从技术上讲，计算机是可编程机器。这意味着它可以执行程序化的指令列表，并

Technically, computers are programmable machines. This means that it can execute a programmed list of instructions and respond to new instructions given. However, today, the term is most commonly used to refer to desktops and laptops that most people use. When referring to desktop computers, the term "computer" technically refers only to the computer itself, not the monitor, keyboard, and mouse. You can still refer to everything collectively as a computer. If you want to truly become a technical expert, call the box containing the computer a "system unit". <br><br>Some of the main parts of a personal computer (or PC) include the motherboard, CPU, memory (or RAM), hard drive, and video card. Although personal computers are by far the most common type of computer, there are several other types of computers. For example, a "minicomputer" is a powerful computer that can support many users at once. A "mainframe" is a large, high-performance computer that can perform billions of calculations from multiple sources at once. Finally, a "supercomputer" is a machine that can process billions of instructions per second and is used for extremely complex calculations.
