Topic 1.1. The computer in human life

A Grade 7 topic in Computer Science: “Topic 1.1. The computer in human life” (pp. 10–11, I. N. Tsybulya, L. A. Samykbaeva et al.). Information technology (IT) is becoming part of our everyday life: it makes life convenient and safe and helps us solve problems quickly. Artificial intelligence, virtual and augmented reality and 3D printing are now widely used. At the same time, sitting at a computer for a long time changes the nervous, endocrine and immune systems and harms the musculoskeletal system and the eyes. Hypodynamia is a lack of movement of the body. To stay healthy, continuous work at a computer should not exceed 20 minutes, the eyes should be 50–70 cm from the screen, and light exercises should be done during breaks.
