Bài tập Tiếng Anh chuyên ngành Công nghệ thông tin

Throughout the ages people have sought to understand the world around them and to

explain it in a systematic way. A system is simply a group of elements which work together to

achieve a purpose. Systems can be very large, such as the system of courts and laws we call our

'legal system', or very small, such as the system involved in cleaning your teeth. Systems can

occur in nature or be designed by people. The water cycle (described below) is an example of a

natural system. Banking systems and computer systems are examples of systems designed by

people.
