The way emergency services operate has changed as a result of computers. Computers are used by emergency services including the police, fire, and ambulance departments to respond rapidly to emergencies. They can track and pinpoint the precise position of the incident with the aid of computers, and they can also send the closest personnel to the scene. Because of the greatly shortened reaction times, it is now easier for rescue workers to save lives. By enhancing security across a number of industries, computers have made the world a safer place. In airports, for instance, computers are used to screen travelers and look for any potential dangers. In order to stop theft, vandalism, and unwanted access, residential and commercial properties also utilize computer-based security systems. Over time, these security measures have improved and become more sophisticated, making it more difficult for criminals to compromise them. Computers have significantly contributed to the advancement of medicine, which has led to a safer community. Computers are used by medical experts to monitor patient health and make sickness assessments. Complex medical procedures like surgery and organ transplants are being carried out using computer-based medical technology. Many lives have been saved and patient outcomes have improved thanks to these developments. While these developments help make the world a better place, there are some effects of rapid computerization that are not so great. Cybercrime is one of the main ways that computers have contributed to the world being less secure. Computers can be used by cybercriminals to steal sensitive data, including personal and banking information. They can also launch cyberattacks to harm computer systems and interfere with vital infrastructure, such as water supply and electricity grids. Online harassment and cyberbullying are now commonplace on social media. Computers have made it simpler for people to bully and harass others in an anonymous manner, which can result in emotional suffering and in some cases even lead to suicide. Social media has also been used to spread propaganda and disinformation, which can undermine democracy and stir up civil unrest. Computers have contributed to the increasing issue of screen time and addiction. More people than ever before spend time on their computers and mobile devices, especially young children. Social networking, online games, and other online activities have become addictive as a result of this. Long-term screen use has been associated with a number of detrimental health outcomes, such as depression, sleep deprivation, and obesity. All in all, there are definitely benefits to digitizing the world we live in, but there are also dire consequences.
