Computer A computer is an electronic device that is designed to work with information. The computer takes information in, processes that information, and then displays the results. In this way, a computer is similar to a calculator, except that even the smallest computer is much more versatile than the most powerful calculator. Computers operate at amazingly fast speeds, with a typical computer processing millions of calculations every second.

Personal Computer A personal computer is a small, relatively inexpensive computer that is designed for use by one person at a time. It allows you to perform personal tasks such as creating documents, communicating with other people, and playing games. The abbreviation PC is most often used to refer to computers that run the Microsoft Windows operating system, as well as to differentiate them from Macintosh computers.

Speed Computers allow you to perform many everyday tasks more quickly. For example, if you mail a letter to a friend, he may receive it in a few days. However, if you e-mail him, he receives your message in a few minutes. Similarly, if you manually compose a newsletter, it may take you a week, whereas using a computer, it may take just an afternoon. Quality The tools that come with a computer enable you to create high-quality documents and drawings, even if you are not a typesetter or an artist. With just a few simple techniques, you can create documents that look professional or are exactly suited to your present task.

New Skills Because we live in a computer age, you often require basic computer skills to accomplish many daily tasks. Typing on a keyboard, using a mouse, and other basic computer skills are useful in many different situations and are often required by employers.
