Programming as a Career
Computer Programmers are at the center of the information technology (IT) field. These days, we rely on all kinds of programmable devices-our laptops, personal computers, personal digital assistants (PDAs), in-car global positioning systems, factory robotics systems, and more. None of these things would function without programmers, though, who give programmable devices specific, accurate instructions on how to perform their various functions. Your PC, for example, is nothing more than a dumb box without the input of programmers. It can't solve even a simple math problem without a series of programming commands to tell it how to do so.
A computer programmer creates the code for software applications and operating systems. After a software developer or computer software engineer designs a computer program, the programmer writes code that converts that design into a set of instructions a computer can follow. He or she tests the program to look for errors and then rewrites it until it is debugged or error-free. A programmer continues to evaluate programs that are in use, making updates and adjustments as needed.
