【作文示范】The Wonderful Structure of a Personal Computer
In Chinese, a computer is popularly known as an “electrical brain”, for the working process of a computer is similar to a human brain very much.
In appearance, a personal computer has three simple and clear parts: the main frame①, the keyboard② and the display③. In other words, if you own these three parts, you would exactly have a computer.
A computer system is made up of software and hardware considering its working manner. If we compare the hardware to a human body, then, the software would be the soul.
Just as a driver cannot drive a car without driving skills or the car it self, you cannot control a computer without controlling techniques or the computer itself. The controlling techniques are called software, while computers themselves and related devices④ such as a mouse⑤ are called hardware.
The work of a computer is just making full use of various resources by a software set in the computer, and directing the hardware to realize marvelous omnipotent⑥ functions.
