Advantages of technology 

        

• Sharing devices such as printers saves money.Site (software) licences are likely to be cheaper than buying several standalone licences.Files can easily be shared between users.Network users can communicate by email and instant messenger.Security is good - users cannot see other users' files unlike on stand-alone machines.Data is easy to backup as all the data is stored on the file server.
• Technology has positively impacted business activities involving manufacturing, selling, marketing, distribution, recording, etc. Technology has touched almost every sphere of business activities. Businesses need to make wide variety of mathematical calculations for various purposes such as counting, estimation cost and profit, etc. Prior to the introduction of calculators, all these mathematical calculations were done manually. With the introduction of computers, large business data are effectively processed and stored in computers. The growth of eCommerce business is an excellent example of how Information Technology can benefit our life.

• Virtual classes are a delivered at many schools. E-learning is a relatively new concept. Students make use of internet technology to download important study materials in the form of text, audio and videos.
• Emerging technologies such as Information Technology, bio-technology, artificial intelligence, etc. are among the most important technologies of modern times. The introduction of computers, internet, smartphones, etc. have deep impact on common people. Much research are being conducted in the field of artificial intelligence.

Disadvantages of technology 

• Too much use of technology has resulted in an increase in waste products into the environment. This has caused pollution. The discharge of industrial wastes into the environment diminishes the quality of soil, water, air , etc. The vehicle emission is among major causes of air pollution. Excessive use of pesticides in farming has caused soil erosion.
• Thought various technologies have made our life comfortable, they have come at the cost our health. The impure air and water is hazardous to human health. Loud noise of vehicles and running factories disrupts the human auditory senses. Excessive use of smartphones causes stress and posture related health issues.

• Some people waste immense time and energy in doing non-productive activities. For example, internet technology has enabled people to browse the internet for information. However, some people get addicted to internet activities such as browsing, gaming, etc., and waste time and energy.
• We are dependent on technology for all of our task. People are excessively dependent of modern gifts of technologies such as cars, computers, smartphones, etc. They feel helpless if any of these technological equipment, machinery or tool fail to perform. We have adopted technology in our life to an extent that it is impossible to think of performing our day-to-day tasks without the help of technology.
