work in which you'll love to work with everyday.
