Computers play a large role in the modern world. No doubt you realize how crucial they have become to running any business today; they have also become one of the sources of entertainment in our lives. You probably use computers for your everyday tasks as well, such as sending e-mail, paying bills, shopping, reading the latest news on the Internet, or even playing games.
A computer is a sophisticated device. However, it is important to remember that it is still only a device and cannot think on its own. In order to be useful, a computer needs instructions to follow. Facilities such as programming languages allow programmers to provide computers with a list of instructions called programs. These programs tell a computer what actions to perform. As a result, programming languages and computer programs play an important role in today's technology.
