Advantages of Science and Technology
The vast improvements made in the field of medicine have served to lengthen our life expectancy and to reduce the rate of infant mortality. The discovery of mechanization, better seeds, better techniques of irrigation and pest control, has worked to increase productivity levels on farms. In transportation, railway, modern ocean liner, jet plane, and motor vehicle have made our lives more comfortable and provided great possibilities for modern commercial development and industrialization. The invention of the computer has assisted the process of calculation in laboratories Technology has made communication much simpler in recent times. Science has brought about groundbreaking solutions to numerous deadly diseases. Man is able to explore the space extensively because of the wide-scale development in technology. Our life has become healthier and longer. Modern hygiene, sanitation, medicine and surgery are conquering more and more physical and mental ills day by day. We now know and experience the joys of good health and longevity. Disadvantages of Science and TechnologyMachines have led to unemployment. They have polluted water and atmosphere. They have caused noise pollution. Factories have led to slums where human beings live in squalor. Our moral and spiritual progress has failed to keep pace with our scientific progress. We have allowed science to master us instead of using it as our servant. Machines make us mechanical, deaden our sensibilities, stifle our creative talents, force mechanical regularity, uniformity and boredom upon us, increase our wants and desires, and tend to make us selfish, greedy and cruel. Geographical distance has, no doubt, vanished, but the gulf between the minds and hearts of man has widened. Machines have given man leisure, but man misuses it to get cheap and vulgar entertainment which destroys his physical and mental health.Again, science has put in our hand’s such fiendish weapons as a nuclear bomb, the guided missile and means of chemical and biological warfare.

1. They are convenient.
It’s great being able to call a friend when you are out and about – without being tied to a land line.
2. They can be life savers.
Taking a mobile phone with you when you go hiking is a basic safety precaution. If you lose your way or get stuck in bad weather, your mobile phone could just save your life.
Top 10 Disadvantages of Mobile Phones:1. Dependency
It is easier than you might think to become addicted to your mobile phone, and so dependent on it that you forget to communicate in real life.
. Isolation
It’s ironic, but some people feel that the cellphone (which is designed to keep people connected) can actually drive us further apart. Have you ever seen a group of friends at a restaurant, looking down at their phones instead of each other? That.
6. Security issues
If someone taps in to your data they could steal your identity, pilfer your photos, and erase your contacts list.

*Advantages of computers in schools
This handheld device allows students to solve complex problems quickly and efficiently. In addition, it can reduce problems for simple tasks and allow students to spend more time in understanding the problem. Second, they are saved from monotonous calculations and the same boring process
*Disadvantages of computers
The picture is actually very different from what we discussed above. The advantages are not attractive and sometimes difficult situations can lower a student's confidence.
In the beginning, the brand might be the best on the market, but it's still a device. Power and efficiency are completely dependent on the capabilities of the operator. Students must know the instructions given in the manual. For example, the computer casio fx 570vn plus is very popular with students.
Calculators are available in many brands and each brand and model requires a specific set of instructions. It's a proven fact that many of us don't bother to read the manual, and it gets lost. Although the instructions are very simple, there are chances that students can make mistakes. One small mistake is enough to incorrect the answer. The student must be able to estimate the correct answer or the student will not recheck the problem
