Essay 19 - The Use of Computer

Using a computer every day can have more negative than positive effects on your children. Do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience. 

Technology, for the past few decades, has been the driving force behind mankind’s progress by leaps and bounds in almost every field. Technology, along with the information which it brings, has become an integral part of not only adults but children are also becoming avid users of computers, handheld devices and other gadgets. Although the new generation is becoming more aware of day to day happenings, access of everything brings divergent results as well.

Firstly, abuse of computers by youngsters has led them to waste their time on needless tasks rather than using computers in an efficient way. Facebook and other social media sites have played a devastating role in harming the overall working of an effective society. Children now like to spend hours of their precious time posting and reading useless material. They have access to every kind of information, which is causing children to view restricted content as well.

Secondly and more importantly, computers have barred children from engaging in physical activity as well. Children now prefer to limit themselves in their rooms and want to be lost in the fantasies of the online world. This leads children to be ostracized from today’s social happenings and is turning them into social outliers. I know many of my friends who play games, engage in digital social gatherings and wasting their useful time in mind numbing activities

Changes, in fact mind boggling ones, are taking place at societal level, where the balance of a child’s growth is being seriously challenged. This can be averted through proper control and dedication of parents towards their children. Useful things can become detrimental if employed at a wrong stage.
